Brief introduction

We produce three phase oil immersed power transformers with rated power in range from 10 kVA up to 25,000 kVA. Our transformers are both types, hermetically sealed and with conservator. They are manufactured in accordance with local and international standards and fully adapted for mounting in complete transformer substations and steel-lattice poles. The windings can be made from aluminium or copper depending on customer requirements and needs. oil immersed transformer are most used in power plant, power grid transmission and distribution station, industry and commerce electrical substation as the electrical equipment of power transmission:

1. Two windings or three windings;

2. On-load or no-load voltage tapping changer;

3. Natural cooling or force air or oil cooling;

4. Capacity range 10-2500kVA.

Features

• Excellent short-circuit resistance
• Satisfies the various load conditions required by customers
• Low-loss step lap laminated core
• Uses latest insulation material with high short-circuit strength to realize high thermal capacity
• Cold steel sheet is used for radiating pipe to ensure a sufficient cooling effect and aesthetic exterior
• Compact, light, and low-noise transformer with standard efficiency and noise level which can be easily installed even in a small indoor or outdoor area
