Moisture Proof and Low Noise of Dry Type Transformers
SG(H)B 10 Series
6-13 KV & Rated Capacity: 125-2500 KVA
SG (H) 10 Series H Insulation Dry Type Transformer Definition is DUPONT "NOMEX" paper insulation system (NOMEX paper for level C insulation materials, high temperature 220 ℃).Air self-cooling type , Not casting structure,dry type transformer heat dissipation is good, never cracked, No fan operation, dry type transformer insulation class H (working temperature 180 ℃) Heat insulationthree phase dry type transformer.
Moisture Proof: H Insulation dry type transformer specifications, anti-short circuit ability and overload capacity is strong, can be long-term overload running 30%, also can't more than time limit temperature 180 ℃,Dry type transformer temperature rise is very reasonable, thus ensuring the safe and reliable operation for a long time. NOMEX paper electric constant is relatively low, uniform electric field distribution. It is difficult to produce partial discharge. Coating type design, dust and moisture proof good insulation performance, high applied in fire prevention requirements, big load fluctuation and filth wet industrial and high-rise construction site.
Low Noise: H insulation dry type transformer, no fan operation, reducing the noise of the fan operation. Bound with low magnetic design, core adopts advanced rolling technology, cancel the iron chip punching process, greatly reduces the electromagnetic noise and mechanical vibration noise .dry type transformer life expectancy 15-20 years
Environmental Protection: H insulation dry type transformer, the main insulation material heat-resisting level is high, the is level C (working temperature 220 ℃) combustion, flame retardant, no explosion, not release harmful gases, protect the environment and other equipment, especially the harm to the body. Dry type transformer efficiency is very outstanding. In the transport, storage, the runtime will not damage to the environment. The coil can be recycled and reuse of resources.
Dry type transformer connections,High voltage coil adopts the design of garden cylindrical coil, uniform voltage distribution, has a strong ability of lightning protection. If SG (H)10 Series dry type transformer winding local damage, Can the local repair,dry type transformer maintenance cost is low.
