H Class Insulation Non-Encapsulated Dry Power Transformer is mainly used in high-rise housing, airport, station, dock, subway, hospital, power plant, metallurgical industry, shopping center, densely populated area and petrochemical industry, nuclear power plant, nuclear submarine and other places.

Product Features:

1. The well-designed coil structure and vacuum immersion treatment process make the SG(B)10 type transformer produce no partial discharge, and there is no cracking phenomenon during the whole life period, and no insulation level drops.

2. The high voltage adopts continuous winding, low-voltage foil winding, integral vacuum impregnation and solidification treatment and high-strength ceramic support, which has good ability to withstand short-circuit current.

3. Flame retardant, flame retardant, non-toxic, self-extinguishing, fire prevention.

4. Under the high temperature open flame combustion, the SG(B)10 transformer has almost no smoke generated.

5. The transformer is H class (180 ° C) insulation.

6. The insulation layer is extremely thin and uniform. Short-time overload capacity, no need for forced cooling, 120% long-term overload, 140% overload for 3 hours. Since this insulating material is not aged and elastic, it can be fully loaded at ±50 °C.


Product Description:

H-Class Insulation Non-Encapsulated Dry Power Transformer produced by the US-approved NOMEX insulation system has the advantages of safety, reliability, energy saving, fire prevention, explosion-proof, and simple maintenance. Its advanced design, reasonable structure, beautiful appearance, and main performance indicators are better than domestic standards, such as: partial discharge level, no-load loss, load loss, noise and adaptability to high humidity environment, etc., can be installed near the lake, the sea, Riverside polluted environment and high fire protection requirements, high load areas, suitable for high-rise buildings, airports, stations, terminals, subways, hospitals, power plants, metallurgical industries, shopping centers, residential areas and petrochemicals, nuclear power plants, nuclear submarines places, etc.
