What are the selection skills of industrial control cables

Industrial control cables are also used a lot in life and industrial power consumption, which makes everyone's life and work very convenient, and has also been highly valued by the State Grid. Industrial control cables also play an irreplaceable role in people's life and work. Function. When choosing an industrial control cable, you need to consider many aspects, so you must be careful when choosing, because industrial control cables affect the safety of all aspects, and if you choose improperly, there will be great hidden dangers. In the process of selection, there are A lot of matters needing attention, Min's cable will help you analyze it

.

1. When the control cable is working, the current, resistance and voltage must be within the specified range. When connecting to the secondary side of the current transformer, the cross-section measurement and checking should be carried out. If it is connected to a voltage transformer, it should be checked accordingly. Voltage drop. If an electric meter is used to measure the loop, it should be compatible with the measurement accuracy of the electric meter. If it is applied to an electric meter, it should also ensure that the voltage drop is less than or equal to 5% of the rated voltage.

2. When selecting industrial control cables, the use, laying conditions and safety should be considered; generally, according to different laying conditions, general plastic insulated cables, steel tape armored cables, steel wire armored cables, anti-corrosion cables, etc. can be selected; according to the safety If required, non-extended combustion cables, flame-retardant cables, halogen-free flame-retardant cables, fire-resistant cables, etc. can be selected.

3. Selection of industrial control cable specifications, when determining the use specifications (conductor cross-section) of industrial control cables, selection conditions such as heat generation, voltage loss, economic current density, and mechanical strength should generally be considered.

Generally, these factors will be considered when choosing. Of course, there are many other objective factors. Everyone should also consider the quality of the merchant's products, service, after-sales, etc., which must be related to everyone's potential safety hazards. The first important factor.
