oil immersed distribution transformer,
oil immersed power transformer
oil-immersed transformer S11,30-2500KVA,6.6KV series,3 phase/fully sealed/double winding
6.6 KV - S11 type three-phase oil-immersed transformer insulation structure of advanced and reasonable, anti-short circuit ability strong, the performance reached the international advanced level of similar products, compared with the integrated type products, no-load loss dropped 10.25% on average, a 37.7% drop in no-load current, average load loss by 22.4%, and beautiful shape, reasonable structure according to user requirements can be tank type and tube type radiator.
of high voltage
1, all the use of high quality grain orientation cold rolled silicon steel sheet iron core, all inclined non-porous binding structure, iron core is multi-step ladder, three or five joints, low air loss, low noise;The coiling iron core is directly wound by special equipment, without joint and Angle weight, which reduces the magnetoresistance and reduces the air loss.Compared with traditional silicon steel sheet, amorphous alloy transformer core can reduce the air loss by 72% and the no-load current by 50%.
2, coil: the use of high quality retractable enameled round copper wire, no oxygen copper rod drawn flat copper coin or copper knot winding, its form is cylindrical, continuous, new spiral, split, etc., with sufficient electrical strength, mechanical strength and heat dissipation capacity.
3, tank: adopt high quality steel plate welding and become, such as elliptic shape, structure, heat dissipation component adopts chip radiator, expand the radiator or corrugated tank, fuel tank and reliable sealing experiment was carried out in the factory, both inside and outside surface after pickling, phosphating treatment, for three times primer, a paint spraying again, product has, hot and humid, salt mist prevent mould, beautiful and durable.
Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won’t split or move even under the influence of short circuit.
Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.
High-quality rubber sealing material, which can prevent the transformers form aging or leakage.
