Characteristics: 1) It does not require heating by flame or special tools. As long as we pull out the plastic string from silicone rubber tube, the silicone rubber will be tightly shrunk in the needed position 2) Reliable insulation and high-recovery elasticity; we have adopted imported liquid-silicone-rubber, such that the cable will keep its radial pressure permanently, making the contact surface closely jointed together, thus no flash-ores occur, nor strike as well 3) Superior hermetic sealing: Silicone rubber with hermetic and hydrophobic performance; these will be no serious fault due to environmental causes 4) Easy/convenient installation: By enlarging the dimension of stress-cone, larger tolerance will be permitted and faults due to installation are reduced to a minimum 5) Wide application: Possessing a series of superior performances such as antipollution, long usage, hydrophobic, cold-withstanding, etc. The cold shrinkable accessories can be widely used in various regions, especially suitable for high level region, cold weather region, high-humidity region, salt-fog region and high-polluted region etc 6) Excellent Appearance: With longer cold shrinkable tube, no commissural line. And smooth surface. 7) Strong waterproof properties Can be used as 1-core and 3-core Sold by set, with the material in the set, it can be installed easily. Cable conduct cross section:25 - 800mm2
