One of the primary functions of a cable branch box is power distribution. By distributing electrical energy from the power source to various terminal devices, it ensures the rational allocation and supply of electricity.

Additionally, cable branch boxes enable power monitoring and control functions, as well as provide safety protection for the power system, preventing electrical faults and overloads.

Cable junction boxes also offer excellent adaptability and compatibility. They can connect with various types of electrical equipment and systems, enabling interconnectivity between different devices.

This adaptability and compatibility allows cable junction boxes to be widely applied in diverse electrical systems and engineering projects.
