Ungrounded voltage transformer NOL-35 III for outside mounting

Description

Transformers are intended for mounting in opened switchgears. Transformers are intended for transmittion of signal of measuring instruments , protective instruments, as well as automation, alerting and control instruments in AC current networks with frequency 50 Hz.

Transformers are manufactured in climatic version "УХЛ" (moderate cold), location category 1 according to GOST 15150.

Mounting in vertical position.
