DC power-superposed multiplex transmission system with single parallel cable.

摘要

A power transmission system in which a power sending terminal is connected to a power receiving terminal via a communication cable made of a pair of parallel PVC-coated solid or stranded wires, the power sending terminal superposing DC-power on multiplex signals and transmitting the DC superposed multiplex signals through the communication cable to the power receiving terminal where DC power is separated from the multiplex signals to operate remote equipments.
