Voltage level:AC 35kv, 10kv, 6kv, 3kv
High accuracy, light weight, easy to install and anti-tamper.

1. General

AC immersed outdoor type high-voltage power metering box (called combined transformers without metering) is use to measurement the power consumed in high-voltage electrical network. It suitable for 50Hz and 60Hz three phase AC 35kv, 10kv, 6kv, 3kv power system. High accuracy, light weight, easy to install and anti-tamper, welcome by the majority of the electricity sector, enhance supply management. This product replaces the previous combination of conventional oil-immersed transformers, can be installed in any direction, long-term maintenance-free and oil-free.

Current transformer, voltage transformer and metering box compose this product, inside the transformer there are 2 independent voltage transformer and current transformer installed in A, C phase. The cable boxes are outside of the of them.

The Core using epoxy resin casting, one-piece combination, easy to replace. Shell is steel drums, avoid the sun’s ultraviolet rays burning. Double ratio and triple ratio both can be control in the second terminal.
