The 10KV three-core heat shrink intermediate joint is a heat shrink accessory specifically designed for cable joints in high-voltage power systems. Using advanced heat shrink technology, this product provides reliable sealing and insulation, ensuring the safe operation of cable joints. It is particularly suitable for the intermediate joint section of power systems, offering excellent resistance to high voltage, impact, and partial discharge, ensuring the stability of the power system during prolonged operation.
This joint has a power-frequency withstand voltage of 75KV and has undergone rigorous load cycling and impulse voltage tests. It can withstand 45KV of conductor current during long heating and cooling cycles, while maintaining high stability. Additionally, it can withstand 108KV of negative pole voltage for 15 minutes without flashover or breakdown, significantly extending the service life and safety of the cable joint.
