Question:

Four air-conditioning, two electric water heaters at the same time need to use the number of square wires

Color line, coaxial line, HDMI cable, S-terminal line between the difference, can transmit what signal, audio or video?

Answer:

If only for general use, then, or can use BV, and no special needs, then, with AF is too wasteful, and also play a role, and that money is not necessary. AF use one: aircraft wiring, electrical appliances, telecommunications equipment and instrumentation lines. Second, the use of temperature: -60 ℃ ~ +250 ℃
The patch panel is a device for terminating and connecting components (such as a distribution panel, a plug cord) to a cable or cable element
AF high temperature wire for AC rated voltage 450 / 750v and below electrical equipment, instrumentation, power plants and lighting lines, such as the use of line connection. Long-term allowable working temperature should be more than 70 ℃, laying ambient temperature should be lower than 0 ℃. Laying installation to allow bending radius should not be less than 6 times the cable (wire) diameter; diameter less than 25mm below the cable (wire) should not be less than 4 times the cable (wire) diameter. BV general purpose single core hard conductor without sheath cable can be seen from the introduction, AF suitable for use in many specific circumstances, the price is certainly more expensive than BV.
