The utility model relates to a communication system is hauled oneself willingly into fully to junctor of standing between territory based on carrier technique, be equipped with communication module on haul oneself willingly into device, carrier wave device, communication interface, communication module fully, hauling oneself willingly into the device fully, communication module passes through communication interface and is connected with the carrier wave device, and every carrier wave device links to each other with corresponding 220kV transformer substation, through the arbitrary looks communication in the existing power line between two carrier wave devices. The advantage is: adopt carrier technique, the high frequency signal load that will be loaded with information carries out data transmission with the power line to the power line, practices thrift a large amount of social cost and operation cost, and economic benefits is showing, when a transformer substation decompression full cut -off, by the power supply of adjacent transformer substation, realizes that two transformer substations are reserve mutually.
