Electrical network surge arrester KAD-GZF

Based on the "Supplementary Documents for Secondary Lightning Protection and Network Isolation Renovation in Substations"-Transportation Equipment announcement No. 240 and "Opinions on Optimizing Technical Solutions for the Secondary System of Traction Substations Against Strong Electricity Intrusion"-Transportation equipment announcement No. 325 standard, integrated lightning protection screen is carefully designed and professionally manufactured. In line with lightning protection design specifications, it’s a centralized SPD independent screen cabinet designed to prevent strong electricity intrusion in the secondary system of traction substations. The integrated lightning protection screen is installed at the border between the lightning protection LPZO zone and the LPZI zone, and is an important centralized protection for the power supply and signal sending (receiving) of the indoor equipment in the lightning protection of the outdoor equipment. It overcomes the problems of the existing lightning protection equipment: does not meet the lightning protection specifications, the installation is scattered, the maintenance and monitoring are inconvenient, and the operation of the protected equipment is affected by the occurrence of heat and fire caused by aging failure. •KAD-GZF integrated lightning protection screen is applied to the lightning protection of the secondary system of the traction substation to prevent the intrusion of over-voltage and over-current, and it adopts an independent screen cabinet with centralized installation of SPD.
