This series of metering boxes is an improved version of similar products, suitable for use as energy meters in outdoor AC power systems with a rated frequency of 50Hz and rated voltages of 10KV and 6KV. It is an ideal replacement for old-fashioned oil immersed products. This series of products is composed of two parts: a voltage current combination transformer and a measuring instrument box. The transformer is equipped with two independent voltage and current transformers divided into phases A and C. The outer wall of the combination transformer is equipped with active and reactive energy meters, as well as a joint junction box for testing. The meter box is used to prevent electricity theft during operation. The inner lining of the SZV1-10, 6, and 3 products is made of epoxy resin casting, and the outer shell is made of steel drums to avoid direct sunlight and ultraviolet rays from damaging the epoxy resin casting body.
