Q:Home decoration line trough how much money 1 m wall how much money 1 square with brick tiles underwater pipes how much money is not only a lot of money

You recommend the purchase of a monitor package, including a four-way embedded network video recorder, a 1000G monitoring dedicated hard drive, four infrared camera, eight 75-3 video head, 100 meters 75-3 video cable, 100 meters 2 * 1.0 power cable (host power supply) / 4 12V2A power supply (nearest power), the price of 1500-2000 in addition to make a Q9 to Lotus head of the video cable connected to the TV can monitor the network port can be connected to the computer Or the police station for remote monitoring

Q:Who knows home improvement trough is generally playing high ah?

The powder coating will be uniformly adsorbed on the surface of the cable bridge to form a powdery coating. The powder coating layer is flattened and solidified by high temperature baking, and the powder coating is applied to the surface of the cable. Into a final coating with different effects (different effects of powder coating). Spraying effect in the mechanical strength, adhesion, corrosion resistance, aging resistance and other aspects are better than the painting process, the bridge body metal can play a good protective effect, the cost is also under the same effect of paint.

Q:What is the name of this pluggable trunking for this supermarket instead of wire?

Their function is the same, is used in the place of different split fiber box is used to branch the fiber using the wiring box is used in the engine room cabinet terminal box is used in the terminal of the transfer box, generally Used outdoors.

Q:When the interior decoration, the roof on the alignment do not casing ah? At that time the slot is very small, the electrical preparation of bare wire, okay? I have no ceiling

Above do not need to pipe, set a sheath on the line, because the floor are castable can not open the slot, only the ground can have a cement layer slot. Understand

Q:How many specifications are used for domestic wire trunking?

Copper core 5 amps per square meter current, equivalent to 1100w.

Q:Please the architect of the structure of the experts to answer because the beginning did not understand, in the load bearing pillars opened a slotted board, and later said that this affected the structure of security, I would like to ask you how to help remove the experts to remove the plaster, No, how to operate well. More

Can be buried, it is best to use pest control, armored cable and plus casing

Q:H + CMR100 * 100J + AMR100 * 100J + MR100 * 100T + MR100 * 100 above the four codes are what the meaning of MR I know that is the metal trunking, but H + CJJ + AT What is the meaning of it online and so much more urgent

Electrical design specifications for civil buildings · Section 7 · Cable tray cabling Cable bridge multi-layer laying, the inter-layer distance is generally: the control cable should not be less than 0.20m; power cable should not be less than 0.30m; weak cable and power cable Should not be less than 0.50m, if the shield cover can be reduced to 0.30m; the upper part of the bridge from the roof or other obstacles should not be less than 0.30m.

Q:Tedious. I can now use the nail gun to play, but the difference between woodworking is my request can not hit the wall nail head. Do not know what kind of modification method, there is a joint with a pump and a gun down how much money? Pump is the kind of trumpet, looks like the store is 3.. I do not know what the specific meaning. Refused to copy, please use the advice of people, thank you! More

The description on the floor plan is not very clear, except that TD / TV should also have a note on the pipe. If it is marked two tubes, that is separate, if only one is the same line tube. In general these two cables are not in the same pipe, because the distribution is not the same. Each type of building has a certain difference. For example, residential, each TV port should be placed next to a network port, because to be available to users who may use IPTV. Such as office buildings, basically can not appear in one place. Such as the hotel, in addition to the room TV, the other is unlikely to appear in one place. In many cases, the end of a few meters ten meters in the same tube is common, there will be no problem. Because the TV cable is shielded. All hands to play, hope to adopt.

Q:9.7.3 The same route without interference requirements of the line, can be laid in the same metal trunking. The total cross-section (including outer sheath) of the wire or cable in the trunking shall not exceed 20% of the cross-section of the trunking, and the current-carrying conductor shall not exceed 30. I would like to ask where the current-carrying wire is a single-phase circuit in the L line, not including the N and PE line is it? That is, a distribution box leads to more than 30 single-phase circuit, its current carrying wire number is the number of circuits? Is the N-wire not a current-carrying wire? More

N line must belong to the current conductor. If the three-phase load balance, N-line current is . such as imbalance, there is a current through. Such as the third harmonic of the grid serious, N-line current may be greater than the phase current. At this point, the wire cross-section should be the current flow of N line selection. PE line should be non-current-carrying conductor.

Q:The contents of the VAT invoice for the other party: Ming bit alignment system materials, a group. And my unit is the entry slot, switches, etc., how should the invoice should be opened "

. the wire is the conduction current of the wire. . the cable is used to transmit (magnetic) energy, information and the realization of electromagnetic energy conversion wire products. . the wire is made of one or several soft wires, the outer package to soft and soft layer; cable is composed of one or several insulated package wire, outside the package to the metal or rubber made of tough outer layer. Cables and wires are generally made up of three parts: the core wire, the insulating sheath, and the protective sheath.
