The NLS-10/3 10KV Cold Shrink Three-Core Indoor Terminals is a high-performance cable accessory designed for 10KV power systems, providing excellent electrical insulation protection. The rated voltage of the product is 10KV, and it has passed strict AC withstand voltage tests. It can withstand 10KV AC voltage, and during the 5-minute AC withstand voltage test, it can tolerate up to 39KV without flashover or breakdown, ensuring its reliability during operation. Additionally, the product has passed partial discharge tests, with less than 10pC discharge at 30KV, improving its operational stability. It also demonstrated excellent performance in the 15-minute DC withstand voltage test, with a value of 35KV and no flashover or breakdown.
The terminal head is typically 650mm in length but can be customized based on customer requirements, with options of 800mm, 1000mm, or 1204mm. It uses cross-linked cable heat-shrink technology and adopts a dual-grounding process, separating steel armor and copper screen grounding, making cable pretesting more convenient and efficient. The product also caters to oil-impregnated cables, with oil-sealing finger sleeves and an additional insulation finger sleeve at cable termination and branch points, ensuring safety and reliability.
