Silicone Rubber Insulated Cables High Temperature Cable13
Description

Product Overview:

The SIHF Multi-Core Silicone Rubber Heating Cable delivers reliable freeze protection and process heating in extreme environments. Featuring a robust silicone rubber construction and wide temperature range (-60°C to +180°C continuous; +250°C peak), it’s engineered for dry, humid, wet, and outdoor installations with low mechanical stress. Compliant with key EU safety and material standards.

Construction:

The cable’s high-performance design comprises three critical layers:

  1. Conductor:
    Fine-stranded, tinned or bare copper wire (to DIN EN 60228 Class 5). Ensures flexibility and optimal conductivity.

  2. Insulation:
    High-temp silicone rubber (Type 2GI1 per DIN VDE 0207-20). Provides electrical isolation and thermal stability.

  3. Outer Sheath:
    Abrasion-resistant silicone rubber (Type 2GM1 per DIN VDE 0207-20), red-brown. Protects against moisture, chemicals, and mechanical stress.

Engineering Guidelines:

  • Construction Advantage: Double-layer silicone (2GI1 + 2GM1) ensures durability in wet/high-heat environments.

  • Temp Limits: Continuous ≤180°C; ≤250°C (max 24h).

  • Bending Radius: ≥6 × cable diameter during installation.

  • Chemical Exposure: Verify silicone compatibility if used near aggressive fluids.

  • Identification: Red-brown sheath aids visual inspection.
