Q:What are the varieties of wire and cable (detailed point)

Cable regardless of the definition of the number of elements in the definition of a few such as: YJV-3 * 50 + 1 * 16 calculated the number of lines is always a different, different wire rules Model input: bv-2 * 2.5 / bv-3 * 4 (different material), bv-2 * 2.5 + 3 * 4 (the same material)

Q:Do not know why not mislead. The The The The The Fire resistance is IECGBBS6387. GB is the general principle of flame retardant and fire resistant wire and cable, quoted the above criteria...........................

I think it is possible, because in our (old) substation, the cable trench is the drain, the cable erected in the cable bracket.

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?

BV1 * 2.5 is a 2.5 square line. 2 * 2.5 is two 2.5 square lines. 3 * 2.5 is three 2.5 square lines. 4 * 2.5 is the 4 2.5 square line lighting wire power cord with 2 * 2.5. Light wire with 1.5 is enough. Socket (pipe) with three 2.5 square lines, you can also use 3 * 2.5 a. 4 * 2.5 for three-phase motors.

Q:Apple 6splus charge may not support this accessories how to do more

When the lighting circuit and the power circuit shared ladder, BV line is not allowed to put in the ladder, so it is recommended to use the wiring of the lamp ZC-YJV-3 * 2

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.

Q:How to determine how much wire and cable should be used, the current load and how the corresponding wire, such as 4BV, under what circumstances, YJV240 what circumstances, the load is much more

Can not be removed, and so on after the first line of fluoride, and then demolition of air conditioning.

Q:Remove the computer and wash it off. What the motherboard did not move it, that is, the dust of those dust sasses, as well as the other wire of the skin what Sassafras wash, but the computer re-connected to the Internet when the old mistakes . and the lower right corner of the red Fork appears, disappeared after the emergence. The The Said the network cable is not plugged in, but the MODERN that POWER, LINK, LINE, 3 lights are normal display. The The This is how the matter, and just also appeared keyboard and mouse just start the machine can also be used normally, but in a moment to fall, and then plug their plug re-plug the mouse lights can be displayed, but the lights on the keyboard simply do not Bright, restart the computer but good, what is going on? bother. The The I hope the master quickly to help me, and this machine is relatively old ah No problem added: on a machine, just tried to re-create a connection in the network neighborhood, useless more

And I answered the other person's question is very similar: . the line of the banding distance of not more than 1.2 meters, the two ends of the wire box outlet tube 15CM should be ligation; . casing embedded, then through the basement wall, the surface must be installed rigid Waterproof casing, that is, steel pipe + water ring; through the fire pool, living pool: flexible waterproof casing; (wing ring specific practices can be collected online related Atlas); through the floor, according to whether the design requirements , Under normal circumstances PVC casing on it. Note: . rigid waterproof casing, flexible waterproof casing is a one-time reserved in place, through the floor of the casing of the flower lamb to suppress the barge of Xi Jie Xi Xi shou, is the first stay hole, when the installation of riser Casing, because the floor casing has every layer, the location of the reservation will always be biased, in order to ensure vertical vertical pipe, and finally unified hanging line repair hole and then install the riser and casing. . now most of the bathroom are dirty, waste and diversion, and more of the riser, and so on, the air conditioning casing of all the shear wall should be embedded, to avoid the subsequent damage to the structure of drilling (no stay can only drill) Note that the location of the hole and the installation of the riser will affect the opening of the toilet window. . the casing is the casing, riser is the riser, casing than the riser model 1 to 2 level. . plate at the end of flat, board 2 to 5CM higher to see if you need to do leveling layer.
