Pad-mounted transformers, also known as American substations, are an integrated power station that combines high-voltage control, protection, transformers and power distribution equipment according to specific wiring requirements. Transformer bodies, high load breaking switches and fuses are all set in fully sealed transformer oil tanks, and the transformer oil features an outstanding insulation performance and heat dissipation performance. Pad-mounted transformers feature a small size and light weight, as well as a safe, convenient installation and maintenance. They are widely used for outdoor power supply in cities, residential areas, hospitals, factories, mines, airports and railways.

• Altitude: ≤1000m
• Wind speed: ≤35m/S (≤700pa)
• Ambient temperature: -35ºC - +40ºC
• Relative humidity: daily average humidity≤95%, monthly average humidity≤95%
• Quakeproof: horizontal acceleration≤0.4m/s2
• vertical acceleration≤0.15mm/s2
• Installation site slop: ≤3º
• Installation site: the place without fire and explosion danger, serious pollution, chemical corrosion and strenuous vibration

• Small size and compact structure. The area covered is only 1/3 to 1/5 that of European substations of the same capacity.
• Low noise and strong overload capacity S11 series transformers: The system includes high-voltage chambers, low voltage chambers, and transformers. The high voltage components feature fuse protection and are used for loop networks and terminals. Power supply methods are also flexible.
• High-voltage chambers are equipped with oil humidity gauges, oil level gauges, pressure relief valves and oil discharging valves to monitor transformer operation states.
• High voltage inlets use cable plugs and can be equipped with zinc oxide arresters. We will meet your needs for a variety of low voltage outputs and low voltage measurements, with shunt outlets added according to customer requirements.
• The transformers utilize corrugated plates for heat dissipation. These plates are treated using a special technology for an exceptional corrosion resistance and a variety of shapes and structures. Common plates and stainless-steel plates can be chosen according to your needs.
