JP comprehensive distribution box
Product Introduction:
The JP Comprehensive Distribution Box, produced by our company, is a new type of integrated control box that combines electric power distribution, metering, protection, control, and reactive power compensation. It features functions such as short circuit, overload, over-voltage, and leakage protection. With its compact size, attractive appearance, economic and practical benefits, it is installed on outdoor poles at transformer locations. This product is an ideal distribution solution for urban and rural power grid transformations. Main application areas include substations, factories, industrial and mining enterprises, large power plants, oil and petrochemical companies, large steel mills, high-rise building power centers, reactive power compensation, metering, and power distribution scenarios.
Model Meaning:
Normal Operating Environment:
Ambient Temperature: -25℃ to +40℃
Relative Humidity: Daily average no greater than 90%, monthly average no greater than 90%
Altitude: Not exceeding 2000m
Installation should be in places without severe vibration and shock, and devoid of corrosive gases.
Performance Features:
The cabinet structure is available in both standing and horizontal types, with the outer shell made of 2mm high-quality stainless steel plate, bent through multiple folding processes (or using a honeycomb structure of stainless steel double sandwich composite board, which offers flame retardant, environmental protection, insulation, and anti-condensation properties). A special stainless steel welding process ensures high overall strength and a mirror-like smooth surface without weld marks after forming. Internal support beams (plates) are treated with hot-dip galvanizing to ensure no rust for twenty years. The cabinet has doors at the front and back for easy operation and maintenance, with high-elasticity, age-resistant sealing strips around the doors. Each door is equipped with two types of locks, open and concealed, with the open lock featuring a rainproof and rustproof cover. The metering compartment is fully enclosed with a lead-sealing device. The side of the cabinet is equipped with rainproof and foreign object-proof cable glands, while the bottom has ventilation holes and cable outlets. The top is designed with ventilation ducts and wire mesh, offering waterproof, rustproof, dustproof, and foreign object protection. Protection level: IP54.
