Description
1. The external insulation of this termination uses porcelain bushing insulating tube material, suitable for operation in coastal and heavy pollution areas. The insulation level, current-carrying capacity, operating temperature and other performance of this termination fully meet the requirements of the matching cable. 2. The stress cone of the termination is made of imported EPDM rubber by high-pressure injection molding, pressed tightly by a spring cone support, and a stress cone cover structure is adopted to isolate the stress cone from the insulating filler, overcoming drawbacks such as elastic relaxation due to material aging and poor contact between the stress cone and the cable's outer semiconductive layer, ensuring long-term safe and stable operation of the termination. 3. The porcelain bushing is made of high-strength high-voltage electrical porcelain, with good weather resistance, anti-tracking, erosion resistance and hydrophobicity. 4. The termination adopts a multi-layer sealing structure to prevent water seepage, oil leakage and other phenomena during operation. 5. The termination bushing adopts a large and small shed structure, providing good anti-pollution flashover performance.
Features
- 1. The external insulation of this termination adopts a porcelain bushing insulating tube material, suitable for operation in coastal and highly polluted areas. Its insulation level, current-carrying capacity, operating temperature and other properties fully meet the requirements of the matching cable. 2. The stress cone of the termination is molded from imported EPDM rubber by high-pressure injection molding, pressed tightly by a spring cone support, and a stress cone shield structure is adopted to isolate the stress cone from the insulating filler, overcoming drawbacks such as elastic relaxation caused by material aging of the stress cone and poor contact between the stress cone and the cable's outer semiconductive layer, thereby ensuring long-term safe and stable operation of the termination. 3. The porcelain bushing is made of high-strength high-voltage electrical porcelain, featuring good weather resistance, tracking resistance, electrical erosion resistance, and hydrophobicity. 4. The termination adopts a multi-layer sealing structure to prevent water seepage, oil leakage and other phenomena during operation. 5. The termination bushing adopts a large-and-small shed structure, providing good anti-pollution flashover performance.
