Dalian Xin’anyue Electric Power Equipment Co., Ltd. is one of the leading manufacturers and suppliers of lxz series zero sequence instrument current transformer in China. We are committed to providing high quality customized products with competitive price. Welcome to wholesale CE approved lxz series zero sequence instrument current transformer from our factory.
The LXZ series closed type zero sequence CT is specially developed for zero-sequence current detection and earth fault protection within AC power distribution systems. Manufactured by Dalian Xinanyue Electric Power Equipment Co., Ltd., this closed type zero sequence CT adopts an integrated non-split annular iron core structure. It belongs to the through-type design and requires cables to be threaded through the central window before commissioning, which helps deliver stable measuring accuracy with low magnetic leakage.
This closed type zero sequence CT can be matched with relay protection and fault line selection devices. It captures zero-sequence current signals accurately to realize leakage monitoring and single-phase earth fault protection for power cable circuits. Its iron core and secondary winding are vacuum encapsulated with premium epoxy resin inside the housing. The fully sealed casting structure provides reliable moisture resistance and excellent insulating performance. The product can sustain steady working performance during long-term continuous operation. Under standard indoor service conditions, frequent routine maintenance is not required throughout its whole service life.
