Zi Kai gis rmu ring main unit switchgear Precautions for use

Check the shape, size and integrity of the ring cage before installation. Replace the ring cage if damaged. When connecting, standard products must be used to ensure stability and safety. Verify connection seal and pressure resistance before use. Avoid damage to the box during transportation and use to prolong life. Regular maintenance of the ring cage, timely repair or replacement, to ensure continuous operation.

Zi Kai gis rmu ring main unit switchgear Feature

Highly integrated:

The primary and secondary fusion ring cage integrates the functions of the primary side and the secondary side into one device, realizing the seamless integration of multiple functions such as power distribution, protection, control, and measurement.

This design reduces the number of interfaces between devices and reduces the probability of failure.

Intelligent management:

Equipped with telemetry, remote communication, remote control functions, operation and maintenance personnel can remotely monitor the operating status of the equipment, timely detection and treatment of potential problems.

Rich functional configuration:

In addition to the basic power distribution function, the primary and secondary fusion ring cage also has rich functions such as metering, interphase and ground fault handling, communication, and secondary power supply.
