Core: The domestic advanced automated production line equipment is used to produce the core, which greatly improves the production accuracy and efficiency.

The use of laser-scored high-permeability silicon steel sheets not only reduces production costs, but also ensures product quality. The non-punching core design is combined with the international step-by-step lap-binding structure to make the electric field distribution of the core joint more uniform, and the no-load loss can be reduced by 4-6% compared with similar products on the market.

Coil: TSTY produces a variety of structures such as cylindrical, foil, spiral, and continuous to meet the diverse needs of customers. The coil is equipped with an oil guide structure to significantly reduce the temperature rise and eliminate the risk of transformer short circuit. The end angle ring effectively improves the coil characteristics under impulse voltage to make the voltage distribution more uniform.

Oil tank (35KV): The oil tank adopts a barrel or bell-shaped structure, which makes the structure more stable; the heat dissipation element adopts a sheet radiator, which has a better heat dissipation effect. The box wall is formed in one step by a large bending machine to enhance the mechanical strength of the oil tank and effectively improve the appearance quality. The flat-top box cover is easy for daily maintenance of the equipment. The edge of the tank is sealed with oil-resistant rubber material, and a sealing strip slot is provided to prevent leakage. Fluorescent leak test and pressure test are strictly checked to ensure no leakage.

Oil tank (11KV): The oil tank frame adopts angle steel reinforcement structure, and the mechanical strength is enhanced. The corrugated heat sink adopts one-time molding and automatic welding process, and the product is more beautiful. The outer surface of the oil tank is treated with phosphating, degreasing and rust removal, and then electrostatic powder spraying process is carried out, and the product is durable. Water pressure, air pressure and oil pressure are used for three leak tests during the production process to ensure that the oil tank does not leak.

TSTY is a professional transformer manufacturer! We have three production bases: dry-type transformer production base, oil-immersed transformer production base and high and low voltage complete production base, with a total area of 250,000 square meters. We have more than 500 employees, more than 100 senior engineers and electrical R&D personnel. We have advanced transformer production and testing equipment to ensure that we provide customers with high-quality power transformer products.

TSTY is the first digital transformer factory in Henan Province.
