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

(The difference between the two cables: WDZ and WDZC are the combustion characteristics of the cable, both halogen-free low smoke flame retardant cable, but the former is a single vertical flame retardant test, which is bundled combustion C class flame retardant Test, but the flame retardant performance requirements are not the same. The meaning of the letter: W refers to the halogen-free; D refers to the low smoke; Z refers to the flame retardant WDZ is halogen-free low smoke flame retardant jacket power cable. WDZC refers to halogen-free low smoke C-class flame retardant reference )

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

and then the audio cable and video cable [audio line (red and white), the first time the signal line (white) Video line (yellow)】 corresponding to the color connection set-top box with TV

Q:What machinery is required to make wire and cable?

Line pipe is poured before the concrete is laid on the cloth, fixed on the template or steel, pouring a need to install a class at any time to adjust its position!

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,

You are not very clear: how to start again? 300μF capacitor is normal? If the sound is normal (very small) after no-load start, the cable and the motor temperature are normal, the coil can be judged to be normal

Q:If you want to sell wire and cable, then what to do in advance to detect? The The The The The

Wire diameter, conductor resistance, insulation diameter, the thickness of the thinnest insulation,

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: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?

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.............................................

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:Apple 6 Charging Why always show this cable has not yet been certified

Cable and cable distinction In fact, "wire" and "cable" and there is no strict boundaries

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
