Introduction
- European style pad mounted transformers are distinguished by their very low overground height and minimal built-up area. They are exceptionally easy to transport and simple to install. The maintenance is also quite simple, no special duty needed to attend the station. They can be installed right in the load centre, thus improving the supply quality, reducing energy loss and enhancing the reliability of power supply.
- Sub-station series(European Style box)
|
Features
- The substation consists of high voltage switchgears, low voltage power distribution panel, power distribution transformers and the housing. Air type load switch is used for high-voltage line, transformer is either dry or oil type. The housing is also designed and built with good ventilation structure, improved insulation, along with upper and lower ventilation air duct, the temperature rises caused by outdoor solar radiation on transformer chamber and both high and low voltage chamber can be reduced to minimum. Upon request, the housing can be equipped with forced ventilation devices and automatic temperature control device. Each independent unit is installed with complete control, protection, data display and lighting systems.
