Network decoupling transformers OL-0,3/35 (ОЛ-0,3/35)

Network decoupling transformers OL-0,3/35 (ОЛ-0,3/35)

Network decoupling transformers OLDescription

The transformer is intended for galvanic uncoupling of powering and consumption circuits.
The transformer is manufactured in compliance with standard requirements GOST 15150 in climatic version "УХЛ" (temperate) location category 1 and is intended for usage at the following operating conditions:

  • altitude above sea level is not higher than 1000 m;
  • environment should be non-explosive, without corrosive steams in concentrations that are likely to destroy metal or insulation (atmosphere type II as to GOST 15150);
  • mounting vertical position.

The transformer is patented
Patent publication №2190276;
Patent Certificates on industrial unit №50676
