Low voltage cable

对于新安装的电缆，应该进行电缆长度测试。和所有的导线一样，由于低阻 电缆的电阻会降低通过它的功率，因此就需要知道低压电缆的实际长度。 电缆长度越大，由于电缆引起的功率减小（衰减）就越大。由于信号是以低功率的形式传送的，电缆引起的任何功率下降都必须降至*小。

For newly installed cables, cable length should be tested. As with all conductors, because the resistance of the low resistance cable will decrease its power, it is necessary to know the actual length of the low voltage cable. The larger the cable length, the greater the power attenuation (attenuation) due to the cable. Since the signal is transmitted in a low power form, any decrease in power caused by the cable must be minimized.低压电缆

电缆长度测试测量的是电缆的长度， 通过测量包含两根或多根导线的电缆末端，还可指示出到电缆故障的距离。

The length of the cable is measured by the length of the cable. By measuring the end of the cable containing two or more wires, it can also indicate the distance to the cable fault.

电气开关装置和配电盘排障

Electrical switchgear and distribution disc barrier

电气开关装置和配电盘是金属封闭的 独立成套设备，它包含断路器和/或有 保险丝的断开开关。它还包括母线、电缆端接点、备份保护装置和不同形式的控制装置和仪表设备。(http://www.dgzj.com/ 电工之家)开关装置或配电盘用来通过连接到变压器、配电箱和马达起动器的配电通道分配市电。

Electrical switchgear and switchboards are metal enclosed independent sets of equipment, which include circuit breakers and / or disconnecting switches with fuses. It also includes busbars, cable end contacts, backup protection devices, and different forms of control devices and instrumentation. (http://www.dgzj.com/ electrical home) switchgear or switchboards are used to distribute electricity through distribution channels connected to transformers, distribution boxes and motor starters.
