What is the difference between power cables and communication cables and control cables? In addition to the communication cable is the line, the communication cable can use power cable or control cable instead or control cable with power cable instead? To predecessors up to people pointing about the three types of cable the difference, and how to choose the cable? Thank you more
Copper wire is generally caused by lightning or large current caused by the first to confirm that the line is copper or copper and aluminum, and now the market a lot of aluminum wire to serve as copper, this line can not afford Heavy load electricity, and the coating is easy to oxidize black, if it is copper and aluminum, then the best change, because the plating of copper has been completely ineffective oxidation. If it is copper and the skin is not bad can not change.
Oh, I am not an electrical professional, but only by experience to talk about, shielding the cable to play shielding the external electromagnetic interference function, the cable must be a single wire grounding, rather than both ends are grounded, that will form a ring current ... ... view Original post & gt; & gt;
You buy is a poor quality line, it is recommended to buy again, safety first
Conductor maximum working temperature of 90 ℃, short circuit temperature (up to 5s) ≤ 250 ℃, the laying of the ambient temperature ≥ 0 ℃ (below 0 ℃ to warm up), laying to allow bending radius: single-core cable is not less than the cable diameter 15 times, multi-core cable is not less than 10 times the cable diameter
