Style 3367 / 3135 / 3139 / 3143 200°C silicone wire is a single-core high-temperature wire family for equipment that requires flexible routing and silicone insulation performance up to 200 °C. The styles cover 300 V and 600 V requirements with differing insulation thicknesses.
Key Features
- Continuous operating temperature from -60 °C to +200 °C.
- 300 V option in style 3367 and 600 V options in styles 3135, 3139, and 3143.
- Silicone rubber insulation with stated resistance to thermal shock and UV.
- Bare, tinned, nickel-plated, and silver-plated conductor options listed across the style family.
- Source data identifies UL 758, CSA C22.2 No. 210, horizontal flame test, FT2, and halogen-free references.
Applications
Designed for electrical heating appliances, rotating machines, lighting, and industrial wiring in hot environments.
