S11 Series Oil-immersed Power Distribution Transformer
1. Principle & Characteristics
S11 Series three phase oil immersed transformer with load series comply with national standard GB1094 Electrical Power Transformer and GB/T6451 Technical Parameters and Requirements for Three Phase Oil Immersion Type Power Transformer. Voltage regulation range with load: 10±4×2.5%KV,35±3×2.5%KV, Voltage regulation range without excitation:10±2×2.5%KV,35±2×2.5%KV. By using with load switch and no excitation regulation switch, regulate voltage in the regulation range manually, electrically or automatically to ensure stability of output voltage. On the body of transformer, there are three positioning points at upper, middle and lower, and there are also loose proof and shock proof measures, so that there is no need to lift core and check before installation and it is shock proof. Oil tank is made of high quality steel plate, with high mechanical strength. Rubber stripe and rubber mad are made of latest high quality acrylate product which won’t age even after long period of operation and as a result effectively prevent oil leakage.
