I. Overview
The LZZBJ9-36/250W1-2 series current transformer is suitable for current and energy measurement and relay protection in AC lines with rated frequency of 50, 60Hz, rated voltage of 35kV and below indoor devices.
The LZZBJ9-36/250W1-2 series current transformer is a fully enclosed and maintenance free product made by one-time casting of epoxy resin. It has the advantages of strong short-circuit resistance and high accuracy.

Structure Introduction
The primary and secondary coils of LZZBJ9-36/250W1-2 series current transformers have a chain structure,. The metrological grade iron core is made of ultrafine crystalline alloy, and the protective grade iron core is made of high-quality silicon steel sheets rolled. The secondary wires are evenly wound on the iron core. The primary coil is made of high-quality soft copper strip or glass wire enameled wire.
The casting body is fixed on the installation base with bolts. A nameplate is affixed to the casting body. There are four screw holes on the bottom plate for users to install and use. There are dedicated grounding bolts on the base plate.
