Environmental protection dry-type power transformer :

Features of products:

SG(B) 10 type this series dry-type distributing transformer has strong withstanding of thermal shock,overload capacity. Beside, it has many good points such as flame-retardant,low-loss and low partial discharge capacity. Easy to be maintained. Therefore, it is suitable for the using in the adverse circumstances of high requirement for fire protection, high degree of load fluctuation and dirty, moist, such as airport, power plant, metallurgy, hospital, skyscraper, shopping center,and residential areas and other special environments like oil, chemical industry,nuclear power plant ,nuke, etc.

Core:

The iron core applies imported high-performance cold-rolled grain-oriented silicon-steel plate and it applies 45 fully-inclined joint form. Between the layers of winding, it applies flexible fastening device and makes no-load loss and noise low.

The iron core surface is dealt with special craft which makes the noise low and the iron core rustless during running.

The iron core is clamped bytensile rod and no punched hole. The upper and lower clamps are connected by drawplate and fixed with the base .by fixed with flexible pad and cushion structure ,it makes the winding of lower vibration and noise.

HV.LV Coil materials:

The high-voltage and low-voltage coils are made up of Nomex insulating material and dipped in solvent-free immersion paint many times by VPI vacuum pressure device and is solidified by high temp. baking. The high-voltage coil applies continuous mode structure which makes high voltage. Low heat dispersion , easy to be thermal runaway and low mechanical strength. It is therefore that the reliability of the product is ensured. The low-voltage coil applies foil or strong current helix structure of longitudinal air flue. After dipping. The coil has a good moisture proof , impacting resistance and no chapping, no partial discharge. It can be decomposed and recycled.
