GCB-IT series 35kV cold shrink indoor terminalDetailed product description：

GCB-IT series 35kV cold shrink indoor terminal

Product features:
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. 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.  
3. Advanced production technology
All use gas expansion to effectively prevent creepage paths from forming inside the product cavity.
4. Advanced structural design
Optimize the design using computational software, with reasonable insulation and sealing design.
5. Widely used
The material is resistant to pollution, aging, and has good hydrophobicity, with superior cold resistance, especially suitable for high-altitude areas, cold areas, humid areas, salt spray areas, and heavily polluted areas. When installing, do not use open flames, especially suitable for flammable and explosive places such as petroleum, chemical, mining, etc.
6. 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:
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; Using a conical stress body to control stress at cable terminals, ensuring uniform distribution of electric field at cable terminals.
