Four main factors help you choose the right flexible control cable
High-flex cable is a kind of cable with better flexibility. It has been widely used in household and industrial electricity, which greatly facilitates people's life. At the same time, its development has also been highly valued by the national power supply network. Like highly flexible cables, flexible control cables play an irreplaceable role in people's lives. So what factors should be considered when choosing flexible control cables?
One is the laying conditions. Generally, shielded cables are used in places that resist electromagnetic interference, and flexible cables are mainly used in mobile devices.
Second, mechanical strength. Due to the small section of the control cable itself, it also has high reliability requirements during operation. According to relevant industry regulations, most cables are copper core cables. The diameter of the cable should be properly controlled during use. It applies to the diameter of the core when connecting two electronic terminals. The former requires generally greater than or equal to 1.5mm, and the latter requires greater than or equal to 0.5mm.
Third, load capacity. When the cable is running, the current, resistance and voltage in the circuit must be within the specified range. Also check the correlation of the cross section when it is connected to the secondary side of the current transformer. If it is connected to a voltage transformer, check its voltage drop accordingly. If a meter is used to measure the loop, it must be adapted to the measurement accuracy of the meter. If it is applied to a billing meter, the voltage drop should be less than or equal to 5% of the rated voltage. For automatic devices, relay protection and control circuits, the former two should not be greater than 3%, and the latter should be less than or equal to 10%.
Fourth, the number of cores. Generally, the more the number of cable cores selected, the less the number of cables can be used. Also, generally cables will have their own spare cores. For cables with the same starting and ending points and installation units, there are high requirements for the installation conditions of the cables, and Megan cables do not need spare core wires. A small cable can also be used without a spare core.
When selecting a flexible control cable, in addition to the above four main factors, the cable configuration also needs to meet certain conditions, that is, in the case of different installation package units and different voltage and current characteristics, it is ensured that the same cable is not used. Of course, like high-flex cables, flexible control cables are also more flexible, which is an important reason why people choose them.
