Silicone wire uses silicone rubber as insulation, with a conventional temperature rating from -60℃ to +200℃, and can withstand short-term higher temperature shocks. Fahua Cable's UL3135, UL3122, and VDE H05S-K series silicone wires are designed and certified to the 200℃ rating, remaining flexible down to -60℃, suitable for high-temperature industrial equipment, hot zones of household appliances, and wiring inside new energy vehicle cabins.

The typical temperature range of silicone wire is -60℃ to +200℃, making it one of the highest-temperature-rated conventional categories among mass-produced wires, without hardening at low temperatures or melting at high temperatures.
