Q:Why this cable has not yet been certified
Electromechanical products are usually used to be assembled into parts, multiple parts and then assembled into a single product, the number of products or the number of pieces measured
Q:A five-hole dual-socket how to connect the wiring, the electrician line to go three lines, the switch can use a single socket did not take their own hands
This is too difficult to give you a way to just try: with a fine wire rope, that is, lift the clothes on the stick so thick, the end of a bend, with a tape wrapped around the head, try can not wear, wear When the possibility of rotating wire rope, if you can go through the success of the half, the key is to use the wire through the more difficult, can only use the cord, hard-line 100% make life difficult.
Q:Fiber optic cable split box, integrated wiring box, cable terminal box, cable transfer box difference
Outdoor fire line must use fire-resistant KVV cable, wear pipe protection.
Q:Is there a difference between PE cable and PE water supply pipe?
Labor costs you can and workers to discuss, and some labor costs are calculated in accordance with square meters, and some are calculated in accordance with the day, the specific or ask the local construction team
Q:When pouring concrete is how to put the tube
Pouring concrete when you can line? Do you clear the problem?
Q:Building decoration wiring pipe elbow with yellow wax tube can you?
Reply 3 # shops always have the door, and the door must be adjacent to the outdoor channel. Outdoor channel is public space! So the shop should be able to find the wiring channel. You have not encountered the situation, the map stickers out to see it?
Q:Connect the computer to the TV. The The Using the HDMI cable. The The Line no problem. The Why not even after the audio video. The The Amplifier is Denon 1311
Make a mark, such as red set into the bottom for a color in a layer, or you can draw a few plans, water and electricity is a strong power is a weak and one, the label can do a good job
Q:The computer can not open the machine display frequency beyond the scope of the mouse and keyboard do not start can not press F8 how to do
According to the "Power Engineering Cable Design Code" GB-. 5.3.3 only asked for the depth of the cable buried directly: drop the blue skin to the ground depth, not less than 0.7 meters; when located in the roadway or farmland Under the appropriate should be deepened, and should not be less than 1.0 meters. 5.4.3 protected pipe buried in the ground, should meet the requirements under the depth of the pressure and environmental corrosion resistance. Through the uneven settlement of the backfill section and other places to increase the force, it is appropriate to use steel. Another direct burial should be selected armor type.
Q:What is the cable for rvv? Is it a power cable or a control cable? What is the cable?
The installation process is a certain requirement, high and low voltage cable bridge should be installed separately as usual, a wall laying vertical pipeline (slot) or installation equipment, the power distribution between the depth of D1 = 1200 ~ 1500mm; weak Between the deep distance from the D2 = 1100 ~ 1400mm more reasonable. The length L1 and L2 between the power distribution and the weak can be determined according to how much electrical equipment and pipelines (slots) are installed in the room. "Civil building electrical design specifications" proposed "shaft size in addition to meet the wiring spacing and terminal box, distribution box layout must be the size, but also in the box before the left not less than 0.8m operation, maintenance distance" requirements. In the weak equipment, the operation and maintenance distance is not specified in the provisions of the Code for Electrical Design of Civil Buildings, but it should not be less than 0.8m. Cable to wear steel pipe wiring, should be reserved in the floor steel pipe, wiring should be completed after the plug fire fire blocking material. Cable bridge installation should be horizontal, the maximum sag should not be greater than 10 mm; proposed separate installation
Q:Home leaked, installed in the floor below the wire was blisters will have any security risks? How can the water inside the pipe to dry
Cable is a unified call, including power cables, communication cables, etc., I do not know what type of cable you need the type specifications. On the power cable in terms of the main models are: VV, BJV, VV. BJV. . ZR, NH and other models, as the specifications that too much.
