Cable Shrink Cable Accessories:
Cold contraction cable accessories is the use of elastomeric material (commonly used with silicone rubber and EPDM rubber) in the injection molding equipment vulcanization injection moldina, and then by expanding and lined with plastic spiral support composed of various cable accessories. When the installation is in place, the pre expansion parts are sheathed at the end or the joint of the processed cable, anc draw out the inner supporting plastic spiral strip (support).which is pressed on the cable insulation, Because it is at room temperature by elastic recoil force, rather than like heat shrink cable accessories to be used to heat the contraction, it is commonly known as the cold shrink cable accessories. Early cold contraction cable terminal head just additional silicone rubber insulation used and contraction parts, electric field treatment still use should stress cone type or stress zone around the package
Cold shrink cable accessories is a kind of new cable accessories which is prefabricated by adopting high elasticity sillicon rubber. This product is provided with special dieletric properly, the performance of resistance against tracking and coorrosion are strong, special water absorption rate, the constant shrinkage force, and it will not be insulation dead angle because the cable is bended. When is is installed at locale, it need not the heat source and spcial tool, so it improves the safety and reliability of product. This product has many other advantages else, such as excellent capability, nocel construction and convenient installation, when you use it, you only need to tear the plank, and then it will self reset. This product is widely used in the following fields. electric power, communication, war industry, metallurgy, miniing and petroleum chenical industry, etc.
Product Advantages:
1, widely used in low-voltage cable terminal processing;
2, to maintain a constant tightening force, with the cable with the breath, to ensure excellent interface characteristics.
3, advanced production technology, vacuum high pressure injection vulcanization molding. Internal structure perfect, no defects, in the 21KV below the Council put less than 1pc (8.7 / 15KV series).
4, without fire and special tools, and no gradually into the trouble, just gently extract the core rope, it will rely on their own elastic retraction, which closely close to the cable, each specification can be applied to a variety of cable Diameter, cable diameter compatibility.
5, the use of imported liquid silicone rubber to ensure excellent insulation and high flexibility, the installation of the cable body has always been to maintain a constant radial pressure, local discharge is small, with the cable body with the "breathing."
6, the terminal body with the cold shrink branch finger sets, cold shrink insulation tube and cold shrink terminal seal tube; intermediate connector with three waterproof sealing process to ensure that the annex excellent sealing moisture resistance.
7, the installation is simple, the operation of the technical dependence is low, easy to master. Cable pretreatment, the stripping distance is short, the installation space needs small. Grounding method using constant force spring fixed ground, no welding or copper tied line, more efficient, safe and reliable.
8, anti-pollution, anti-aging, good hydrophobicity, with excellent corrosion resistance, cold resistance and anti-ultraviolet, to ensure long-term use of stable performance. Especially for high altitude areas, cold areas, wet areas, salt fog areas and heavily polluted areas
