LZZB7-35W2(A) series current transformersDetailed product description：

The LZZB7-35W2 (A) series current transformer is an epoxy resin cast insulation fully enclosed product, suitable for current and energy measurement and relay protection in indoor power lines and equipment with a rated frequency of 50Hz or 60Hz and a rated voltage of 35kV and below. The product complies with the standards of IEC44-1:1996 and GB1208-1997 "Current Transformers".


Structure Introduction
The LZZB7-35W2 (A) series current transformer is a fully enclosed structure, with the primary and secondary windings and iron core cast in epoxy resin, which is resistant to pollution and moisture. This product has two different structural dimensions, among which LZZB7-35W2 is a substitute for the semi enclosed product LCZ-35.
