SGZB(H)10 6-10kV Environmental Protection Dry-type On-load Transformer
Scope of application
SGZB(H)10 type H class insulated dry type power transformer has strong impact resistance, large over-load capacity, flame resistance, high fire performance, low loss, small local discharge, low noise, no harmful gas, no pollution to the environment, insensitive to humidity/dust, small size, no cracking, easy maintenance, therefore, It is most suitable for the harsh environment with high fire protection requirements, large load fluctuations, and dirty and wet, such as: airports, power plants, metallurgical operations, hospitals, high-rise buildings, shopping centers, densely populated areas, and petrochemical, nuclear power plants, nuclear submarines and other special environments.
Structural characteristics
Iron core
The core is made of Japanese high quality 30ZH120 high permeability silicon steel sheet with low no-load loss. The surface of the core is coated with H-class insulating resin to prevent moisture and rust. The insulation system of the coil adopts NOMEX insulation material of American Social Company, impregnated solventless insulating paint by VPI vacuum pressure dipping equipment for many times, and heated at high temperature curing, high mechanical strength, high electrical strength.
Strong ability to withstand thermal shock: insulation material flame retardant, self-extinguishing, fire performance high and low loss, low noise, low discharge; Insensitive to temperature and dust Small size, light weight, easy maintenance, long service life using vacuum on-load voltage regulator, high voltage adjustment sensitivity, stable output, safe, reliable, energy saving, easy to recycle after life, no pollution
