35KV Oil-Immersed Three-Phase On-Load Voltage Regulating Power Transformer

35KV Oil-Immersed Three-Phase On-Load Voltage Regulating Power Transformer

真人赌场体验 www.ruikanwuliu.com The coil heat dissipation of S11 series 35KV oil-immersed three-phase on-load voltage-regulating power transformer uses a new oil channel structure, with reasonable design, and optimization of insulation technology, improving mechanical strength and short-circuit resistance. The core is made of high quality cold rolled silicon steel sheet, staircase three-stage joints, and the surface is coated with curing paint, which reduces the loss and noise, beautiful in appearance and reliable in operation.
 

35KV Oil-Immersed Three-Phase On-Load Voltage Regulating Power Transformer

Technical specifications:
A. Normal operating conditions: no more than 1000M above sea level, the highest temperature + 40
, the hottest monthly average temperature + 30; the lowest temperature - 25 (for outdoor); and the lowest temperature - 5 (for indoor).

B. Maximum voltage is 40.5KV, rated lightning impulse withstand voltage: 200KV (full wave) 220KV (chopped wave), rated short-term external withstand voltage 85KV
C. The plateau type transformer can be selected when the altitude exceeds 1000M; for the transformer insulation oil, No. 25 transformer oil or No. 45 transformer oil can be selected in low temperature areas.
