Shore Power Supply
Product Overview:
The LA series high-power shore power supply is a specially designed and manufactured 60Hz variable frequency power supply equipment developed by our company according to customer needs, specifically for harsh industrial environments such as high temperature, high humidity, high corrosiveness, and heavy load impact. Our existing mature products can reach up to 3000KVA in single unit power. It complies with China Classification Society (CCS) marine product certification standards and is widely used in applications such as on-board ships, shipbuilding and repair, offshore drilling platforms, and shore terminals for powering marine electrical equipment. With its strong research and manufacturing capabilities, Longrui has become a supplier to many large well-known shipyards and port machinery manufacturers in China.
