LV Iinsulated current transformer

General:

The transformer is indoor type current transformer, suitable for current measurement, electric energy measurement or relay protection in circuits with rated frequency of 50Hz and rated voltage of 0.5kV or below, and the measuring and protection devices are isolated from high voltage. Products comply with :GB/T 20840.2 standard.

Key Feature

• The conventional transformer is composed of coil, mounting plate and insulating material (resin casting filler).

• In addition to these, the Type II (new) transformer also adds a shell coil which is first installed in the shell and then sealed by resin pouring filler.

• Both are dry insulated.

• The label of the Type II (new) transformer can either be laser etched on the housing body, or aluminum labels can be inlaid on the housing.

• One bus goes through the window.

• The transformer is bolted to the mounting plate.
