Distribution transformers OLSP (ОЛСП) with built-in protctive deviceDistribution transformers OLSP (ОЛСП) with built-in protctive device
Description
The transformers are intended for embedding in factory-assembled switchgears, conductions and are used for powering measuring, protection, signal and control circuits in electrical devices of alternating current with frequency 50 or 60 Hz. Transformers are manufactured in compliance with the standard requirements of GOST 15150 in climatic versions "Y" (temperate) and "T" (tropical) location category 2.
Mounting in any position.
The transformer is patented 1. Patent certificate № 2208860. 2. Certificate № 53160 on industrial unit.
