Style 3253 / 30144 / 30145 250°C silicone wire is a single-core high-temperature wire family for internal equipment wiring where sustained heat resistance and flexible routing are required. The family combines a metallic conductor with silicone rubber insulation and offers 300 V, 600 V, and 1000 V style options.
Key Features
- Continuous operating temperature from -60 °C to +250 °C.
- Silicone rubber insulation with stated resistance to thermal shock and UV.
- Style-based voltage options: 3253 at 300 V, 30144 at 600 V, and 30145 at 1000 V.
- Available with bare copper, nickel-plated copper, or nickel conductor options according to the technical data.
- The source data identifies UL 758 approval, horizontal flame testing, FT2 flame rating, and halogen-free material performance.
Applications
Suitable for household electrical heating appliances, rotating machines, lighting equipment, and industrial wiring in hot atmospheres.
