Features

1. The termination stress cone is injection molded with imported EPDM rubber, supported by a spring cone, and isolated from the insulation filler by a stress cone cover structure, overcoming the drawbacks of elastic relaxation caused by material aging and poor contact between the stress cone and the outer semiconducting layer of the cable, which ensures long-term stable operation;

2. The termination adopts a multi-layer sealing structure to prevent water and oil leakage during operation;

3. Various size of rain shed structure design, has good anti fouling and flashover characteristics;

4. The Outer insulation is made of silicone rubber, it has outstanding properties of anti-pollution flashover, anti-UV, anti-aging and anti-explosion while it weighs only 50% of porcelain termination at equivalent voltage level, which provides a more convenient installation

5. Type Test according to IEC60267, IEC60840
