LZZBW-36W3 current transformer adopts outdoor epoxy resin casting and belongs to support type full-closed structure. The product can be made four secondary windings，each winding can be tapped to realize three ratios with large external insulation creep distance, withstanding dirtiness and ultraviolet radiation. Be suitable for matching with 36kV (Up to 40.5 kV) outdoor for measuring electric energy, current and protective relaying.
Main technical parameter
1. Rated voltage: 30 kV or 33 kV or 34.5kV or 35kV etc
2. Rated secondary current:5Aor1A
3. Rated insulation level: 36/70/170 kV (40.5/95/200 kV)
4. Standards: IEC60044-1.2003 Part 1: Instrument transformers-Part1: Current transformers
