    由低处往高处输送电缆的方法是将电缆输送机放在低处的某一适当位置，先把电缆盘上的外层端头拉到下终端位置，就位后制作好下终端，这是一种轻而易举的事情。然后把盘上的剩余电缆全部拉出来，牵引电缆的另一端，沿电缆线路路径向高一端敷设。这种方法不便于采用排油敷设，因为在牵引向上的电缆端部很难接上真空泵或充气设备进行敷设。由于电缆的重量大，向上牵引要比采用制动闸从高处向低处遛放困难些。同时，这种方法往往受场地的限制，电缆不能太长，敷设落差不能太高。因此，这种敷设方法可以采用，但有局限性。

From low to high transmission cable method is put cable in a lower position, to pull the outer end of the cable tray to the terminal position, is made under the terminal after in place, this is a kind of easy.Then all the remaining cable in tray, the other end of the traction cable, the cable laying lulu radial high end.This method is not easy to use oil discharge, because in the drawing up of cable end access to vacuum pump or aeration equipment installation.Due to the weight of the cable, upward traction than the brake diffuses from walking difficult.At the same time, this method is often limited by space, cable can't be too long, laying head cannot be too high.Therefore, the laying method can be used, but there are limitations.
