Q:Is the power cable considered a fixed asset?
To be included in the fixed assets subject, but the input tax is not allowed to deduct. The formation of fixed assets real estate ---- plant.
Q:Ipad charge does not enter the charge does not support this accessory charge
The In general, single-core 15 square wire, for lighting fixtures; single-core 2
Q:Apple mobile phone does not support this charge when charging this thing how to charge
This is mainly to see the tube with a wire, or directly laying in the wall. If the pipe is used BV-type single-layer insulated wire, because it is not required to wear pipe jacket. Such as the direct laying in the wall with BVVB type wire (two wire core, insulation plus jacket) is better, the sheath can protect the wire from external damage.
Q:With a i3-2100 desktop computer about how much money. To have a separate graphics card. Give a configuration alone, no more than 4000
Yellow is the ground, the other two casually, mainly to see when you plug there is the line of fire, no effect.
Q:Why does the AC welding machine burn out the equipment?
Cable bridge spray to improve the corrosion resistance and anti-aging. Spraying the cable tray is the electrostatic powder coating equipment to spray the powder coating to the surface of the bridge, under static electricity, the powder coating will be evenly adsorbed on the surface of the cable bridge to form a powder coating, powder coating layer through the high temperature baking flow Flat and cured, into the effect of different (different types of powder coating effect) the final coating. Spraying effect in 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. The basic principle of electrostatic spray technology is the static generator to produce negative high pressure (10KV or so), the use of corona discharge phenomenon powder coating (a variety of colors) adsorption on the metal parts, powder coating by the supply system by compressed air Nozzle, the front end of the nozzle with a high voltage generated by the high voltage static generator, due to corona discharge, in the vicinity of the dense charge generated by the powder from the nozzle when the formation of charged paint particles, it is the role of electrostatic force , Is adsorbed to the metal parts up, after heating the powder melting, and natural cooling curing, in the workpiece surface to form a hard coating. This kind of spray cable tray is made of this.
Q:Pvc threading tube packaging film how to do attractive, on the grade it? Thank you great god
ZR-KVVRP-500 is mainly used for transmission control, measurement signals and other cables. ZR: Control cable KVVRP: PVC insulation 500: Rated voltage 500 V or less 1 × 2: Two core 1.5: Wire diameter
Q:Ask you a question: how the computer CD-ROM power supply 5V and 12V two lines? Another audio and video cable which group?
My computer --- right-click properties. Device Manager. Look at the USB device is not there or the number. Have to reinstall the system. Also make sure your motherboard USB interface is not good. I said the interface is plug USE jumper of the root.
Q:Brief description of the difference between cable and cable.
Network cable is to take the digital signal, CATV cable is to take the analog signal, how can interfere with each other, do not understand do not see this stare blindly understand the beads. It was all right to be wrapped around with an electrical tape.
Q:What are the varieties of wire and cable (detailed point)
DJ is a distributed instrument signal cable, also refers to the computer cable, V is PVC. The specific meaning can see the manufacturer's product description.
Q:Paint trunking, galvanized trunking: that good? expensive? Their advantages and disadvantages?
Because the AC operation will produce eddy current, will make the steel pipe and cable heat burned. Single core refers to only one conductor in an insulating layer. When the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage. Power safety regulations: 35kV and below the voltage level of the cable are used at both ends of the grounding method, which is because most of these cables are three-core cable, in normal operation, the current flow through the three core sum of zero, in the aluminum There is no flux chain outside the package or metal shield, so that there is essentially no induced voltage at both ends of the aluminum or metal shield, so there is no induced current flowing through the aluminum or metal shield after grounding at both ends. But when the voltage exceeds 35kV, most of the single-core cable, its core and metal shield layer relationship can be seen as a transformer primary winding coil and the relationship between the core. When the single-core cable core through the current when there will be magnetic lines linked to aluminum or metal shielding layer, so that both ends of the induced voltage.
