The LXK series zero sequence current transformer is suitable for zero sequence overcurrent protection and small current grounding line selection devices in AC power systems, distribution lines, AC generators, motors and other electrical equipment. The aperture range for cable penetration is from 80mm to 240mm.

The LXK (C) series zero sequence current transformer uses imported high-quality silicon steel sheets and is made 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 small space.

The LXK series open type zero sequence current transformer consists of two semi-circular rings, which can be installed on connected cables, making it simple, fast, harmonious and beautiful. The LXK series through type zero sequence current transformer will be pre fixed on cable penetrations of electrical equipment such as ring network switchgear cabinets. During installation, the cable head will be made by threading the cable through the transformer.

The rated current, accuracy level, and rated load are shown in the following table:
