Проходной трансформатор тока ТПОЛ-10 III наружной установкиDescription

Transformers are intended for transfering of measuring information signal to measuring instruments or to devices intended for protection, automation, signalling andcontrol in AC electrical appliances for the voltage class of 10 kV and frequency of 50 Hz.

Transformers are intended for mounting in units of commercial metering of electrical energy or in switchgears of outdoor mounting as a component parts. Climatic version "moderate cold" ("УХЛ") location category 1 as to GOST 15150.

Transformers are manufactured for internal market as well as for export.

It is possible to manufacture transformers with different transformation coefficients of secondary windings.
