Pad mounted transformer

Detailed description

  • Description
  • Technical data
YB() American-pattern tank-type transformer, also called pad-mounted transformer, is a functional and energy saving combined transformer which integrates the high voltage device, low voltage device, transformer and other components. Its small but strong body and high efficiency make it suitable for outdoors and indoors usage. Strong tank protection
The sealed tank is made from high quality stainless steel with special design which helps to protect the devices and reduce the heat inside. Excellent cooling and drying system
Temperature control system and humidity control system are installed. When the temperature or humidity reaches certain levels, the systems automatically work to maintain the safe condition inside the tank. Functional and reliable
It owns loop or dual power supply and terminal power supply two ways of power supply. Therefore, it can serve as a substation. Lower cost and higher efficiency
It costs less than the traditional distribution house and only covers the area of about 3cbm.
Safe
All the devices are isolated by thick steel board. The efficient insulation system helps to protect the people from electric accident. Easy installation and maintenance
The installation only requires connecting the cables. The fully sealed transformer design keeps the oil away from the air, so it is free of maintenance.Working conditions:
