A) conductor (WTC pair with cross section area of at
least 0.5mm2 or 20AWG); B) insulator; C) Screen
layer (twisted WTC with a screening factor no less
than 95%) ; D) Outer jacket (PVC);
Note:
Better choose network cables with a tenser
shielding layer and smaller twisting distance.
Please refer to the UL2547 or UL2791 wire
specification.
The control wire must not be longer than 1000
meters.
The control wire must be at least 20cm away
