GCB-OT6~20kV Cold Shrink Outdoor TerminalDetailed product description：

GCB-OT6-20kV cold shrink outdoor terminal

1. Using a unique formula of highly elastic silicone rubber as insulation material, silicone rubber has many advantages as external insulation:
a、 The most resistant to suspended chemical pollutants, not easy to stick to dust, resistant to high temperatures, acid and alkali corrosion.
b、 Natural anti ultraviolet and anti-aging ability.
c、 Good insulation performance, difficult to generate conductive carbide channels, excellent anti creepage performance, and insulation regeneration ability.
d、 It is a hydrophobic substance that can maintain high surface resistance.
e、 Has hydrophobic recovery function.
2. Cold shrink installation method, easy to install:
Peel off the cable and fix the cold shrink end according to the specified size, extract the support strip and install it.
3. Advanced design technology:
a、 Constant and persistent radial contraction force, in close contact with the main insulation surface, does not cause insulation dead corners due to cable bending, solving the problem of water vapor penetration caused by cable breathing. Sealed and waterproof well.
b、 Without the use of open flames, there is no possibility of damaging the insulation of the cable body, insulation pipes, or other materials. There is no possibility of insufficient shrinkage leaving gaps that may cause internal crawling and electrical breakdown.
c、 Single body structure, with tight interface contact between stress tube, insulation tube, skirt edge, etc., can be completed in one go, making installation simple and reducing installation errors.
d、 Less tools are required, with complete accessories such as grounding springs and cleaning agents, and no need for a blowtorch.
4. Excellent Quality:
a、 100% factory inspection, stable quality.
b、 The permanent deformation rate is small, which can ensure high elasticity for a long time.
c、 The average service life is 25-30 years.
d、 All components have passed the authoritative testing conducted by the National Testing Center - Wuhan High Voltage.

Product Usage
Installed at both ends of the cable line, connecting the cable to the power grid or other electrical equipment while ensuring insulation and sealing of the cable; Intelligent control units are used to apply electrical stress to the insulation surface of the semi conductive shielding end of the cable, in order to control the distribution of electrical stress at the cable terminal and ensure even distribution.
