SiHF/GL-P Halogen-Free Steel Braided Silicone Multicore Cable | 0.6/1KV High-Temp Cable | -60°C to +250°C

SiHF/GL-P Halogen-Free Steel Braided Silicone Multicore Cable | 0.6/1KV High-Temp Cable | -60°C to +250°C

Product Overview

SiHF/GL-P Heat-Resistant Halogen-Free Steel Braided Silicone Multicore Cable is engineered for extreme thermal and mechanical stress environments. Featuring dual-layer silicone insulation, galvanized steel wire braiding, and glass fiber reinforcement, this cable operates continuously at 180°C (250°C short-circuit) while resisting oils, chemicals, and radiation. Compliant with DIN/VDE and IEC standards, it ensures signal integrity in power stations, steel mills, and mobile industrial equipment.
