LXK series card type zero sequence current transformer is suitable for zero sequence overcurrent protection and small current grounding line selection devices of cable lines in AC power systems. This series of zero sequence current transformers adopts high-quality imported silicon steel sheets and is processed into a circular iron core through special processes, which has high accuracy and accuracy limit coefficient. The iron core and secondary winding are vacuum cast with high-quality epoxy resin in a flame-retardant plastic shell, which is moisture-proof, stable in performance, maintenance free, small in size, light in weight, and occupies little space. The LXK series card type zero sequence current transformer consists of two semicircular rings and can be installed on connected cables, making it simple, fast, harmonious, and aesthetically. φ80φ100φ120φ140φ160φ180φ200φ240φ260φ300 Customized products can consult online customer service!
