PVC or XLPE is the most common insulating material for control cables that are available in the market these days. However, these materials have several limitations. Low-temperature resistance of PVC and the rigidity of XLPE are just some of its limitations. Therefore, it is imperative that the wires which use these materials as insulation must not be exposed to such condition or event. This makes the wires incredibly limited in their applications.
To be specific, we have a customer whose equipment needs to be operated at 180℃ high temperature, so we suggested that they might need a customized silicone control cable. Silicone has a greater temperature resistance which can reach up to 200℃. This is because silicone is a thermoset material while PVC on the other hand is a thermoplastic material. This means that the silicone insulation will not melt when exposed to high temperatures. Should the insulation melt, the occurrence of short circuit is very likely, and this is a very dangerous occurrence. The technical requirements for the operator will be quite high, this is due to the customer's request for a smaller overall diameter of the custom control cables. After a series of thorough calculations as well as rigorous testing, the customer ended up becoming highly satisfied with the cable that we produced for them. It is these stories of harmonious collaboration with our customers that have allowed us to maintain a lasting business relationship with them that remains up to this day.
