Q:Will the two 16 square copper wire with what specifications of the trunking
How to say that interference is certainly some, if you line less words on one or two in the bridge next to do a tube it! The pipe will be a little better. Upstairs that I do not think that although in practice the construction of this practice a lot, because you do not feel the interference, but the reality does interfere with, or science should not be strong and weak must be separated.
Q:1.2 meters below the road can use pvc tube wear armor cable?
Have to fight trumpet, mainly to protect the cable jacket is not scratched
Q:What is the difference between public relations firms and media companies?
What is the lighting type busway ah, long experience. Lighting distribution box dedicated busbar?
Q:What is the installation specification for the cable tray bracket?
Be careful is right, but it is not necessary to be timid. Need to do so: . ask the district property, if the best road distribution map, read the drawings, you know where the cable, where not. . ask your home decoration of the electrician, he knows the most where your house where there is a wire decoration. . the general wall cabinet installed relatively high, as long as the bottom of the socket to avoid, generally all right.
Q:Power cable casing buried what are the requirements
2 direct laying cable way, should meet the following requirements: 1 cable should be laid in the trenches, and should be along the length of the cable on the next, next to the side of the shop with a thickness of not less than 100mm soft soil or sand 2 along the length of the cable should cover the width of not less than 50mm on both sides of the cable protection board, protective board should adopt concrete 3 urban cable buried in the laying, it is appropriate in the protection board laying eye-catching signs 4 in the suburbs or open areas, along the cable path of the line spacing of 100m, corner or joint parts, should be erected obvious signs or signs 5 when the use of cable through the corrugated pipe laying in the trenches, should be along the full length of the bellows casting thickness of not less than 100mm of concrete, the width should not be less than 50mm outside the tube, the cable can not armor 3 buried in the non-frozen soil area, the cable embedding depth should meet the following requirements: 1 cable to the basement of the basement structure, not less than 03m 2 cable skin to the ground depth, not less than 07m; when located in the carriageway or farmland, should be properly deepened, and should not be less than 10m 4 buried in the permafrost area, should be buried below the permafrost layer, when not buried can be buried in the soil drainage of dry frozen soil or backfill, but also take other measures to prevent damage to the cable The 5 Directly laying the cable, is strictly prohibited in the underground pipe is just above or below The minimum distance between cable and cable, pipe, road, structure, etc shall be in accordance with Table 535 Table 535 Permissible minimum distance between cable and cable, pipe, road, structure, etc (m)
Q:Hello, ask about how to charge the electric car at home, use a few square millimeters of wire? How high is the demand for family lines, thank you!
What is the current good computer configuration on the market? The price of 4000 yuan or so no more than 4000 assembly parts to write down the price Thank you.
Q:What is the difference between the control cable and the compensation cable?
The reason why the wire outside the casing, is to protect the wire insulation from external damage. And the wire laying in the cable tray. The bridge has been gas to the protection of the role, so no longer outside the casing
Q:Fourth, what causes the power cable fire accident
Once the cable in the event of fire, the fire ferocious, rapid spread, in the burning will occur when a large number of harmful gases, resulting in fighting difficulties
Q:Can cable TV signal lines and network cables be placed in the same line when upgrading? What happens if you are in the same line? Thank you.
Your USB cable is really different. People are red and black is negative, green and white is the data transmission.
Q:Emergency cable T-box and cable distribution box of the information?
The incoming and outgoing wires are electrically connected together The potential is the same, which is suitable for tapping or branch wiring It is common practice to add the number of lines back to the number of times The three-branch cable splitter box, which has three equipotential bonding points on each phase, can be used as a second or two-in-one Cable distribution box contains U, V, W three-phase, three-phase circuit structure is the same, along the row together 2 High-level distribution box High-level distribution box containing switching equipment, both from the ordinary distribution box of the tap, branch, but also from the power supply circuit control, conversion and change the mode of operation The switch fence roughly divides the cable circuit into the inlet and outlet sides, and the potential on both sides can be different The switchgear itself has a larger volume, so the high-level distribution box size is relatively large, the height is generally 14 ~ 18m, the depth of about 09 ~ 10m, the length of the number of switching devices according to the number, M to 24 m The shape of the box is similar to that of an outdoor box transformer, and there are a number of active doors on the shell Some doors are designed for the operation of the switchgear Some doors are provided for the installation or maintenance of the cable connection device The
