Cable performance design and reference for frequency converter: 1.83 kv and below are designed according to GB/Tl2706, 2002. Besides GBT/l2706.2002, the special cable for kv variable frequency motor has the re of capacitance and inductance. According to the actual use of the special cable for frequency conversion motor and the technical conditions of GB/T12706.2002 and ABB for power transmission cable, the electrical performance parameters of the cable were determined.

在并联电路中，支路电流的大小与支路电阻的大小成反比。改变Ip和IR两支路阻值的大小，即可改变电流分配比例，实现量程的转换。如下图所示。当被测电流I1从A端输入时，IP支路电阻为R0，IR支路电阻为R1＋R2＋R3。而当被测电流I3从A的3端输入时，Ip支路的电阻为R2＋R1＋R0，IR之路的电阻为R3。可见，当表头指示相同（IP相同）时，I3I1，扩大了量程。读数方法电流表指示的读书方法是：满刻度值（刻度线右边）等于所选量程档位数，根据表针指示位置折算出测量结果。

Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.


Solid insulated unfilled cable is a kind of internal communication cable designed for the urban communication network. Transmission of audio 1 50k H Z and below analog signals and 2048Kbit/S and below digital signals. Under certain conditions, it can also be used to transmit digital signals over 2048Kbit/S. In a 30 ℃ ~ + 60 ℃ environment conditions, the cable to ensure long-term, reliable running. Structure.
