What line is the security monitoring power line?
In some cases,.3 root leads to RVV3*X are also usedIn the construction of rigorous design, it is best not to use ordinary civilian electrical lines, one is different and without protective sheath, twist, resistance to electromagnetic interference is not good.
Note that copper wire is twisted, RVV2 two wire within *1.0 or 2, that is the line diameter, line size according to the case design and calculate the size of the load current, decided to use much of the wire diameter.
Standard monitoring power line, AC DC common RVV2*1.0, RVV2*2.0.....RVV is copper core PVC insulated, PVC sheathed cable,
