Flame-retardant and Heat Resistant Power Cable :
Features and Applications:
This product is used in cable hanging, drawing and installation for field line, electric appliance and instrument electronic equipment and automation devices for electric power,chemical, metallurgy, open port, goods yard and mine etc.As silicone rubber and butyronitrile PVC from GE company of USA and domestic modified Model 271 silicone rubber are respectively used in insulation and coating materials, the product is especially soft, easily folded and movable, smoothand unbending, It is one of products solemnly recommended by our company Henan Jiapu Cable Group.
Executive Standard
IEC245-3 standard.
Operational Performances
