LZZB-27.5(GY) current transformer is single phase, dry, casting insulated and indoor current transformer. It is suited for measuring current and energy or relay protection in 220 KV, 50 Hz power system. The casting insulated structure can prevent core from rusting. The installing place should no gas, steam, sediment, dirt, explosive and erosive dielectric to effect the insulated performance.
