High-temperature cables are cables with conductors made of multiple strands of soft copper. Heat-resistant and high-temperature wires and cables are generally determined by two needs. The first is that the ambient temperature of the wire and cable is high, and the cable can normally transmit signals or electricity under high temperature for a long time; the second is the power transmission cable, which mainly aims to increase the current carrying capacity.
1. Corrosion resistance: Polytetrafluoroethylene is widely used in high-temperature and high-viscosity industries. Even the super strong acid, fluoroantimonic acid, can be stored in it.
2. Heat resistance: Polytetrafluoroethylene coating has excellent heat resistance and low-temperature resistance. It can withstand high temperatures up to 300℃ for a short time, and can be continuously used between 240℃~260℃, with significant thermal stability. It can work at freezing temperatures without becoming brittle, and does not melt at high temperatures, ensuring the normal use of high-temperature cables.
3. Sliding property: Polytetrafluoroethylene coating has a low coefficient of friction. The coefficient of friction changes when the load slides, but the value is only between 0.05-0.15.
4. Moisture resistance: The surface of the polytetrafluoroethylene coating does not stick to water and oil, and it is not easy to stick to the solution during production operation. If a small amount of dirt is attached, it can be easily removed by simply wiping it. Short downtime saves labor time and improves the working efficiency of high-temperature cables.
5. Wear resistance: Under high load, it has excellent wear resistance. Under a certain load, it has the dual advantages of wear resistance and non-stickiness.
6. Non-stickiness: Almost no substances adhere to the polytetrafluoroethylene coating. Even a very thin film shows good non-stick properties.
