Overview

This series of cable distribution boxes is designed for AC 50 Hz outdoor distribution networks with a rated voltage of 12 kV and cable in/out lines. They are widely used in industrial parks, residential communities, commercial centers, mining areas, airports, railways, ports, power stations, and other distribution networks, making them especially suitable for urban power grid renovation projects.

Key features include:

1. Fully insulated, fully sealed, and maintenance-free design, ensuring reliable personnel safety.

2. Simplifies urban cable network systems, reducing investment costs.

3. Outdoor type, with excellent dust-proof, moisture-proof, flood-resistant, and corrosion-resistant performance, boasting strong environmental adaptability. Flexible combination options, with 2 to 8 in/out lines to meet various connection requirements.

4. Compact structure, aesthetic appearance, simple installation, and maintenance-free operation. Equipped with live-line indicators, short-circuit indicators, and optional surge arresters.

5. Small footprint, low height, and aesthetic design that blends harmoniously with the surrounding environment. Flexible connection schemes allow for easy installation and operation.

6. 200A cable connectors support live-line plugging, while also functioning as disconnectors. They can be equipped with short-circuit fault indicators to quickly locate faults.

7. Can be freely combined with load break switches or circuit breakers and cable connectors, improving flexibility during line operation, maintenance, and repairs. Reduces outage time, enhancing power supply reliability. Can replace some ring main units or switchgears, lowering overall system costs.
