Product Description
Product Overview
The YGS-Z.G-1250 photovoltaic booster substation is designed to meet the growing power supply requirements of photovoltaic power generation, which has rapidly developed as a clean energy production method both domestically and internationally. Based on the production of 10kV and 35kV combined transformers, our company has developed a series of products by absorbing advanced technologies from home and abroad and combining them with domestic needs. This product integrates the transformer, load switch, and high-voltage fuse within the transformer housing, using the transformer’s insulating liquid as the insulation and heat dissipation medium for the entire product. It features a fully sealed structure, offering advantages such as small size, light weight, and easy installation.
