Dry GIS termination has composite structure of stress cone and epoxy sheath, making the surface of pre-fabricated stress cone clinged to the inner wall of epoxy sheath through spring assembly to reach reasonable interface pressure. It is suitable to be installed in gas insulated switchgear, GIS composite apparatus and transformer and so on, realizing the electrical connection between power cable and electrical equipment. Its installation interface size supply scope meet the specification of IEC60859.
Product characteristics
1.Injection-molded from high quality imported silicone rubber with high strength and elasticity and aging resistance, so it has good corrosion resistance, anti electrical erosion ability and hydrophobic property as well as excellent anti pollution flashover performance, still keeping good electrical properties under severely polluted condition.1. The termination is with dry structure, no need to fill with insulating oil or gas inside,so it is no pollution to the environment.
2. Stress cone compresses spring assembly, which is a design providing stress cone with constant and lasting interface pressure.
3. Compact structure, easy installation, reliable performance.
4. AII electrical connections and insulating components of termination are placed inside the metal casing, so it is full shielded and maintenance-free.
5. Suitable for indoor/outdoor using because terminations do not contact with the atmospheric environment so environmental condition, pollution grade and altitude are not restricted.
6. Stress cone and epoxy sheath will be 100% inspected according to the standard in the factory.
