    High Temperature Electrical Cable

    SB/Silabraid Silicone Rubber Braided Cable – Class H 180°C, 1.1kV
    Flexible Tinned Copper Cable with Silicone Rubber Insulation & Silicone Resin-Varnished Fibre PET Braid

    SB/Silabraid Silicone Rubber Braided Cable is a premium Class H (180°C) flexible electrical cable designed for demanding industrial applications requiring excellent heat resistance, flexibility and long-term reliability. Manufactured with a Class 5 tinned copper conductor, silicone rubber insulation and a protective silicone resin-varnished fibre PET braid, it provides dependable performance in high-temperature environments where standard electrical cable is unsuitable.

    Rated for continuous operation from -60°C to +180°C with a 1.1kV AC voltage rating, SB/Silabraid is commonly used for motors, generators, transformers, renewable energy equipment, switchboards and electrical control systems. Its highly flexible construction also makes it ideal for starter coil to junction box connections on medium-voltage motors and generators.

    Common Applications
    • Medium-voltage motors and generators
    • Starter coil to junction box connections
    • Transformers
    • Wind energy systems
    • Solar inverters
    • Electrical cabinets and switchboards
    • High-temperature industrial wiring
