Product advantages
> Leading technology
- Standard anti-corrosion and salt spray environmental plan to meet the stringent environmental requirements of the site
- Compact structure, small footprint, easy installation
- Fully enclosed, fully insulated structure, safe and reliable operation
- Easy to operate, maintenance-free, low equipment cost
> Enclosure
- Adopt cold rolled high quality hot dip galvanized sheet
- The surface is treated by electrostatic spray, and the paint can not be taken off for 50 years
- Laser numerical control equipment cutting, drilling, bending, to ensure the processing accuracy
- Product structure is divided into three parts: high voltage chamber, low voltage chamber and transformer
- The cabinet is mainly pre-installed with: lightning arrester, load switch, transformer tap switch, protection fuse, oil level thermometer, oil level gauge, pressure relief valve, amount of oil discharge valve and other accessories
- The low-voltage side is equipped with main circuit breaker, overvoltage protector, and can be designed and installed in complete sets of automatic measurement and intelligent control system
- The transformer is a low loss oil-immersed transformer produced by Hengfeng You Electric
> Functional units
- Fully sealed structure, using the transformer insulating oil as the insulating medium and heat dissipation medium, overall has the advantages of compact structure, good heat dissipation performance
- The high-voltage indoor door should be equipped with electromagnetic lock and live display. When the high-voltage side is live, the high-voltage chamber door cannot be opened. The external door of the box transformer should be equipped with mechanical lock to meet the five requirements of high-pressure products and ensure personal safety
> Components
