Product Description
75kv to 2500kVA Compact Transformer Substation Pad Mounted Transformer
Product features
1.The shell is designed according to foreign technology, and has the characteristics of firmness, heat insulation, ventilation, corrosion prevention, dust prevention, water prevention, small animal prevention, beautiful appearance, etc. There are many choices of shell materials, such as aluminum alloy plate, steel plate, composite plate, stainless steel plate, non-metallic materials (glass fiber cement), etc.
2.High voltage switch gear choose xgn15, hxgn17 or kyn28a high voltage switchgear as incoming line, high voltage metering and high voltage outgoing line. The high-voltage side can be arranged into a variety of power supply modes, such as loop network power supply, terminal power supply, dual power supply, etc., and high-voltage metering elements can also be installed to meet the requirements of high-voltage metering. Load switch or vacuum circuit breaker is generally selected as the main switch, with compact and reasonable structure and perfect anti misoperation function
3.Low voltage switchgear choose GGD, GCS or MNS etc. as low-voltage incoming line, reactive power compensation and low-voltage outgoing line. The low-voltage side adopts panel type or cabinet mounted structure ,which can meet the power distribution, lighting distribution, reactive power compensation, electric energy measurement and other functions. The main switch generally adopts ordinary load switch or intelligent circuit breaker, with flexible installation and simple operation.
