SIHF/P braid armoured multicore 180°C silicone flex

SIHF/P braid armoured multicore 180°C silicone flexible cable is designed for power and control use. Suitable for high or low temperature applications where traditional PVC materials would become brittle. If the cable burns an insulating layer of silicone dioxide will remain, rendering the cable short circuit proof.

These SIHF/P armoured multicore silicone cables are halogen free and suitable for use at constant temperatures up to 180°C. The galvanised steel wire braid (GSWB) armour provides protection against mechanical damage. 

The silicone compound used is more accurately called polymerizedsiloxane or polysiloxanes. It is resistant to vegetable and animal fats, to many types of oil and many diluted acids. There is no decomposition on exposure to alcohol or alkaline solutions. 

The term halogen free (interchangeable with the term zero halogen) guarantees that if burnt the cable will produce less than 0.5% HCL (hydrogen chloride) emissions. This provides increased safety in the case of a fire. For a more in-depth explanation of halogen free & zero halogen properties please see our LSZH Control Flex front page.
