This cabinet’s core competitive advantages lie in its high customization flexibility, excellent high-voltage insulation performance, and strong fault protection capability. First, it supports full-range customization, including cabinet dimensions, internal component layout, and rated voltage configuration (10kV-35kV), meeting the unique requirements of different high-voltage distribution scenarios. Second, it adopts double insulation protection: the internal components are coated with 2mm epoxy resin insulation layer, and the cabinet shell uses Class F insulation materials, withstanding voltage up to 40kV, ensuring no insulation breakdown risks in high-voltage environments. Third, it has a 50kA short-circuit breaking capacity, which can quickly isolate fault currents within 0.01 seconds, preventing the spread of faults and reducing power outage time by 80% compared to standard high-voltage cabinets. Additionally, the forced air cooling system with explosion-proof fans maintains internal temperature below 40℃ under full load, ensuring stable operation of high-voltage components. The intelligent temperature monitoring system sends automatic alarms when internal temperature exceeds the threshold, enabling proactive maintenance.
The cabinet’s standard dimension is 2200mm (height) * 1000mm (width) * 1200mm (depth), with customizable dimensions ranging from 1800mm to 2400mm in height, 800mm to 1200mm in width, and 800mm to 1500mm in depth. It is constructed with 2.5mm thick cold-rolled steel plate with epoxy resin insulation coating, providing excellent insulation performance and corrosion resistance. The rated voltage ranges from 10kV to 35kV, with insulation grade Class F, capable of withstanding 1-minute withstand voltage of 42kV (10kV grade) and 95kV (35kV grade). The short-circuit breaking capacity reaches 50kA, meeting the requirements of large industrial plants and substations. The cooling system adopts two 150mm explosion-proof forced air fans, with air volume of 800m³/h, maintaining internal temperature below 40℃ under full load. It complies with IEC 62271 and GB 11022 international high-voltage standards, with type test certificates issued by authoritative institutions. The cabinet supports ground-mounted installation, with customizable cable entry ports and busbar configurations to meet diverse high-voltage wiring needs.
This customized high-voltage power cabinet is widely used in various high-voltage power distribution scenarios. In urban substations, it supports high-voltage power distribution for residential and commercial areas, with customizable internal layout to accommodate different types of high-voltage circuit breakers and voltage transformers. In large steel plants, it provides high-voltage power supply for steelmaking furnaces, rolling mill control systems, and ventilation equipment, ensuring stable operation with strong short-circuit protection capability. In wind power grid-connected systems, it supports high-voltage power distribution for wind turbine converters and grid-connected transformers, with IP54 protection to withstand outdoor wind and sand environments. In large chemical plants, it provides high-voltage power supply for reaction kettle control systems and compressed air stations, with double insulation protection to prevent electrical sparks from triggering explosions. Additionally, it can be used in high-speed railway substations to support power supply for railway traction systems and signal control systems, ensuring reliable operation with high customization flexibility.
