Product introduction:

The upgrading project is to replace the station equipment with totally enclosed disconnect switch, totally enclosed drop-out fuse cutout, totally enclosed arrester and pre-insulated clamps, on the basis of existing overhead station. This is the simplest and most reliable way to speed upgrade the station for good equipment insulation, shortening power outage time.

The 10kV all enclosed overhead station upgrading project follows the concept of overall design standardization, independent functional module, and flexible equipment exchange. It comprehensively considers the reliability, construction cost, operation and maintenance habits of the overhead station equipment set, as well as the standardization and interchangeability of various components, to meet the development trend of constructing international higher distribution network lines. It is of great significance to improve the quality of the distribution network and improve work efficiency.
