Heat Shrink Wrap-around Sleeve / GWCS 500&1000
Heat Shrink Wraparounds Composite Sleeves
Features
• Made from composite materials: PE with fibers integrated
• Type 500 also with aluminium layer which provide a fast and simple way to seal telephone cable splices in non-pressurized cable
• Type 1000 sleeves without aluluminium layer but more stronger both for thickness of sleeves and density, which suitable for repair of all types of non-pressurized cable: aerial, buried or ducted, non-filled or jelly filled with polyethylene or metal jackets
