High voltage circuit breaking devices are connected between the cable and ground, usually in parallel with the equipment to be protected. The high-voltage circuit breaking device can effectively protect communication equipment, and once abnormal voltage occurs, the high-voltage circuit breaking device acts to play a role in protection. When the communication cable or equipment operates under normal operating voltage, the high-voltage circuit breaking device does not work and is regarded as a circuit break for the ground. In case of high voltage and endangering the insulation of the protected equipment, the high-voltage circuit breaking device acts immediately to guide high-voltage impact current to the ground, thereby limiting the voltage amplitude and protecting the communication cable and the equipment insulation.
