Product Description

Product Name

outdoor terminals for cross-linked polyethylene insulated power cables with liquid-filled insulating porcelain bushings

Application areas

Mainly used in high-voltage AC power transmission, connection of high-voltage power cables to electrical equipment or overhead lines, outdoor terminals of 66kV, 110kV, 138kV, and 220kV cross-linked polyethylene insulated power cables with liquid-filled insulating porcelain bushings.

Product Description

The terminal stress cone is injection molded from imported ethylene propylene diene monomer (EPDM) rubber and is held in place by a spring cone support. The stress cone cover structure isolates the stress cone from the insulating filler, overcoming the defects of elastic relaxation caused by material aging and poor contact between the stress cone and the outer semiconductive layer of the cable, thus ensuring the long-term stable operation of the terminal.
The terminal adopts a multi-layer sealing structure to prevent water seepage, oil leakage and other phenomena during operation;
The terminal bushing adopts a large and small umbrella skirt structure, which has good anti-flashover characteristics;
The ceramic sleeve is made of high-strength inorganic materials and has good weather resistance, anti-leakage, electro-erosion resistance and water-repellent properties.
