Product Overview
The SiHF EWKF Silicone Multicore Heat-Resistant Cable is engineered for extreme industrial environments demanding exceptional mechanical durability, temperature resilience (-60°C to +200°C), and flexibility. Featuring proprietary EWKF silicone technology (Enhanced Tear/Cut Resistance + Softness), this cable eliminates the need for steel wire armor while outperforming traditional silicone cables in lifespan and reliability. Ideal for automation systems, machinery, and mobile equipment in high-stress sectors like steel, aviation, and heavy manufacturing.
Key Advantages vs. Standard Silicone Cables
50%+ Longer Service Life in abrasive/corrosive environments
Zero Steel Armor Required – 40% lighter & superior flexibility
Maintains Insulation After Combustion (SiO₂ ash layer)
Resists Mechanical Damage: Cutting, tearing, crushing
Simplified Installation in confined spaces due to high flexibility
