J-GCB2001,J-GCB2001K type 6~35kV cold shrink intermediate jointDetailed product description：

Product Features:
1. Excellent materials
Adopting imported liquid silicone rubber material, it has excellent electrical performance, strong resistance to leakage marks and corrosion. This material has the characteristic of "elastic memory", which can shrink back to its original position for a long time after expanding within the elastic range. Installed on the cable, it can still maintain a suitable radial pressure on the cable body, making the inner interface tightly connected and breathing with the cable, without causing electrical breakdown due to the breathing effect during cable operation. This ensures the reliability of the internal insulation.
2. Advanced production technology
All use gas expansion to effectively prevent creepage paths from forming inside the product cavity.
3. Advanced structural design
Optimize the design using computational software, with reasonable insulation and sealing design.
4. Widely used
When installing, do not use open flames, especially suitable for flammable and explosive places such as petroleum, chemical, mining, etc.
5. Excellent Quality:
a、 100% factory testing, 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
1. Widely used in harsh environments such as mines, underwater, cable tunnels, or directly buried soil.
2. Connect the two ends of the cable to form a cable line, while ensuring insulation and sealing of the cable.
