AI Technical Summary

Technical Problem

Existing cables are prone to rapid melting and combustion of insulation and sheath under high temperatures in fires, leading to short circuits or open circuits in the conductors. They can also easily become fuel for fires, expanding the fire's range, and lack ceramic oxygen-barrier fire-resistant properties.

Method used

The system employs a combination structure of ceramicized silicone rubber fire-resistant jacket, rock wool rope jacket, and metal armor jacket. The ceramicized silicone rubber forms a hard ceramic shell at high temperatures, which, combined with the fire-resistant and heat-insulating properties of the rock wool rope jacket, and the flame-retardant and heat-insulating properties of the extruded flame-retardant material and the metal armor jacket, forms a multi-layered protection.

Benefits of technology

It effectively prevents flames from burning inward at high temperatures, slows down heat conduction, improves the fire resistance of cables, prevents the spread of fire, and ensures power support and signal transmission.
