The installation of 11kV Cold Shrinkable 3Cores Straight Through Joint Kits is cold shrinkage construction, in the process of construction as long as the plastic wire core of the cable can automatically complete the contraction, without heating, this process is simple and practical, relative to the installation of heat shrinkage cable to eliminate the phenomenon of uneven shrinkage of insulation tube. HUAYI CABLE ACCESSORIES Co.,Ltd. 11kV Cold Shrinkable 3Cores Straight Through Joint Kits is sold all over the world.
1.Product Introduction
Rubber is known to have "elastic memory" properties, like a spring. Such as our 11kV Cold Shrinkable 3Cores Straight Through Joint Kits, Cold shrinkage technology, also known as pre-expansion technology, the elastic rubber in the elastic range of pre-support, set into the plastic support strip to be fixed. When installing, as long as the support strip is removed, the elastic body rapidly shrinks and tightens on the cable body. The cold shrinkage products manufactured by our company are all bonded with special sealing adhesive to make the overall sealing and avoid operation accidents caused by atmospheric environment. The silicone rubber used for raw materials has excellent insulation and high resilience, and will not cause electrical breakdown due to the breathing action of the cable during operation after installation. The products are widely used in electric power industry, communication industry, military industry, metallurgy, coal mining, petrochemical industry and other fields.
The scope of use of the 11kV Cold Shrinkable 3 Cores Straight Through Joint Kits is suitable for 8.7/10kV, 8.7/15kV XLPE, Three Cores power cables. And the installation environment of the 11kV Cold Shrinkable 3 Cores Straight Through Joint Kits should be dust-free, with a temperature above 0℃, and a relative humidity of 75% or less. The 11kV Cold Shrinkable 3 Cores Straight Through Joint Kits Installation acceptance test standards and operation supervision shall be carried out in accordance with relevant regulations.

5.Product Qualification
Cold shrinkage cable accessories is the use of elastomer materials (commonly used silicone rubber and ethylene propylene rubber) in the factory injection vulcanization molding, and then through expanding, lined with plastic spiral support to form a variety of cable accessories. During field installation, these preexpansion pieces are put on the treated cable ends or joints, and the plastic spiral strips (supports) of internal support are drawn out and pressed on the cable insulation to form cable accessories. Because it is at room temperature by elastic shrinkage force, rather than like heat shrinkage cable accessories to heat shrinkage with fire, so commonly known as cold shrinkage cable accessories. The product is waterproof, stress control, shielding, insulation in one, can be used in a variety of harsh environmental conditions for a long time. Widely used in Electric Power Industry, Petroleum Industry, Chemical Industry, Metallurgy, Railway, Port, Construction and other fields.
