Olflex SDP TC Severe Duty Power Cable

The Olflex® SDP TC Severe Duty Power cable, or simply SDP TC, is a Bus Drop approval cable that has some unique features that it has when compared to other Olflex® cables. One of those is the orange elastometric alloy jacket that covers the wiring. This elastometric alloy jacket is also TC-ER approved passing all UL standards that run for 600 volts. This means that you can apply this kind of cable for both commercial and industrial conditions, in cold and other hazardous environments, for control and/or power applications, and even for machine tools or in the electrical circuitry of factory installations. The heavy-duty wire, aside from being approved for 600 volts, is also approved for use in 1000 volts.

This cable goes has still more unique features compared to other motor supply cables. The finer stranding that it has gives it a little more edge. Its wire is also covered with pressure extruded jackets that make this cable a very flexible property for installation. The design of this wire also conforms to NOM and CE standards that make it a globally acceptable solution for wiring.

The construction of this wire is made of finely stranded tinned copper wires. These wires are then covered PVC or nylon insulations, which makes it a little different to other Olflex® cables which are covered with the special formulation of Lapp Surge Guard®. This, however, does not decrease the efficiency of this wire as it compensates with barrier tapes and a specially formulated elastometric alloy jacket.
This jacket makes this wire highly resistant against oil and other chemical intrusions that can cause damages or decrease in conductivity. Aside from the oil and chemical-resistant version, submersible pump approvals are also available in special orders. The Olflex® SDP TC Severe Duty Power cable is highly resistant against heat, though it could only burn or melt when exposed to extremely high temperatures. On the other hand, it is not very flexible so it is not really recommended for electrical machineries that require perpetual motion. However, this wire scores very high when it comes to toughness and mechanical rigidity.

The minimum bending radius for installing this wire is rated at 7.5 times the diameter of the cable. For example, if you have this wire in 26 awg, then you can multiply it by 7.5 to get the minimum bending radius for a 26 awg Olflex® SDP TC. This wire can work for temperatures as low as -40°C to even temperatures beyond 150°C. The nominal voltage that you can use this wire can be in 600-volts (based on UL-TC) or in 1000-volts (based on UL AWM), yet its test voltage can reach to even up to 4000 volts. Like other Olflex® cables, the Olflex® SDP TC Severe Duty Power cable can also be used for variable frequency drives of VFD’s. Yet at the same time, unlike other VFD cables, this one can also be used for non-linear power distortions that can be sometimes associated with other VFD’s.

Why Use PVC Electronic Hook Up Wire?

An electrical conduit is mainly a passageway wherein electricity can travel. It is also considered a type of tubing utilized in creating or assembling machines. It is popularly known to be employed for the distribution and protection of electrical wire. It is also useful in hydraulics schemes such as plumbing and sewage. There are specific kinds of electrical conduits invented and assembled for every special purpose or function. Electrical conduits come in various styles which are mainly used for electrical wiring within places that are out in the open. These conduits can also be made use of in locations that may be found in any part of a person’s house such as the laundry area, the basement and even the garage. These things can even be utilized within the walls.

As mentioned above, most of these electrical conduits are employed for outdoor wiring and the most recommended for such purpose is the PVC conduit oftentimes utilized to be applied in undergrounds or damp settings. This specific type of conduit has connectors, elbows, couplings and PVC fittings. So, why use PVC electronic wire? One reason is because PVC comes in various forms such as semi-rigid, rigid and flexible. A semi-rigid PVC conduit can be bended therefore can be useful in thin walls. Rigid PVC, on the other hand, usually comes in 10-foot span and in standard thickness but it cannot be curved or twisted. While flexible PVC can be utilized for paths that are coiled or entwined.

So, why use PVC electronic wire? PVC electronic wires are very simple to put together by means of PVC glue and a cleaner. PVC electrical wires can also serve for safety and regulation intentions of the wiring route. There are some properties of PVC that make it more reasonable for using PVC wire for outdoor locations. First on the list is that these wires are light in weight and not too pricey. Second reason is that these are available in various thicknesses which make them more useful for a specific purpose depending on the conditions for installation. Third reason is that these wires do not easily fracture for being exposed to sunlight mainly because these are UV stable. The fourth reason is that PVC is resistant to corrosion which means that these wires can be used for works above or under the ground. Fifth reason for using PVC is that these conduits are resistant to abrasion making it avoid cracks and scratches. And the last reason is that PVC is water and moisture resistant which lead to a prolonged life for the PVC to function.

Why use PVC electronic wire for outdoor installations? There is one perfect answer for this question. And this is because PVC electronic wires are weather resistant. This, of course, is based on the properties presented above. This is also one popular reason for most people who choose to make use of these conduits because of the fact that these wires can stand any temperature. This is why PVC electronic wire became a popular choice for cable protection.

Pros and Cons of Using the PTFE 18 AWG Wire

For those who love fixing things or simply want to have things done on their own, knowledge about different types of hookup wires is very valuable. Not being able to use the most appropriate type of wire for each job will not only lead to waste of time and money. It can also be very dangerous and can pose a threat to one’s life and the safety of his family or workplace. For instance, it is important to know that for projects requiring high temperature wire, the best option is the PTFE 18 AWG wire. Let us take a closer look at its characteristics, as well as the pros and cons of using this type of wire.

There are different types of PTFE wire. The most typical types are Type E, Type EE, Type ET and the STJ or shielded tape jacket version. The difference between these types is dictated by the following: voltage, ampacity and appearance. In terms of voltage, STJ and Type E can accommodate 600 volts. Type EE is best for 1,000 volts, while Type ET is suited for 250 volts. The next point for comparison is ampacity, or the amount of current that the wires can conduct. Usually, this is directly proportional to the voltage, so higher currents would requires a wire that can also accommodate high voltage. The last identifier among these types is appearance. For instance, the STJ cables have two sub-types – shielded and unshielded. Choosing between these two types would be based on additional factors such as the probability of the equipment incurring a temperature higher than 200 degrees Celsius, thus needing more insulation for safety reasons.

The PTFE 18 AWG wire is a good buy because it is available in the different types mentioned above. In addition, it has a stranding of 19/30 or 19 strands of 30 AWG wires. The diameter is also good at 0.07 inches. It also has several approvals such as the UL 1213, VW-1 Flame Test, and Mil Spec M16878/4. It is also RoHS Compliant so there is no need to worry about any hazardous risks coming from using the wire.

The only downside of using this wire is the price. PTFE wires already cost more than other types of electrical or hook up wire, because of the need for a better insulation for the high temperature. This type of wire, however, is one of the priciest types of PTFE wire that is currently in the market. Thus, some people would opt for other PTFE cables that are less expensive, unless of course the particular job or equipment they are working on specifically requires the stranding and wire gauge that this wire offers.

Overall, the PTFE 18 AWG Wire is a nice catch and a wonderful option among the different types of high temperature wires. Its quality and durability can be helpful in completing work around the house or even in commercial locations. The only setback in using this type is its price. However, if you cannot compromise quality and safety over expenses, then this is the best option.
