LDJ-35 series current transformersDetailed product description：

The LDJ-35 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".

The LDJ-35 series current transformer is a fully enclosed epoxy resin cast structure, with the P2 end of its primary winding directly serving as the static contact in the switchgear and equipped with a contact box. The cross-section of the static contact is divided into 80 × 10, 100 × 10, and 100 × 20 Φ45、Φ70。
