ZBWS Solar Energy Photovoltaic IntelligentPrefabricated Cubicle-Type Substation is a product developed in combination with the state-of-the-art technology and the power supply demandfrom domestic and abroad market. Booster transformer is made with the “split”coil structure, which has largely improved the system efficiency. ZBWS consistsof US and European structural types. The US structure is characterized thathigh-voltage load switch, fuse, booster transformer and excitation-free tap switchare installed in the oil tank of the transformer, and the transformer oil isused as the insulating medium, generally with the “Δ” structure; the Europeanstructure is characterized by the integration of booster transformer,high-voltage load switch, low-voltage switch, intelligent monitoring andauxiliary devices in the public cabinet.
