How to contral faulty wires
Neutral point is not directly grounded system, single-phase fault grounding can continue to operate, but with a sound phase voltage rise, if the Lmin internal energy to remove the grounding fault, the voltage rise of the impact on the insulation is generally negligible. However, according to the existing automatic d...
Wire and cable in the power system, especially in the transmission line is essential, there are several kinds of classification, there are special cables, insulated cables and so on, the following will be the most comprehensive introductio
Cable after-sales service
To ensure the quality of cable troubleshooting, as a cable after-sales staff need to make the following three aspects of the preparatory work.1. and actively with the user to conduct a comprehensive and effective communication, fully understand the actual situation of the scene failure.Ready to prepare all kinds of testing...
Aluminum alloy cable is based on ordinary aluminum to add trace elements as a conductor cable form, although the aluminum cable upgrade version, but compared with the copper cable is still a significant disadvantage.1. aluminum alloy cable conductivity is poor
Aluminum alloy cable conductivity is only 61% of copper cable. The same cable section, th...
The difference between twisted pair and aluminum phase conductorsCable and wire have many differences in size, structure, use, and characteristics, so they can not be confused with each other. To distinguish between these is actually very simple, below to give you a detailed description.
1 Material distinction wire is used to carry current c...
According to the analysis of the cause of the outer sheath, it can be seen that the cable line project is a systematic project, only from the design, construction, operation and maintenance aspects of its entire process management, in order to maximize its safe operation
BV Wire and Cable Color Separation MeaningBV line and cable color separation of the meaning of wire and cable wire, a variety of colors, various types, cable baby, you can sort out according to the color?
1 Black: the internal wiring of the device and equipment.
2 Brown: the positive pole of the DC circuit.
3 Red: three-phase circuit and C phase; semic...
Underwater Robot Cable Use EnvironmentThe underwater environment is bad, the depth of the diving is limited, underwater robots with an underwater mechanical arm, hydraulic cutter, and other operating tools, have become an important tool for the development of the ocean, and in such an environment, the ordinary cable is no longer suitable for work, Sh...
The way to choose housing wire and cableElectric wire is a more important part of our home improvement, but most people do not pay is wrong, the wire can be related to the home after the electricity problem. Because the wires are buried in the wall inside, if the choice of improper, the problem will be very troublesome maintenance.Meet the Relevant National St...
Selection of low-voltage power cable In the AC system, the rated voltage between phases of the conductor of the power cable shall not be lower than the voltage of the working line of the usual circuit. The low-voltage power cable should be insulated with cross linked polyethylene or polyvinyl chloride. In general, YJV-0.6/1KV - is selected &n...
