LZZK series card type zero sequence current transformerDetailed product description：

The LZZK series card type zero sequence current transformer is suitable for zero sequence overcurrent protection and small current grounding line selection devices in cable lines of AC power systems. The aperture for cable penetration is φ 100mm, φ 110mm, and φ 120mm.
This series of zero sequence current transformers is made of high-quality imported silicon steel sheets and nickel iron high permeability alloys processed by special technology to produce a ring-shaped iron core with 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 LZZK series card 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.
