The 10KV three-core heat shrink outdoor terminal is a cable terminal designed specifically for high-voltage power systems. This product uses heat shrink technology to provide reliable sealing and insulation protection for cable joints. It features strong voltage resistance, maintaining stability under high voltage and load cycling, ensuring the safe operation of power systems. It is especially suitable for outdoor environments, remaining stable under extreme conditions such as high humidity and high temperatures, and is widely used in power transmission and distribution systems.
The terminal has a power-frequency withstand voltage of 39KV and can operate continuously under this voltage. It also passes through three full cycles during load cycling. In addition, it has a strong ability to withstand impact voltage, capable of withstanding 105KV of impact voltage. The design also takes long-term withstand voltage into account, being able to maintain 52KV for 15 minutes without flashover or breakdown, ensuring the long-term reliability of power equipment.
