LZBW-10 series current transformersDetailed product description：

The LZBW-10 series current transformer is a dry-type outdoor device suitable for current and energy measurement and relay protection in AC lines with a rated frequency of 50Hz and a rated voltage of 10kV and below.

Structure Introduction

The LZBW-10 type transformer is modified based on the crude oil immersion transformer. The main insulation is made of epoxy resin casting, and the entire transformer body is installed in a box and sealed. The first and second output terminals are respectively led out by insulated porcelain sleeves, and there are four slots on the bottom plate for installation and fixation. According to user needs, when the current is below 200A, a single insulated porcelain sleeve can be used to lead out the primary wire and divide it into P1 and P2 terminals, or two insulated porcelain sleeves can be used to lead out the P1 and P2 terminals. At the same time, when the current is below 200A, it can be made into a dual ratio (such as 75-150/5A). The product not only has the advantages of high temperature resistance, aging resistance, strong antifouling, but also solves the problem of oil leakage of crude oil immersed products.
