There are many different kinds of high temperature wire. The type ET wire however has a silver plated copper conductor. Then there is the PTFE insulation wrapped around the wire. Between the silver plating and the insulation that is what allows this wire to be able to withstand such high temperatures. The fact that these wires can withstand such high temperatures make them ideal for use in electrical work as well as in electronics.
Bare Copper Strands
When it comes to a copper conductor the more strands of copper there are the more flexible the wire can become. If there is a solid bare copper conductor than there is not a lot of flexibility, then the larger the size of the wire, the harder the copper becomes to bend if it will even bend at all. The smaller strands make for a better and more flexible wire.
The silver coating on the copper helps the wire to have a longer life. The silver on the copper helps to prevent corrosion in high temperatures. This is what makes the silver plated wire the ideal choice for high frequency and high temperature wire. The wire is rated to be able to handle temperatures reaching as high as 200°C. It is also rated to be able to handle 250 volts of electricity. The wire also meets all of the M16878/6 approvals.
The PTFE insulation is what allows the wire to be used for high temperature applications. This kind of insulation is non-stick and feeling slippery, it is intended to be used for electrical or electronic usage. The insulation helps to prevent thermal aging, solder iron damage, as well as resist flame and moisture damage. It is also very resistant to solvents, greases, ozone, and a lot of other chemicals. With the insulation being so resistant to so many different things this wire is going to work well in many different environments and applications.
The PTFE insulation is great. It protects the wire from almost anything that can be spilt on it. The insulation also helps to make sure that the wire can withstand the high temperatures of the environment it was intended for. The slick insulation also allows for quick and easy installation of the wires. Type ET wire also has excellent, stable electrical characteristic with low power loss which makes it ideal for high frequency applications. The silver plated copper will last longer than a regular copper wire because the silver adds protection and prolongs the life of the wire.
