66-500kV & 72.5-550kV Porcelain Cable Termination
72.5-550kV Porcelain Cable Termination
The Porcelain Cable Termination, is mainly used in the field of high-voltage power transmission, the connection between high-voltage power cables and electrical equipment or overhead lines.
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. Excellent weather resistance, leak resistance, electrical corrosion resistance, and hydrophobicity.
5. Type Test according to IEC60267, IEC60840
