Three-phase distribution transformer ТЛС (TLS) with cast resin insulationThree-phase distribution transformer TLS with cast resin insulation
Description
The transformers of TLS series (according to GOST 11677) are manufactured to satisfy needs of power industry, particullarly needs of power objects. Transformers are manufactured in 6 or 10 kV voltage classes according to standard requirmets of GOST 15150 in climatic version "YHL" (temperate outside mounting) location category 2 and are intended for usage under the following operating conditions:
- altitude above sea level is not higher then 1000 m;
- ambient air temperature considering overheating inside factorey-assembled switchgear from minus 50°С up to plus 50°С;
- relative humidity not higher than 100% at 25°С;
- 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 in vertical position.
The transformers are intended for usage in electrical appliances which are subject to lighting overvoltage at standard safety requirements, and have standard "b" level insulation as to GOST 1516.3, thermal stability class "B" as to GOST 8865 and inflammability class FH I as to GOST 28779.
