Product Description

JLSZY-10 integral casting high pressure dry combined transformer (integral casting high pressure metering box) is improved on the basis of similar products. It is suitable for rated frequency 50HZ and is an ideal replacement product for old oil-immersed metering box products. JLSZY-10 dry-type power metering box is composed of two single-phase fully insulated voltage transformers to form a three-phase "V" type connection, A and C phases are connected in series with two current transformers, and the rated voltage is 10KV. The outdoor power system is used in Active and reactive energy measurement, current transformer can be made into a multi-variable ratio structure, which brings convenience for future system capacity expansion. JLSZY-10 integral casting high-voltage dry-type combined transformer (overall casting high-voltage metering box) voltage transformer is made of outdoor epoxy resin vacuum casting with current resistance and aging resistance. Rainproof and dustproof, it is an ideal replacement product for urban and rural power grid transformation.
