RVV-PVC sheathed PVC insulated flexible cable is a wire or cable or a power cable? How to calculate the carrying capacity? Or who is to provide a current carrying table. Thank you all for more
Distinguish between the wire and the power, the prefix wire U is less than 1KV, the prefix power is the opposite is greater than 1KV (the former maximum voltage of the latter minimum voltage), RVV belongs to the former, the jacket wire shop for sale!
And from 3 to 4-axis between the first junction box lead all the way to the bottom (below the drawings of the light box) concrete column, down to the control switch box, this way is the switch control line has three wires (a power cord , Two control lines) is a double open single control switch Finally there is a route between 3 and 4 axes between the first junction box leads to the lower living room (in front of the staircase) other basic basic, wire tube specifications materials can be found in the electrical system diagram and design instructions
Buy a CD-ROM drive / audio output. But the video does not know it!
Cable can be parallel with the 10kV power cable laying, there is no distance requirements, the two cables walk in a metal bridge is no problem, the cable is through the optical communication, the power line of electromagnetic waves will not have an impact, there is no electrical corrosion Problem, because the cable is protected by an outer sheath. Now in the high-voltage cable directly attached to the internal fiber and power supply and communication, but also in the high-voltage overhead lines directly on the composite fiber (OPGW), while the power supply and power grid communication. So, do not have to worry.
