12/630-25kA SF₆ Ring Main Unit Passes Key Electrical Tests

Xing Electric Appliance Group’s 12/630-25kA SF₆ Ring Main Unit has successfully passed short-time and peak withstand current tests as well as grounding switch short-circuit closing tests at Guang’an Electric Testing Center (Guangdong).

The unit maintained structural stability under high current impact, with internal conductive and insulating components effectively handling thermal stress, ensuring reliable operation under extreme conditions.

The grounding switch closed smoothly in 7 consecutive tests, with no arc re-ignition or contact welding, providing effective circuit control during fault conditions.

These results demonstrate that the 12/630-25kA SF₆ Ring Main Unit meets high performance standards and sets a new benchmark for SF₆ ring main unit technology, offering a reliable, high-quality solution for modern power distribution systems.
