SC(B)9-30~2500/10 type cast resin dry-type power transformer
(kVA)Rated capacity 30, 50, 80, 100, 125, 160, 200, 250, 315, 400, 500, 630, 630, 800, 1000, 1250, 1600, 2000, 2500 Structural Features Iron core Made up of high quality cold rolled silicon steel sheet that is for electric engineering Low voltage winding Made up of a whole copper foil coils Low voltage terminal High voltage terminal Variable wiring mode, which is convenient for installation Resilient pad Avoid mechanical resonance, and reduce noise Clamp and trolley The wheel of trolley can rotates to 90 It is convenient for vertical and horizontal movement Packing type resin insulation With advantage of damp proof, anti-damp and hot, flame-retardant, and self-extinguish. Product characteristic Low local discharge As the coil is cast in vacuum state, the air bubble produced in coil can be prevented efficiently, the local discharging value fully accords with relative national standard. Strong capability of lightning impact The lighting impact voltage that affects the insulation of transformer windings along the initial voltage distribution of windings., the foil type windings initial voltage distribution approaches to linear one, therefore, the transformer manufactured by us has good ability to resist the lightning impact. Strong ability to resist short-circuit The width of copper foil of LV windings that is the reactance height, LV current is supplied according to the requirement for ampere turns balance among windings, HV/LV windings axial force caused by short circuit tends to zero. Good performance of anti-drying crack The transformer manufactured by us is made of packing type resin and designed into the structure of full copper oil, the coefficient of insulation material is the similar to the that of thermal expansion of copper conductor, so the coils can be perverted cracking efficiently.The transformer has been done kinds anti-crack tests, such as cold/hot alternation test, thermal impact test, rapid aging test, etc, and the test result demonstrates that our technology can meet the requirements of service occasions like low temperature, high temperature, and large range of variable temperature, as well as anti-crack after the transformer runs for a long time. |
