Introduction
Photovoltaic power generation as a clean method of energy production, has seen rapid development both at home and abroad. The YBF-12 photovoltaic in-situ booster substation is specifically designed to meet the growing power supply requirements of photovoltaic power generation. The 10kV and 35kV combined transformers produced by our company are designed with the transformer, load switch, and high-voltage fuse installed within the transformer case. The insulation liquid of the transformer serves as the insulating and cooling medium for the entire product. It has a fully sealed structure. The outer case is divided. It is shot-blasted, acid pickled, phosphorized, and then coated with primer, intermediate paint, and topcoat to realize superior corrosion resistance, durability, and UV protection over conventional spraying methods. The product is characterized by their small size, light weight, and ease of installation.
