???? In flame retardant series products, has been successfully used in the oxygen isolation technology, not only 0.6/1 kv polyvinyl chloride insulated and crosslinked polyethylene insulation flame retardant power cable can achieve GB/T12666.5 "into A bunch of power cable test" in class A, and rated voltage up to and including 6/10 kv 8.7/15 kv crosslinked poly (flame retardant power cable can reach A high class A demand and A large margin. On the basis of high flame retardant and high flame retardant cross-linked insulation, a low-smoke halogen-free high-flame retardant oxygen insulation layer power cable was added, and its low-smoke halogen-free performance was in line with GB/T17651.1.2 and GB/ t1765650.1.2. In this way, the overall level of the company's cross-linked power cable is lower than the domestic status. This company produces the type refractory power cables for rated voltage 0.6/1 kv copper core cable, can also produce low smoke zero halogen fire-resistant power cable, high flame retardant fire-resistant power cable oxygen insulation layer, the fire-resistant performance in line with the GB/T12666.6 cable fire resistance test. Therefore, the overall performance of refractory series power cables is good and reliable. The water resistance performance of fireproof cable conforms to iec 502-2.



Coaxial cable with hard copper wire as the core, outsourcing a layer of insulation materials. The insulating material is surrounded by tightly woven network conductors and covered with a protective material. There are two widely used coaxial cables. One is the 50 ohm cable, which is used for digital transmission. The other is the 75 ohm cable, used for analog transmission, or broadband coaxial cable. This distinction is made for historical reasons, not for technical reasons or manufacturers.

对于控制变频器，启停使用硬接线图三典型变频器的MODBUS控制如图三所示，只是一个变频器的控制电路，图中红色圆圈部分，是用硬接线控制启停，黄色荧光笔部分，使用MODBUS通信写入频率，读取实际频率和电流。如果完全使用MODBUS通信，启停部分就使用一个通信字，而且一旦通信死掉，变频器就处于失控状态，这是很危险的。而使用硬接线控制启停，无论任何情况下，都能确保变频器可以安全可靠的停下4.波特率波特率越高，通信速率越快，但是稳定性降低，很容易受到干扰。

同时配电箱内的零线排就成了“火线排”，始终带有电压。极易造成漏电甚至引发火灾。如何判断入户线是否接反呢？很简单，测量两个地方——可以用测电笔测量零排，主开关合闸、支路开关全部断开后，如果零排可以点亮电笔，则说明入户线的零火线接反了——前提是配电箱内接线没错。也可以将主开关闭合、支路开关断开后，测量1P漏电开关或1P+N开关的“N”接线柱，如果电笔可以点亮，则证明入户线的零火线接反了。这种情况解决起来很简单：先去电表箱（一般在楼道里）把自己家的断路器断开，把配电箱主开关的进线拆掉，调换顺序即可。
