Special Wire and Cable > High & Low Temperature Resistant Cable
SiHF-C-Si Multi-Core Double-Sheath Shielded Silicone Rubber Cable
The SiHF-C-Si is a specialized multi-core silicone rubber cable rated below 180°C, engineered for high-temperature and low-temperature regions where cable insulation must tolerate significant temperature swings. Built with a tinned copper conductor, silicone rubber insulation, an inner silicone sheath, and a tinned copper wire braid shield (approximately 85% coverage) beneath a silicone outer jacket, it delivers reliable EMI shielding alongside excellent chemical and thermal resistance. Halogen-free and low-smoke, it is widely used in the steel production, aviation, shipbuilding, cement, glass, ceramics, and power generation industries, with dual CE and UL certification. For fixed installation only — not suitable for outdoor use.
