LFSB-10 type current transformerDetailed product description：

The LFSB-10 indoor/fully enclosed/all condition/dry-type 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 10kV and below. This type of current transformer has a small volume, light weight, superior insulation performance, high precision, and high dynamic and thermal stability multiple. The product complies with the standards of IEC44-1:1996 and GB1208-1997 "Current Transformers".

Structure Introduction
This type of 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.
