| 摘 要： | 目前正在运行的通信设备的直流电缆截面太大,安装和维护时施工困难,浪费投资,而且实际的负载电流偏小,压降很低.希望设计单位和设备厂家能够对通信设备的电压降重新进行整定和计算,将电缆截面降低到最小程度.在不影响设备正常运行的条件下,降低施工难度、节省投资.

| Abstract: | The DC cable section size of the existing communication equipments is too big, which results either in the difficulty of installation and maintenance or in the insufficient electric current and lower voltage- in-need. They hope that the design unit and equipment manufacturer will review and re-calculate the voltage-in-need of communication equipments to cut the cable section size to the minimum in order to decrease the construction difficulty and save the investment on condition that keep the equipment in gear. |
