Sichuan Zhongguang Lightning Protection Technologies Co LtdCompany obtained two patents for surge protective devices, including a varistor failure protection solution and an innovative pluggable SPD structural design.

Zhongguang Lightning Protection announced on September 17 that the company recently obtained two patent certificates issued by the National Intellectual Property Administration. One is for a surge protective device, providing a varistor failure protection solution. When the varistor fails, the SPD can act within a short time and form a safe short-circuit path, causing the front-end protective device to trip quickly and thereby protect the downstream circuit. The other is for a base body and a pluggable surge protective device, providing an innovative structural design that effectively increases creepage distance and clearance without increasing volume, to meet the application requirements of high voltage, large current flow, and miniaturization. In the first half of 2026, Zhongguang Lightning Protection achieved revenue of 267 million yuan and net profit attributable to the parent company of 12.05 million yuan.
