The production of copper single wire is a matter that every manufacturer pays great attention to, because the quality and efficiency of wire drawing directly affect the process of subsequent work of the manufacturer, and it plays a decisive role in the quality of the cable. The following briefly dis... read more
1. In the installation of single-core wires, why is it necessary to install a return line parallel to the cable after one end of the single-core cable sheath is grounded? In a power line with one end of the metal sheath of the cable grounded, in order to ensure that the voltage induced in the sheath... read more
1.What are the requirements for the positive sequence impedance measurement of cable lines? The positive sequence impedance refers to the resistance of the cable conductor under AC voltage and the phasor sum of three adjacent inductive reactances in the cable connected in series. The positive-sequen... read more
There are a variety of inspection methods for wire and cable products. According to different inspection methods and functions, they can be divided into the following types: 1. Divided by process stage: pre-inspection and intermediate inspection; 2. Divided by inspection location: fixed inspection, ... read more
The quality of cable has been plaguing everyone, but in the end it is because of the production process, cut corners, and shoddy reasons. Even if it is a national standard cable, there will be errors within the allowable range. Especially today's production process has been able to minimize the erro... read more
