Q:Decoration when the purchase of water pipes, wires and other items included in the account

Outdoor fire line must use fire-resistant KVV cable, wear pipe protection.

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

Mainly to distinguish the ground which is the ground, the color of the ground is generally yellow-green; wire two is the fire line L and zero line N, no ground wire, look at the plug on the LN mark, the corresponding good.

Q:Apple phone display cable or accessories not certified how to do

The control cable transfers the electrical energy from the power distribution point to the power supply lines of the various electrical equipment The rated voltage of the power cable is generally 06 / 1kV and above, the control cable is mainly 450 / 750V The same specifications of the power cable and control cable in the production, the power cable insulation and sheath thickness than the control cable thick

Q:IPhone mobile phone data cable can not charge the power, the above shows the cable or accessories not certified can not work with the iPhone,

Wiring room refers to the distribution of the weak floor of the room, the weak point refers to the building weak vertical pipe

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: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:IPadmini. The latest version 7.1.1 up in the morning to see the non-stop display this cable is not certified does not support this feature. The The Charger original. Not on the computer charge. The Ask God to answer more

Ipad charge display does not support the general reasons for this and processing methods: . for non-original charger, it will often appear this situation, which is due to the charger does not meet the specifications caused by the replacement of a qualified charger can be. . if the original charger appears the above failure, please continue to look down. . please check whether the data line is normal. The appearance of the data lines seem normal, which may have been broken. Check the method is to borrow someone else's data line to see if it can charge. . shows the plug symbol is normal is full of display. If full or show the lack of electricity, indicating that the phone tail no problem. . again, check whether the original charger can work properly. You can connect the charger to other USB port to see if the phone is working properly. . if the above two check still can not charge, please try to insert the computer's USB port to see if the computer can identify the phone, to identify if it is to see if the charge, if not identified but not charged, it is estimated that the need for maintenance. If you can not identify can not charge, it is necessary to repair. If you can recognize and charge, replace the data cable and the charger (the original estimate is also damaged). . and then look at the voltage is not too low, not only to the maintenance station to repair, and pay attention to the iPad and iPhone do not mix the power adapter, the voltage is different.

Q:Why does the bird stand on the wire without anything, but if people touch it,

National standard line, no problem. Do not pick up the heater in winter. If not the national standard line, that copper is not easy to go wrong, then use, from time to time touch the line is not hot, there is no problem.

Q:Wire and cable model ZD what does it mean

Put the water clean, with a table to measure the insulation resistance between the lines, as long as no less than 1.5-2 can.
