This series of cable branch boxes is suitable for outdoor distribution networks with AC 50Hz, rated voltage 12kV, and cable in/out lines. They are widely used in industrial zones, residential communities, commercial centers, as well as distribution networks for mining areas, airports, railways, ports, and power stations. They are particularly suitable for urban power grid renovation projects.
Key Features:
◆ Allows for flexible combination of load-break switches or circuit breakers with cable plugs, enhancing operational, maintenance, and repair flexibility for power lines. Reduces line outage time and improves power supply reliability. Can partially replace ring main units (RMUs) and switching stations, reducing overall system costs.
◆ Fully insulated, fully sealed, and maintenance-free, ensuring reliable personal safety.
◆ Simplifies urban cable network systems, saving investment costs.
◆ Outdoor type, dustproof, moisture-resistant, flood-resistant, and corrosion-resistant. Offers strong environmental adaptability and flexible configuration, with in/out lines ranging from 2 to 8 ways to meet various wiring requirements.
◆ Compact size, sturdy structure, aesthetically pleasing appearance, and simple installation. Maintenance-free, equipped with a voltage presence indicator. Options include a short-circuit indicator and surge arrester.
◆ Small footprint, low height, attractive appearance that harmonizes with the surroundings. Offers flexible and diverse wiring schemes, with extremely convenient installation and operation.
◆ The 200A cable plug is load-break capable, also functioning as an isolating switch. A short-circuit fault indicator can be installed to quickly locate faults.
◆ Altitude: Not exceeding 1000 meters.
◆ Operating Ambient Temperature: -30°C to +40°C.
◆ Relative Humidity: ≤ 95%.
◆ The surrounding air should not be significantly polluted by combustible gases, but may be subject to smoke, dust, or corrosive gases. The pollution severity level must not exceed Class III as per GB/T 5582.
◆ No frequent severe vibration.
When placing an order, customers must provide the following information:
◆ Primary circuit diagram and single-line system diagram.
◆ Specifications and material of cable plugs.
◆ Name and quantity of required accessories.
