Zero-sequence current transformer model LXK(C)-10/20 is applicable to zero-sequence overcurrent protection and small current grounding line selection devices for distribution lines, alternators, motors and other electrical equipment in AC power systems. Its cable through-hole diameter ranges from 80 mm to 240 mm.
Fabricated from high-quality silicon steel sheets via special processing technology, this zero-sequence current transformer features high accuracy and excellent accuracy limiting factor. The iron core and secondary winding are vacuum-cast with high-grade epoxy resin and enclosed in a flame-retardant housing. It boasts outstanding moisture resistance, stable performance and maintenance-free operation, along with compact size, light weight and small installation space.
The LXK series is an open-type zero-sequence current transformer composed of two semi-circular rings. It can be easily and quickly installed on pre-connected cables with a neat and aesthetic appearance. The LXC series is a through-type zero-sequence current transformer, which can be pre-fixed at the cable through-holes of ring main units and other electrical equipment. During installation, only cables need to be threaded through the transformer before cable terminals are fabricated.
