LZZW-36 Outdoor Current Transformer
Description
Epoxy resin casting insulation and fully enclosed support construction, encloses the primary & secondary windings and annular core in the epoxy resin casting body. The product has large periphery insulation creepage distance, withstanding dirtiness and dampness. Be suitable for measuring electric capacity, current and protective relaying in the power system of 36kV (Up to 40.5 kV).
Main technical parameter
1. Rated voltage: 30 kV or 33 kV or 34.5kV or 35kV etc
Double ratio
Remarks: Upon request we are glad to offer transformers according to other standards or with non-standard technical specs.
