Straight - Through Zero Sequence Current Transformer 11KV New Magnetic Material
New Magnetic Material Straight-Through Current Transformer for 11KV
LZCG530-10 Straight-Through Current Transformer is suitable for current measurement and microcomputer protection of electrical equipment in 10KV and 35KV AC power system. It is widely used in not only compact fully insulated ring network switchgears such as ABB-Safe Ring/Safe Plus, Unstitch, Schneider RM6, SM6, Siemens 8DJ10/8DH10, Simosec, FBX, Fluokit, Omar Garbo GA, GAE; SEL TPS(Q); VEI Unifluorc; Eaton SVS/12 ring network, but also cable distribution boxes because of its small size, light weight, operable and convenient installation. It is very convenient that the transformer can be directly installed at the inlet and outlet cables.
