Product Introduction

The low-voltage cable branch box is a device used for cable line tapping, branching, splicing, and circuit switching. Primarily used outdoors for "secondary" power distribution, it connects power cables to equipment such as box-type substations and load-break switchgear, facilitating the networking of cable systems.

Product Classification

①　By electrical configuration: Standard branch boxes contain no switching equipment; incoming and outgoing lines are connected via copper busbars, making them suitable for simple tapping or branching (often used in rural grid projects). Advanced branch boxes contain switching equipment, enabling functions such as tapping, branching, control, and switching.

②　By installation method: Available in floor-standing and wall-mounted types. Floor-standing units offer high stability and are suitable for installation on the ground in various environments. Wall-mounted units save space and are ideal for locations with limited room.

③　By installation environment: Classified into indoor and outdoor types. Indoor units are designed for interior environments with relatively lower protection requirements, whereas outdoor units are built to withstand harsh weather conditions, including wind, sun exposure, and rain.

Key Features

①　Branching and Interconnection: Distributes electrical energy from a main cable to multiple branch cables, supplying power to various users or equipment; also facilitates cable line extensions and interconnections.

②　Protection Functions: Equipped with multiple protection mechanisms—including overload, short-circuit, and earth-leakage protection—and an integrated surge protection device to prevent equipment damage from lightning strikes and overvoltage.

③　Intelligent Monitoring: Smart low-voltage branch boxes monitor electrical parameters (such as current, voltage, and power) in real-time and support remote monitoring and management, enabling functions like fault early warning and status diagnostics.

Application Scenarios

①　Commercial Buildings: Suitable for hotels, shopping malls, and similar facilities; enables real-time power load monitoring, intelligent power distribution, and fault early warning, thereby enhancing electrical safety and reducing O&M costs.

②　Industrial Production: Facilitates precise power supply control for production line equipment in factory workshops, ensuring stable line operation and optimizing energy usage.

③　Public Facilities: Provides reliable power supply for schools, hospitals, airports, and other venues; enables timely handling of electrical faults via remote monitoring to ensure public safety.
