A high-temperature cable is a cable whose conductor material is a multi-strand soft copper conductor. Heat-resistant and high-temperature wires and cables are generally determined by two requirements. The first is the high ambient temperature of the wire and cable, and the cable can normally transmit signals or electric energy under high temperature for a long time; the other is the power transmission cable, which is mainly aimed at increasing the interception capacity. Today Shen Yuan is going to talk about the physical characteristics of high-temperature cables. Let's take a look at it together.
1.Corrosion resistance, PTFE is widely used in industries requiring high temperature resistance and high viscosity. Among them, the strong super acid-fluoroantimonic acid can also be used for preservation.
2. Heat resistance, PTFE coating film has excellent heat resistance and low temperature resistance. It can withstand high temperature to 300°C in a short time, and generally can be used continuously between 240°C and 260°C. It has remarkable thermal stability. It can work at freezing temperature: work without embrittlement, and does not melt at high temperature , To ensure the normal use of high-temperature cables.
3. Sliding property, PTFE coating film has a low friction coefficient. The friction coefficient changes when the load is sliding, but the value is only between 0.05-0.15.
4. Moisture resistance, the surface of the PTFE coating film does not stick to water and oil, and it is not easy to stick to the solution during the production operation. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime, saving man-hours and improving the working efficiency of high-temperature cables.
5. Wear resistance, with excellent wear resistance under high load. Under a certain load, it has the dual advantages of wear resistance and non-sticking.
6.Non-sticky, almost all substances do not stick to the PTFE film. Very thin films also show good non-stick properties.
