The products are the transformers which installed on-load switch and full range protected fuses of high voltage current-limit in the tanks, using transformer oil as an insulating and cooling medium. The entirely sealed structure has the excellence, such as: small size, light weight, convenient installation, etc..

The transformers can withstand shake and bumps in long-distance transportation way, and routine core inspection are not needed when the transformers sent to installation place.

Boxes are adopted the special process, and they have good anti-corrosion ability to effectively prevent wind erosion and coastal salt spray.

The cabinets of high-voltage and low-voltage are set with anti-wind and anti-rain crust, and both are used the "L"-type arrangement. The door of high-voltage cabinet is adopted web electromagnetic lock protection. It could be set surge arresters and displays and other electrical components by the users' requirements. Low-voltage cabinet could be installed the protection, measurement and display devices such as framed-breaker or fuse according to the different requirements of users.

ZBW (YB) Series modular substation is combined with high-voltage room, transformer room, low-voltage chamber. It has excellencies such as run a safe, reliable, complete and strong, lower total cost, short installation, operation and maintenance simple, handsome in appearance and so on.

This product can be used for loop power supply distribution system, also can be used as the terminal radial grid electricity.
