I am a science and engineering, some people think that disk will be hot. I think this is not the case, I think the disk has no effect, the wire is the AC current, inside the two lines of the current direction at any time can be offset each other to produce the electromagnetic effect. I think so, I hope a professional person to make a professional and detailed explanation. More
No, the disk will lead to heat accumulation, the impact of wire cooling, serious will burn the wire, especially in the maximum current carrying capacity when the wire is more obvious, so the use of wire tray up to no more than 1/2 rated current, "The inside of the two lines of the current direction is always the opposite can be offset each other to produce the electromagnetic effect" This is very right, the use of wire tray will not increase the wire impedance, but not a single wire, must be the same Two of the circuits at the same time disk up. Wire: the wire is made of one or several soft wires, the outer package is soft and soft; the cable is made of one or several insulated packets, and the outer layer is covered with a tough outer layer of metal or rubber. Cables and wires are generally made up of three parts: the core wire, the insulating sheath, and the protective sheath. Commonly used cable features are as follows: CEF - EPR insulated neoprene jacket, marine flame retardant power cable. CVV - PVC insulated, PVC sheathed marine flame retardant power cable. OVC cable commonly used BV, BX, RV, RVV series of wires, including: BV - copper core PVC insulated wire, long-term allowable temperature 65 ℃, the minimum temperature -15 ℃, working voltage AC 500V, DC 1000V, fixed laying In the room, the outside can be deposited can also be deposited. BX - copper core rubber insulated wire, the maximum temperature of 65 ℃, apply to the room. RV - PVC insulated single-core cord, the maximum temperature of 65 ℃, the lowest temperature -15 ℃, 250V AC voltage, DC 500V, for the internal wiring equipment and equipment. RVV - Copper core PVC insulated and sheathed flexible wire, allowing long-term working temperature of 105 ℃, working voltage AC 500V, DC 1000V, for wet, mechanical protection requirements, often moving and bending occasions.
In fact, Tian Min network set-top box on what TV are the same, the TV only acts as a display of the role.
Wire to make a new line? Have not heard of it. Installed in the outdoor wall of the wire, rainy day often rain did not say to change the new line.
