High-flexible cable is a kind of cable with better flexibility.
It has been widely used in household and industrial power, which greatly facilitates people's lives. At the same time, its development has been highly valued by the national power supply network. Flexible control cables, like high-flex cables, play an irreplaceable role in people's lives.
So what factors should be taken into consideration when choosing a flexible control cable?
Generally, shielded cables are used in places with electromagnetic interference resistance, and flexible cables are mainly used in mobile devices.
Because the control cable itself has a small cross-section, it also has high-reliability requirements during operation.
According to the relevant regulations of the industry, most of the cables are copper core cables.
The cables should be properly controlled in diameter during use. It is applied to the diameters of the core sections when connecting the two electronic terminals.
The requirements of the former are generally greater than or equal to 1.5mm, while the latter requires greater than or equal to 0.5mm.
When the cable is in operation, the current and resistance, and voltage in the circuit must be within the specified range.
When it is connected to the secondary side of the current transformer, the cross-section is also checked for correlation.
If it is connected to a voltage transformer, its voltage drop is checked accordingly.
If the meter is used to measure the loop, it must be adapted to the measurement accuracy of the meter, and if it is applied to the billing meter, the voltage drop should be less than or equal to 5 percent of the rated voltage.
For automatic devices, relay protection, and control loops, the first two should not be greater than 3%, and the latter should be less than or equal to 10%.
The more cable cores are generally selected, the fewer the cables can be used when in use.
Moreover, the general cable will have its spare core.
For the cable with the same starting and ending point and the installation unit, there are high requirements for the cable installation conditions, and the spare core is not required for the Meghan cable.
A small cable can also be left without a spare core.
In addition to the above four main factors when selecting a flexible control cable, the cable configuration is required to meet certain conditions, that is, to ensure that the same cable is not used when different installation package units and voltage and current properties are different.
Of course, as with high-flex cables, flexible control cables are also more flexible, which is an important reason people choose them.
