Pro, please buy in the hardware store turpentine wipe, a bottle of 3.5

Q:What brand of cable is good, what are the top ten brands of wires?

Power circuit box, the home of the circuit is divided into lighting, walls, air conditioning, etc., there is the bathroom and the kitchen line and the separation of the room.

Q:Why this cable has not yet been certified

The manufacture of wire and cable is completely different from that of most electromechanical products

Q:What is the difference between the WDZ wire and cable, the ZR wire cable and the NH wire and cable, and what kind of wire and cable should be used?

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:What is the difference between "wire" and "cable"?

Simple point, the plotter is generally used to out of the line map, the general is the Academy of Engineering, the Bureau of the use of a CAD map, and some can also be some effect of the general effect of the map, generally suitable for color requirements are not very high, but right Print accuracy requires a high place. Inkjet machine can be divided into indoor and outdoor ink, outdoor irritating smell, for outdoor advertising like the effect of the map, the indoor no irritating smell, the general subway, as well as other indoor advertising are used this out of

Q:Four lines only reached a phase line, at the other end all charged, I use the digital pen! In addition, I often check the cable when the cable current through the dot digital pen voltage symbols sometimes have time to disappear, in other bare wires when the test keys are normal! What is this going on! Ask the heroes to give the younger brother a complete point of the answer! More

Bookstore tool book should have "communication project budget", I do is what you say, the budget is divided into estimates and budget, is two steps. So that is not very clear. But what is needed is the preliminary design of the project. The budget is needed for design and drawings. Internal management of this piece, the main thing is that you need to do what the project department, and are generally very complicated

Q:How are various wire and cable models named?

Cable type a lot, here to give an example: ZRC-YJV22-0.6 / 1KV3 * 25 +2 * 16 This model specification means: C-class flame retardant (ZRC) XLPE insulated (YJ) PVC jacket 22) steel tape armor (0.6 / 1KV) 0.6 / 1 kV (3 * 25) 3 25 square (+ 1 * 16) plus two 16 square copper conductor flame retardant copper core steel tape armored cross-linked poly Ethylene insulated PVC sheathed low voltage electric power.

Q:This cable or accessory has not been certified and may not be able to work with this iphone reliably

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
