The performance of the 35 KV series three-phase oil immersed power transformers produced by our company complies with the national standards GB1094-1996 "Power Transformers" and GB/T6451-1999 "Technical Parameters and Requirements for Three Phase Oil Immersed Power Transformers". The iron core is made of high-quality cold-rolled silicon steel sheets, with stepped three-level seams and surface coated with curing paint, reducing losses and noise; The coil is wound with high-quality oxygen free copper wire, and the heat dissipation adopts a new oil channel structure. The design is reasonable, and the insulation process is optimized to improve mechanical strength and short circuit resistance. The appearance is beautiful, generous, and reliable, and it is widely used in substations and urban and rural power grids.
