LDJ1-35H/300 series current transformersDetailed product description：

The LDJ1-35H/300 current transformer is an epoxy resin cast insulation fully enclosed product, suitable for use in power systems with a rated frequency of 50Hz or 60Hz and a rated voltage of 35kV and below, for energy metering, current measurement, and relay protection. This product complies with the IEC60044-1 and GB1208 "Current Transformers" standards.

Structure Introduction
The LDJ1-35H/300 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 φ45、φ70。
