Cold cable accessories based on user needs, can complete the insulation of the cable shielding layer, straight. Conductors in the cable joint use hex die according to the rules of the tonnage, pressure to small touch resistance, strong mechanical strength, fully satisfied line normal operation and short circuit operation requirements. Cold cable accessories excellent physical and mechanical features: cable accessories general silicone rubber tensile and tear strength is low, if you want to progress of silicone rubber tensile can tear resistance, elongation reduces, the hardness will increase; And used to make the cold electric cable accessories of silicone rubber, demand together with high elongation strength and low hardness and high tensile resistance to tear strength, elongation is 800%, shaw A hardness, tensile strength reached 45 degrees 10 mpa, reach 30 kn/m. The cold resistance of cable accessories goods tracking ability should arrive 1 a3. Level 5. Usually progress of silicone rubber resistant to tracking ability is increased a lot of aluminum hydroxide; But, a lot of increase after these packing, is bound to progress the hardness of silicone rubber, the lower the elasticity. Company has declared open advanced technology in does not affect the silicone rubber hardness, elasticity, and expand to premise, the resistance to tracking to reach 4. Level 5. And this technology can also make silicone rubber has a strong hydrophobic, rain in the production of cold shrink cable termination, neither from film, also won't form a conductive path; It can wash away the appearance of the ash layer. Namely can obviously progress cold cable terminal electric function, the use of heat shrinkable cable accessories and explore in a relatively short dark group, finish relatively large scale leakage interval.
