Non-wound three-phase dry-type power transformers produced with the American UL-approved NOMEX insulation system offer reliable, energy-saving, fire-resistant, explosion-proof, and easy maintenance features. They boast advanced design, rational structure, attractive appearance, and key performance indicators that exceed domestic standards, including partial discharge level, no-load losses, load losses, noise levels, and adaptability to high humidity environments. Suitable for installation near lakes, seas, riverbanks, and in environments with high fire protection requirements and heavy loads, these transformers are ideal for high-rise buildings, airports, train stations, docks, subways, power plants, metallurgical industries, densely populated residential areas, as well as for oil and petrochemical plants, nuclear power stations, and nuclear submarines.

Product Features

1. The meticulously designed coil structure and vacuum impregnation process ensure that the SG(B)10 transformer does not experience localized discharge, and throughout its entire lifespan, there is no cracking or decrease in insulation level.

2. High voltage employs continuous winding, low voltage foil winding, with overall vacuum impregnation and curing treatment, and utilizes high-strength ceramic supports, offering excellent capability to withstand sudden short-circuit currents.

3. Flame retardant, fire-resistant, self-extinguishing, fireproof.

Under high-temperature open flame combustion, the SG(B)10 transformer produces almost no smoke.

Transformer is insulated to H-class (180℃).

6. The insulation is thin and even. It has strong short-term overload capacity and does not require forced cooling. It can operate at 120% long-term overload and 140% overload for 3 hours. Due to the non-aging and elastic nature of this insulation material, it can be immediately fully loaded under ±50℃ conditions.
