Communication cold shrinkable tube
Mechanism of the product
Cold shrinkable tube is made of elastomer material (usually silicone rubber or epdm), which is vulcanized in the factory, then through the expansion, lined with plastic spiral support of the pipe.
During field installation, the predilator cover is placed at the treated joint, and the spiral plastic support strip for internal support is extracted, which is held tightly to the object by elastic retraction force
Good waterproof performance, easy installation and operation.When the installation, just pull out the plastic spiral support bar, will rely on their own elastic back to form a reliable radial pressure to hold the joint on both ends, so as to play the role of waterproof, leakproof, moisture-proof seal, convenient maintenance.
Material application, brand silicone rubber, ethylene propylene rubber, to ensure excellent insulation and high elasticity of the product, the cable body after installation to maintain a long time constant radial pressure, with excellent anti-pollution, anti-aging, water-repellent, corrosion resistance, cold resistance, anti-ultraviolet radiation and other properties.
Can be used in cold, wet, high altitude, heavy pollution areas.
