Q:What is the position of the wire in the wall?
On the patch panel down the need to pick up the switch to the optical module or fiber optic transceivers and then access the network router, the enterprise then take the general level of general business users on the line
Q:Yjy cable yje and yjv which one is expensive and its own characteristic
You buy the wire is what brand, go online to check, if not the cottage version of the original purchase to swap.
Q:30kw how much cable and switch to use
Current 50A wire VV or YJV223 * 10 + 1 (30 meters) switch 100A (consider starting current)
Q:How can improve the speed, configuration, what can be under what, to move the network line to say
Air conditioning according to the calculation of 1.. the water heater each calculated by 2000W, respectively, to discuss: 1) air conditioning and heating and heating is not open and with two water heaters at the same time the current is: (1100 × 4 +2000 × 2) ÷ 220 ≈ 38A At this time the bus should use at least 6 square copper wire; 2) air conditioning to open the auxiliary heating and heating with two water heaters at the same time the current is: 2000 × 6 ÷ 220 ≈ 55A at this time the bus should use at least 10 square copper wire. So from the home point of view, you should choose is 10 square copper wire. Supplement, household wire diameter selection and power correspondence
Q:How the satellite receiver and the DVD are connected to the TV at the same time
To find a water technician asked a question or to the property to ask also line
Q:Why the three-phase or single-phase AC single-core cable, not alone in the steel pipe
to determine the direction: According to the building layout plan, combined with air conditioning lines and electrical pipelines and other settings, easy maintenance, and cable routing to determine the cable bridge the best route
Q:Bridge 380V strong wire, and now put into the cable to the signal interference?
Design the fire with other weak cable when the separation away, the fire bridge and the weak system of the bridge in principle is to be separated. Fire bridge and weak system of the background music broadcasting system, like a bridge, is a fire effect, for emergency broadcast purposes, it is not recommended with other weak system with the pipeline laying
Q:Is it necessary to protect the buried cable? What position is needed?
Do not specifically do maintenance, will be miserable, with the point of doing the hardware or software sales can also do things such as Internet cafes system maintenance and wiring and the like, start the fund is not very high, only the accessories as long as the common model accessories There are on the line, maintenance test tools also can not spend much money.
Q:How much air does the air conditioner use?
I am not professional, I am learning English, 1 about 732W it is not clear, should be able to use it, but you can ask the mechanic, installed meter asked, or you can ask You may know the door, but you still have to ask about the people who installed the meter, insurance a little.
Q:Will the HDMI cable only output video, and let the speaker output audio?
You do not tell me that you do not have that white box transformer. The The The This is the transformer
