All you need to Know about High Voltage Cable

If you want to transfer large amount of electricity, then high voltage cables are your safest bet. There are various forms of these cables, and all are used for different purposes depending upon voltage of electricity and the machines for which these are used. Three types of cables are: high, medium, and low voltage cables. Out of these, high voltage cables are used when the voltage is above 1000 V. These cables are heavily insulated to prevent any risks or hazards.

  • AC power cables

These cables are used to transfer up to 2000 V of electricity. The composition of these cables includes cross section of cable, polyethylene insulation, and conductive material like aluminum or copper. These cables are highly flexible and work well both in low as well as high temperatures. The cable layers are fused together to avoid air seeping in, as this can cause electrical discharge, thereby damaging the insulation.

  • HVDC cables

These are specialized cables that are designed for high voltage direct currents, and thus are called HVDC cables. If you have seen a power line, then it would be easy to understand, as a power line is also an HVDC cable. These cables are helpful in carrying large loads of electricity over longer distances. After reaching the transformer, their electricity is converted to AC form. Thereon it runs with lower voltage, and is transferred to businesses and homes.

  • X-ray cables

These cables are used to link other high voltage cables with X ray machines. These are also used to connect high voltage cables to other scientific equipment that require higher loads of electricity. These are highly flexible cables. They have a braided cover of copper wires, and are insulated with rubber. These are fused to high voltage cable to provide safety, and to reduce the hazards of electric shocks.

All these cables are not for home use. These are used to connect high power sources to other devices or cables. If you want to buy these cables, make sure you go for the best quality, as bad cables can lead to dangerous situations.

Using PTFE wire for High Temperatures

Wire insulated with PTFE, or PTFE wire, is very useful. If you have been using PVC hook up wire to fight insulation melt downs, then you will be pleased to use PTFE. It cannot even get affected by a soldering iron. It has been used since the 1960’s due to its excellent performance in high temperature scenarios. Some companies also use it in classification of surface electronics.

PTFE wire has got copper strands, plated with sliver. The silver plating, along with PTFE insulation helps the wire to sustain extremely high temperatures. It is much better than basic hook up wire that suffers from melt downs in high temperatures. And due to its great heat withstanding ability, PTFE wire comes expensive. But in case your needs are about wiring places with extremely high temperatures, it will be a good investment in the long run.

This wire is made by following many methods. Two of the more common methods are wrapping and extrusion. Extrusion is the most common one and is done usually in the standard sizes of 24 AWG and 22 AWG. There are also some smaller sizes, where space is an important factor. The covering comes in fused and wrapped types. PTFE is also used as the outer jacket of co-axial cables.

PTFE wires also have great resistance to moisture, flame, damage from soldering iron, and thermal aging. Apart from that, the PTFE (polytetrafluoroethylene) coating is able to resist many harsh chemicals, ozone, greases, and solvents.

You can install these wires at many places, as they are very easy to fix. It also has low degree of power loss, and thus is great for high frequency usage. Because these wires are small and slippery, they can be used almost anywhere.

PTFE or Extruded PTFE hook up wire has 3 types: Type E (most commonly used, and rated for 600 V), Type EE (having thicker PTFE jacket, and rated for 1000 V), and Type ET (having thin cover, and rated for 250 V). All 3 of them can be used for temperatures up to 200o C

Basics of Bare Copper Wire

We all know that of all the metals used all around the planet, copper is the number one metal in terms of its usage. This is because it is the most versatile metal, and it touches the lives of people in one way or the other. It has a significant role to play in electrical engineering branch in various ways. It has great conductivity power, and thus is used a lot in making electrical wire. Although there are many other available metals as well, but none can beat the versatility of copper.

Copper wire is available in both forms- with and without insulation. It depends upon the engineers- whether they want insulation or not. Depending upon where they are using the wire, they decide if it should have insulation or not. Both insulated and bare copper wires are used in different applications. They have their use in different engineering segments.

The bare copper wire is also called ground wire, since it has no protection or insulation. This wire is generally used as the platform for various wires and cables.

This wire can come either in solid form, or in small AWG sizes, wrapped to make some specific gauge. Experts say that using small AWG sized wire allows more flexibility to the wire, and it bends easily around the corners. Although flexibility is a good thing, but not in all cases, so a solid form bare copper wire is preferred in many scenarios. For example, electrical contractors require stiff wires, so that the wire could be sent through a conduit for longer distances.

Green THHN wire is called ground wire, particularly when that wire has to be used outdoors. It is used for grounding purposes to safeguard people against hazards.

So this is where bare copper wire is used. But before you purchase this wire, you must make sure that the company you are buying it from is a good and trusted one. One simple solution is to look for this wire online. You can find many trusted online companies that can provide you the kind of bare copper wire you want.

Scrap Metal TV Show ‘Scrappers’ in Bronx, NY

In the copper wire business we come across many ‘scrappers’ who want every bit of wire we have in stock for our customers to make a quick buck and they offer cash for it. It looks like a tough job and with the worth of scrap metals these days I’m sure the security is tough as well. That, compiled with it being located in Bronx, NY makes me believe these guys are some tough SOB’s out to make a tough buck.

Hopefully broadcasting scrap metal will bring the crime level down on the booming market because people are getting hurt and losing a lot of money along the way. A ‘scrapper’ business mind might think, “How can I get more scrap and make more money?”. A thief might think “Look at that vacant home, or building, I bet there’s a lot of electrical wire in there to steal and scrap”. Not only that but thieves are attempting to take LIVE WIRES assuming that cutting the wire will just break the connection instead of electrocuting them?!

I assume this will be a very popular show due to the controversy of theft in the industry. I suspect people will be trying to rob the scrap yard and many problems will arise with tough negotiation acquiring the metals. I’m sure a fair share of co-worker drama will fill in the gaps between theft and standardized living in the Bronx.

Types of Insulation- Hook Up Wire

If you are using PVC hook up wire for electrical purposes, you should know about the insulation that you can use with this wire.

UL 1007

This wire is a form of hook up wire, which is particularly used for 300 V PVC cable that runs at about 0.016 inches of thickness of the insulation material. The popularity of the term UL grew a lot because the UL confirms that a wire can withstand the voltage and temperature that it claims to handle. Therefore, UL 1007 cable is endorsed by UL to work at 300 V, as it is mentioned on its specification sheet.

UL 1061

UL 1061 is another PVC hook up wire that is quite similar to UL 1007. It has 0.009 inches of thickness of insulation material. Like UL 1007, it also supports 300 V. It is generally used with the appliances that need an outlet with smaller diameter.

UL 1015

Yet another PVC hook up wire, the UL 1015 supports 600 V, as opposed to 300 V supported by UL 1007 and UL 1061. Since it supports higher voltage, it needs thicker insulation. The thickness of insulation material for this cable is 0.032 inches. The range of this wire is from 10 awg to 24 awg- but before the UL type could change.

PTFE

PTFE is another type of hook up wire. It supports insulation at high temperatures going up to 200 degree Celsius. Other PVC insulations work up to temperatures of 105 degree Celsius. Apart from the temperature difference, PTFE has copper plated with silver, and not tinned copper. This feature also helps it to sustain high temperatures.

These wires were some of the hook up wires that you could use while working on an electric application. Some of these cables cannot stand too much wear and tear, and so they are more suited for indoor works, while some cables are rough and tough, and so can be used outdoors as well as underground. Before you buy any type of wire, you must consult your electrician and take his opinion.

Copper Thief Shuts Down Power to Airport!

It’s hard to understand that thieves will do almost anything to get their hands on some high value copper electrical wire. Well watch this video to fully understand because this man almost gave up his LIFE for some electrical cables that he would’ve tried to scrap for cash.

After researching the topic a bit more I’ve realized many people have already died in attempt to steal scrap metals such as this. You might think these guys are clever for attempting such a robbery that’s nearly untraceable but failing to shut off the power before doing so proves otherwise; Almost dying, or in fact dying, seconds that…

In this particular instance the restricted area was marked High Voltage in many areas as it was powering an entire airport. However this man could only see dollar signs as he entered and, to his surprise, the back of an ambulance as he made his exit. Lucky to be alive and unlucky to be the butt of many jokes to come.

Save Your Romex Wire!

I’m sure most electrical contractors know about the fluctuation of copper pricing in the last few years which means they understand they need to keep all excess copper wire to scrap later on. Copper has been as low as .86 per pound and as high as 4.10 per pound so the stock market slogan “buy low, sell high” comes into play here.

Sometimes electrical contractors tell the homeowner to find the wire and cable they need on their own to save a few dollars on the cost of the installation. However, they may not know that they can sell the unused wire to a scrap yard for cash. You can call them and ask what the current copper price is and they’ll give you a little bit less than what you might see on the NYSE. Then they melt down the copper and sell it to copper wire manufacturers to make a profit.

Currently copper is about 3.30 per pound so if you have 50 ft of Romex 6/3 then you can probably get about $55.00. Romex 6 awg 3 conductor weighs about .357/foot and you can get about 3.00 per pound right now. So it adds up quicker than you think.

Be careful of those copper thieves out there though! We have another blog post with a video showing all the people stealing copper wire to scrap it for cash. They’re stealing it from live connections (some are getting electrocuted) and anywhere else they can find it because it’s worth so much right now and it’s so easy to scrap for cash.

How and Why to Become ISO 9001 Certified

WesBell Electronics is an Electrical Wire and Cable Distributor - ISO 9001 Certified

Some companies have a very bad outlook towards an ISO certification because it entails a lot of extra paperwork to do something that might take 5 seconds. Well, while that’s true, ISO has many advantages that can help take a company to the next step and the paperwork is for you to analyze..

How to become ISO Certified

Most companies hire an ISO consultant to set up all of the initial documents that need to be implemented and then take care of following the procedures themselves. The ISO consultant will discuss each step along the way and explain the points and advantages of having the certification.

Most likely one of your customers has stressed the importance of your company, as a vendor, becoming certified so you have started to research the idea. Instead of thinking about it as a pain, think about it as a way to improve your every day procedures and document them. The idea behind ISO in the first place is “continuous improvement” for the organization, not more sales to customers. However, with continuous improvement comes more sales from customers.

Now that you’re certified – How much paperwork is involved?

It really isn’t as bad as you think. Paperwork only comes when something is done wrong and even then it’s only filling out one page to document the wrong doing for future analyzation.

Assume you get a call from a customer saying you shipped the wrong product and they want the correct material ASAP. First things first, get them the correct material right away no questions asked (Yes Sir, Yes Sir, Yes Sir). Isn’t that how you’d like the phone call to go if you received incorrect material from your vendor?

Now you need to document (NCMR – Nonconforming Materials Report) exactly where you went wrong. Was it the salesperson who entered the wrong item? Was it the shipping dept who picked the wrong item? Was the address mixed up with another pick ticket on the shipping bench? Once that’s filled out, That’s it! File it and call it a day.

Three months later pull out all of the NCMR’s that were filled out to analyze what you need for “Continuous Improvement” of the organization. Assume you come across 4 NCMR documents that show one salesperson writing up the wrong item every time! Well that could mean a few things such as the person isn’t educated enough for the job and can’t handle it, the person isn’t trained enough or complete carelessness on their day to day duties.

Starting to get it? You can technically be ISO without the certification by documenting everything and continuously improve on your own. Keep track of EVERYTHING worth analyzing later such as NCMR’s, customer feedback, on time shipping to customers and on time shipping from vendors. Even keep track of employees, good and bad, to weigh the pros and cons before taking action on anything serious.

ISO allows you to keep track on paper instead of just in your head! Documentation solves discussions and arguements very quickly so don’t think of the “paperwork” as a bad thing for your organization to implement!

People Stealing Copper Wire

Watch this video to see these money hungry people stealing copper wire from anywhere they can find it. They are shutting down power and taking the wires to scrap them at a copper scrap yard for about $3.00 per pound.

Copper has been fluctuating quite a bit over the last few years bringing copper’s worth from about $0.86 per pound to $4.00 per pound. On its way up this ladder people became aware of the amount of money to be gained by scrapping it.

Scrapping electrical wire, telephone wire, welding cable or any other type of power cable is actually very easy because there’s no trace! Once you sell the copper scrap to the scrap yard and receive your CASH there is no trace back to you. It sounds similar to stripping cars to me!

Places like this are actually quite useful to a company such as ours because we have a lot of scrap and waste build up over a months time that we like to bring down to the scrap yard for some extra cash. However, these thieves are giving copper wire and scrap yards a very bad name.

It appears copper scrap yards are going to have to start screening or taking photo ID’s in able to have a trace back to who brought it there incase of a lawsuit.
