Prefabricated Substation (European type)
Prefabricated Substation (European type) is applicable to the power distribution system of outdoor three-phase AC with rated voltage ≤40.5kV on the high-voltage side and 0.22/0.4/0.69kV on the low-voltage side, with rated transformer capacity of 2500kVA and below, and rated frequency of 50Hz/60Hz, and is used as the distribution system to distribute and receive electric energy. This product is suitable for urban residential areas, development zones, garden scenic areas, high-rise buildings, industrial and mining enterprises, but also in the oil and gas fields, large-scale construction sites, etc. as a temporary power distribution equipment.
Product Features
Integrated high-voltage room, transformer room and low-voltage room three parts, for the eye-type or Pin-type arrangement, can also be arranged according to user design requirements.
The top cover adopts double-layer structure, and an air cushion is formed in the middle to effectively prevent heat radiation.
High voltage programmed is flexible, (SF6/Solid/Dry air) RMU can be adopted.
Low voltage programmed can adopt Drawer Type Switch / Fixed Type Switch.
The power supply scheme is flexible, can be used terminal power supply, ring power supply or dual power supply, etc.
Can realize telemetry, remote control and real-time monitoring of the substation.
