Product Description

LZZBJ9-12 Cast Resin Insulated Current Transformer Instrument Transformer

Introduction
This series are used for current and electric energy measurement, relay protection, in the power system with
rated frequency of 50Hz or 60Hz, rated voltage of 10KV.
This series are fully enclosed structure molded by electrical special epoxy, with excellent insulation and eletrical
performence, moisture resistance. The series are compact in structure, small and light, long in creep distance
and easy to clean. There is a junction box on secondary wiring. And the 8 mounting holes in the bottom are for
installation.

Feature
1. Epoxy resin cast fully enclosed post type
2. Suitable for rated voltage 10kv and below 50Hz power system and equipment
3. Used for current measurement and protection
4. It is of small size and easy installation
5. Primary side is P1, P2; 1S1, 1S2 of secondary side are for measuring and 2S1, 2S2 of secondary are for
protecion
