RSBJ550 92/25-500 Heat Shrinkable Copper Splice Closure

Heat shrink copper splice closure is also called heat shrink closure, heat shrink splice closure, heat shrink copper splice closure.  It is a system designed to provide excellent split resistance, environmental and mechanical protection for cable jointing, splicing and connections. They are typically used in telecommunication applications to protect splices in underground or aerial cables.

There are two main types of heat shrinkable closures:

• Non-pressurized Heat Shrinkable Closures: Benchmarks can be Raychem/Tyco/Commscope XAGA 500, 530 and 550. These heat shrinkable closures are designed for use in applications where there is no internal pressure on the cable. They are typically made from a fiber-reinforced heat shrinkable sleeve with a hot melt adhesive lining. When the sleeve is heated, the adhesive melts and forms a seal around the cable connection to provide tightness.
• Pressurized Heat Shrinkable Closures: Benchmarks can be Raychem/Tyco/Commscope XAGA 1000. These heat shrinkable closures are designed for use in applications where there is internal pressure on the cable, such as underground vaults. They are typically made from a fiber-reinforced heat shrinkable sleeve with a metal canister or a combination of sleeve, buttress, and canister. The canister provides additional strength and helps to prevent the closure from bursting under pressure.

XAGA 550 fiber reinforced heat shrink splice closure system is designed to provide excellent split resistance, environmental and mechanical protection for cable joint. The fiber reinforced heat shrink sleeve is made from a composite laminate material consisting of reinforcing glass fibers, polyethylene layer, an aluminum layer for moisture vapor transmission and hot melt adhesive on the inner surface. The heat shrink sleeves are supplied in wraparound form along with stainless steel channels to make the sleeves cylindrical prior to shrinkage. The outer surface of the sleeves are coated with temperature indicating paint which changes color to indicate optimum shrinking. On application of heat, the inner adhesive layer melts and bonds to the cable surface to provide a waterproof seal.

Features:

• Heat-shrinkable composite joint closure system for environmental and mechanical protection of joints in the unpressurised telephone network: aerial, buried or ducted, non filled or jelly filled, with polyethylene, lead, steel or aluminium sheaths.
• Composite structure of the reinforced Rayfort sleeve offers an excellent resistance to mechanical abuse during and after the installation.
• Integrated moisture barrier completely reconstitutes the cable sheath over the total splice area.
• Hotmelt adhesive forms a watertight seal to the cable sheath.
• A metal canister shapes and mechanically protects the splice bundle.
• Up to 3 cables at each end can be accommodated using three finger clips with hotmelt adhesive.
• Installation indicators: heat sensitive paint and adhesive flow, white line
• Extended size range can accommodate splices up to 3600 pair with any connector type.
• Unlimited shelf life.

Heat shrinkable closures are a relatively simple and easy to use way to protect cable connections. They are available in a variety of sizes to accommodate different cable diameters. When choosing a heat shrinkable closure, it is important to consider the size of the cable, the type of application, and the environmental conditions.
