Product Description

GENERAL

These series of transformers are used indoors. They are used for three phases of overdriven current protection in the electric not-useful-ground neutral system up to rated frequency 50Hz or 60Hz and rated voltage 35kV. The transformers are fitting with the relay too.

Being installed, at first, make the product dimidiation. Then make it coalition use bolt. Can be loaded in hot-line conditions.
