The 10KV three-core heat shrink indoor terminal is a high-performance heat shrink accessory designed for the cable terminal section of high-voltage power systems. Using advanced heat shrink materials and technology, it provides excellent electrical insulation and mechanical protection, ensuring the cable operates stably in high-voltage environments. This product not only boasts outstanding voltage withstand capabilities but also endures frequent load cycling and impulse voltage tests, ensuring its long-term, reliable operation.
The 10KV three-core heat shrink indoor terminal has a power-frequency withstand voltage of up to 39KV and has undergone rigorous impulse voltage testing, withstanding 105KV without flashover or breakdown. In partial discharge tests, the discharge at 10KV is only 3PC, demonstrating excellent partial discharge control. Additionally, it has strong load cycling capabilities and can undergo three cycles of heating and cooling at conductor temperatures without performance degradation.
