Compact substation is a highly integrated compact power distribution unit combining high voltage switchgear, distribution transformer and low voltage power distribution cabinet. Optimized compact layout greatly reduces occupied space, suitable for limited-site engineering projects. Adopts reliable insulation structure, multi-level electrical protection, ventilation and anti-corrosion design. Fast on-site installation and commissioning, effectively shortening project construction cycle. Widely applied in urban power grids, residential communities, commercial complexes, rooftop photovoltaic power stations and industrial parks. Customized capacity, voltage grade and internal configuration available for global power distribution projects.
