试验规定，一根60cm长的试样垂直固定在前壁开通的金属箱内，火焰长度175mm的丙烷燃烧器从距试样的上部固定端450mm的位置上火焰锥和电缆以45度角接触，如果试样燃烧损坏部分距离固定端下部不超过50mm，测试通过。
MHYVP：聚乙烯绝缘聚氯乙烯护套煤矿用信号电缆，用于电场干扰较大的场所作信号传输，可用于固定敷设信号控制电缆用于工业环境下各种电气安装，连接、电源、控制、信号等。一般电压等级分为300V，300/500V，500V，450/750V，1000V等。
以380伏电动机为例说明。为了使电动机不过电流，就要维持磁通密度不变。在50HZ电源条件下，维持磁通密度不变的电压是(5O/60)X380=317伏。就是说只要把电源电压降至317伏，60HZ，380ⅴ的电动机在50HZ，380ⅴ的电源上使用不会发热。同时注意以下两个问题。电动机转速将降低17%左右。由于电压为额定电压的83%，降压后使用的功率仅为原电动机功率的83%。以上所述，在使用一些老电动机和进口设备(如美国，日本，韩国等)的电动机时希望对电工同行们有所帮助。
WDZ-KYDYD22铜芯无卤低烟阻燃聚烃绝缘聚氯乙烯护套钢带凯装控制电缆。WDZ-KYDYDR22铜芯无卤低烟阻燃聚烃绝缘聚氯乙烯护套钢带凯装控制软电缆。WDZ-KYDYDP22铜芯无卤低烟阻燃聚烃绝缘聚氯乙烯护套铜线编织屏蔽、钢带凯装控制电缆。
With the same negative level transmission, when in the light, their impact on the two wires are the same, thus reducing difference at the receiving end can block this (minus operation performed can be understood as a difference of two way). It can be seen from the principle of double stranded lines that the purpose of double stranded lines is to transmit. Therefore, when we make the joint of the twisted pair, we must not separate the two different transmission lines, otherwise it will greatly affect the transmission of the network.

When the data is transmitted at a high speed, the transmission line effect appears. At this point, the characteristic impedance of the load must match the output, otherwise, the echo will reflect and cannot work normally. Even though in some cases, can be done by resistance in the end of the parallel matching impedance matching, but in the long run, when the resistance change and come back down for some reason, besides, the disadvantages of this also leads to increased power consumption.
伺服驱动器主要有三种控制方式；1.转矩控制：转矩控制方式是通过外部模拟量的输入或直接的地址的赋值来设定电机轴对外的输出转矩的大小，具体表现为10V对应5Nm的话，当外部模拟量设定为5V时电机轴输出为2.5Nm：如果电机轴负载低于2.5Nm时电机正转，外部负载等于2.5Nm时电机不转，大于2.5Nm时电机反转（通常在有重力负载情况下产生）。可以通过即时的改变模拟量的设定来改变设定的力矩大小，也可通过通讯方式改变对应的地址的数值来实现。
