heat shrinkable joint closures for telecom cables

Product Description

We are the leading professional manufacturer of heat shrinkable joint closures for telecommunication cables in China. RSBJ jointing closures are fiber reinforced jointing closures and widely used in non-pressurized telephone network for the protection of cable joints. RSBJ is based on a unique glass fiber reinforced heat shrinkable composite material. This new revolutionary material offers extra ordinary mechanical and environmental protection. Its reinforced material structure has an excellent split resistance during installation and superior mechanical toughness. An integral metal layer which shrinks with the sleeve protects the joint from moisture vapour transmission. The inner coating of hot melt adhesive guarantees a watertight and secure bonding to plastic and metal-sheathed cables. The white line inside of the trajectory and the temperature-sensitive paint on the sleeve can lead a good and right operation. The reinforced branch-off and straight closures have been developed to meet the increased demand in cable networks.
