10kV Oil-immersed enclosed distribution transformer

SH Power offers full life-cycle support for its transformers,covering solution design, model optimization, and on-site commissioning—all handled by our experienced technical team. We provide tailor-made solutions for various applications to ensure efficient operation and maximize energy savings.

Description

The product is subject to GB/T1094 Power transformers, GB/T6451 Technical parameters and requirements for oil-immersed power transformers and GB20052 Minimum allowable values of energy efficiency and the energy efficiency grades for power transformers. For the core of the three-phase oil-immersed power transformer, 27QG120, 27QG100, 23RK085, 18R060 or other cold-rolled silicon steel sheets are used. In actual production, the core used may not be lower than the drawing requirement.
The product is of a fully-enclosed corrugated steel tank structure, with the transformer oil isolated from surrounding air, so that the transformer oil will not absorb water from air to reduce the dielectric strength. That aside, by preventing entry of oxygen into the tank, aging of the insulating material can be avoided, thereby prolonging the service life and promoting the social benefits of the product.

Product functions

Long service life: The transformer tank is of a fully closed structure, with the tank and tank edge connected by bolts or welded to prevent exposure of the transformer oil to air, thereby prolonging the service life.
High operating reliability: Parts and components related to the tank seal are improved to enhance their reliability, and technology is improved to ensure reliability of the seal.
Occupancy of a small land area: Transformer tanks of the S-M series are provided with corrugated plate radiators. When the oil temperature changes, the corrugated plates expand or contract to play the same function as a conservator tank. The corrugated plate tank looks good and occupies a small land area.
