Q:How to connect the desktop computer to the TV can also see ah
Remove the cable itself. If it is 22kV below the infrastructure project. Laying cables. As long as the cable T is connected to the tower (rod) in the exposed part of the protection tube should be installed. Under normal circumstances: are PE pipe laying cable. If there is a cable trench on the use of PE pipe. Ibid, bridge, overhead, etc. are not used PE pipe.
Q:What is the use of fiber patch panels, where to apply?
1. Birds are just standing on a wire can not form a loop so there is no electric shock. 2. Birds feet from the distance even in the high voltage line will not form a step voltage.
Q:How can the most effortless way to put the cable on the bridge
All right, Apple's power adapter voltage is 110-. where can be used, the power plug is also the same with the domestic, are the two the kind of (extension of the line with the head) and the same
Q:How do I eliminate the interference of the frequency converter to other electronic devices?
Is it your own phone's own data cable? If the line and the charge head to determine the problem, that is, mobile power problems, you can contact the seller to repair or replacement
Q:Wire production is not to be a few meters ahead of the extension line

Q:Is the POE switch connected to the network camera via the patch panel to affect the power supply function?
It is best not to open the hole from the bottom of the bridge, if necessary, do the mouth to do sealing treatment to prevent the bridge from the mouth of the water poured into the power distribution device.
Q:On the same ditch laying high and low voltage cable doubts?
PVC pipe 6 points of course, more than 4 points in large, the score is in English, every 8 points is 1 inch, equal to 25.4mm, it represents the pipe diameter. 4 points corresponding to the tube diameter of .6 points corresponding to the tube diameter of .1 inches corresponding pipe diameter of 32. PVC type pipe with PVC pipe with PVC pipe has PVC electric tube JG / T3050-1998PVC electrical casing classification, divided into L type (light) M type (medium) H type (heavy) First, the implementation of standards: JG / T3050-1998 Second, the product specifications: divided into light -. medium -. heavy-type -405 three. . light -205 outside diameter ¢ 16mm- ¢ 50mm. medium -305 outside diameter ¢ 16mm- ¢ 50mm. heavy -405 diameter ¢ 16mm- ¢ 50mm Third, the nominal diameter were: .... . the thickness of the product is as follows: .16 outside the light, medium and heavy thickness were: 1.00 (light, allowable difference +0.15), 1.20 (allowable difference +0.3), 1.6 (weight, allowable difference +0.3) The The medium and heavy (no light) thickness of the outer diameter of .20 are: 1.25 (medium, allowable +0.3), 1.8 (weight, allowable difference +0.3). .25 outside the diameter of the weight (no light) thickness were: 1.50 (in the allowable difference +0.3), 1.9 (weight, allowable difference +0.3). The light, medium and heavy thickness of the outer diameter of .32 are: 1.40 (light, allowable difference +0.3), 1.80 (medium, allowable +0.3), 2.4 (weight, allowable difference +0.3). .40 outside the light, medium and heavy thickness were: 1.80 (light, medium, allow the difference +0.3), 2.0 (weight, allowable difference +0.3). Fourth, the national standard wall thickness 16: I20: 1.125; 1.332: 1.540: 1.950: 2.263; 2.7 These are more commonly used.
Q:4 pipe more than 6 cable What should I do?
Wall wear wire tube recommended with a diameter of 20mm. Too fine to heat up.
Q:Brick and concrete structure of the wall and roof how to embed wire tube? The
If there is no wall, you can in the wall when the embedded tube, if it is already a good wall, it is necessary in the wall slotted wiring, how to do depends on your wall status.
