Switchgear are shielded bulkhead module blocks and the module assembly is combined with an earthquake-resistant function module blocks. The integrated technology of the module block and the aseismatic function is a double layers to attenuate and buffer the seismic motion and automatically release the arc high temperature and pressure gas that explodes in the event of an insulation deterioration or short circuit accident to the upper part of the switchgear to protect human and equipment. According to the IEC standard, it has received excellent product certification from Public Procurement Service, performance certification, SME technology market certification, innovative product demonstration purchase product confirmation, and disaster safety product certification. It has supply references such as IIAC($7,400,000), KDHC($6,200,000), IDC Center($5,200,000).
