Description
The LJH-SJQ 24KV unscreened separable connector is designed with a surge arrester. In addition to shape, the separable connector is almost consistent with the LJK-1 24KV/630A unscreened rear connector.
This cable connector enjoys lots of superiorities. It is configured with anti-explosion device, automatic separating unit and pressure release device which functions at fault starting current of 800A-16kA.
Besides, this unshielded connector with surge arrester is also fitted with nonlinear resistance card, thus possessing low residual voltage, rapid response, high stability of steep wave and many other remarkable electrical properties. Hence, this unscreened separable connector can provide security overvoltage protection for transformers, switchgears and cable branch boxes.
Reference Standards
The 24KV unscreened separable connector is totally in compliance with EN50180, EN50181 and DIN47636 standards.
