China Best Current Transformer Relay Suppliers – JLSZV 10W phase three wire dry type metering box(outdoor epoxy resin casting) – Changan Group

Designation

overview 

This series of metering boxes is improved on the basis of similar products. It is suitable to be acted as power metering in the outdoor AC power system with rated frequency 50Hz or 60Hz, rated voltage lOkV and 6kV. It is an ideal substitute for the old type of oil-immersed products.
This series of products is composed of voltage and current combined transformer and measuring instrument box. The transformer is equipped with two independent voltage and current transformers in phase A and C. The outer wall of the combined transformer is equipped with active and reactive watthour meters, and a joint junction box for testing. When the transformer is running, it shall be covered by meter box to prevent electricity theft.
The inner core of the JLSG-10 is made of epoxy resin and the shell is made of steel drum, In order to avoid sunlight ultraviolet damage to the direct casting of hydrogen resin casting body.
