Cold effect, and ceramic powder heat-insulation chamber is combined, effectively cable is isolated with external heat and cold air, while increasing cable
Cold-resistant dynamics.
2, cable is consolidated convenient for staff when erecting cable by using cable sheath top installation link
It is fixed, and then ensure cable stability.
3, by using plastics plastic protective cover, be conducive to increase cable jacket defencive function, avoid being damaged by the external world
It is bad, and utilize conducting wire mounting groove, convenient for increase cable fastness so that connected between conducting wire it is even closer, cooperation silica gel lead
Backing, the heat generated when convenient for conducting wire working imports conducting wire mounting groove internal layer, and then disperses heat, ensures that conducting wire uses effect
Fruit.
