High Voltage Cable Accessories 66-220kV for Power Substations and Industrial Applications

Our high voltage cable accessories are designed for 66-220kV power transmission systems, suitable for cross-linked polyethylene (XLPE) insulated power cables from 240-3000mm². These products are widely used in power substations, large-scale industrial plants, and coastal areas where reliable power transmission is critical.

The main features include monolithic prefabricated structure combining insulation, shielding and stress cone in one piece. The stress cone is manufactured using imported liquid silicone rubber injection molding technology, ensuring long-term stable holding force and excellent electric field uniformity. The compact design offers small size, light weight and easy installation.

All products undergo rigorous testing including routine tests, sample tests, type tests and pre-qualification tests according to international standards. The accessories are protected by insulated, magnetically isolated metal protection boxes with superior mechanical properties and sealing performance.

Key electrical performance parameters include excellent partial discharge characteristics, high power frequency withstand voltage capability, and reliable sealing performance. The products are suitable for various environmental conditions including direct burial applications.
