The automatic cable you understand?
Dianlan P automation cable is one of the cable is very common in life, but do you know about automatic cable?
Automatic cable problem, main is to use before laying the choice of environment is very important, such as: cable trench drainage system to be reliable, don't let the rain water or other water into the cable trench.
Turn up and down, left and right sides of the ditch to considering the minimum maximum cable allows the turning radius, automation of cable grounding bus bar from a certain distance must be extremely, had better be in cable need to grounding protection measures.
Don't let the cable trench inside cross section decrease too much.
N line automation cable theory of allowed maximum unbalanced three-phase load flow should be greater than the sum of current and zero sequence current harmonics.
In engineering are usually in a predominantly single-phase equipment system, N line section is equal to the phase line section.
In contains a lot of zero order harmonic component of the system, N line section is equal to the phase line section of times, or according to the actual need to customize.
Automatic cable laying distance caused by single phase short circuit fault, ground fault protection sensitivity problem need to be resolved.
Automation is parallel operation of power cable, cable to cable two ends connected to the switch contact point contact condition, nose often checks, ensure good cable connected to the switch.
If cable nose with switch contact is not good, could easily lead to the switch in one phase of a cable or a few contact resistance is too large, lead to two cable load flow distribution is not uniform.
Automatic cable must be careful when laying, in accordance with the relevant provisions of the process to avoid operation error.
China cable industry net remind you: in the process of using the cable, we will strictly in accordance with the instructions to perform the operation, to avoid unnecessary accidents.
