Arc Protection Four Phase Three Phase Dry Type Transformer for Dock and Wharf

Product Description

• Box-type substations are compact power distribution equipment that combine various components into one or several boxes.
• American box-type substations have a more reasonable structure than European ones, with a cross-shaped layout and two-part structure.
• The front part contains high and low voltage operation intervals, while the rear part contains the transformer winding, iron core, high-voltage load switch, and fuse.
• American box-type substations have a smaller footprint and volume than European ones.
• They use fuses and plastic shell automatic air circuit breakers for high and low voltage protection, respectively.
• The load switch being immersed in oil can cause oil carbonization and decomposition, decreasing performance and causing accidents.
• There are no visible disconnect points, making maintenance inconvenient.
• American box-type substations do not come with low-voltage protection and metering, so domestically produced ones are equipped with low-voltage distribution cabinets.
• Exposure to direct sunlight can affect the heat dissipation of plastic shell circuit breakers, leading to potential high-voltage side faults.
