Product Description

1. The carefully designed coil structure and vacuum impregnation process make the SG (B) 11 transformer free from partial discharge, and during the entire life cycle, there is no cracking phenomenon and no insulation level drop phenomenon.

2. The high-voltage adopts continuous winding and low-voltage foil winding, the whole is vacuum impregnated and cured, and is supported by high-strength ceramics, which has a good ability to withstand sudden short-circuit current.

3. Flame retardant, flame retardant, self-extinguishing and fireproof.

4. The SG(B)11 transformer hardly produces any smoke under the high temperature fire.

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

6. The insulating layer is thin and uniform. The short-term overload capacity is strong, no forced cooling is required, and the long-term overload of 120% and the overload of 140% can be performed for 3 hours. Since this insulating material does not age and is elastic, it can be fully loaded immediately at ±50°C.

Conditions of Use

1. Ambient temperature: -50°C~ +50"C

2. Altitude: ≤1000m

3. Other content beyond the provisions of this technical condition shall be dealt with through negotiation between the user and the technical department, and shall be indicated when ordering.

Model meaning

product description

The non-encapsulated coil three-phase dry-type power transformer produced by the US UL-approved NOMEX insulation system has the advantages of 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 environments. It can be installed near lakes, seas, and rivers. It is suitable for high-rise buildings, airports, stations, wharves, subways, power plants, metallurgical industries, shopping, densely populated areas, petrochemicals, nuclear power plants, nuclear submarines, etc.
