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

A lot of ways ah! You look at the back of the set-top box, a total of three kinds of interfaces, namely, HDMI digital signal (while transmitting audio and video signals), red and yellow and yellow chicken complex habit of glycosylation moxibustion slim faint handle (red is the right channel, white Is the left channel, the yellow is the video), the color difference signal (red, green and blue, only transmission video), S terminal (single hole four pin, only transmission video). You just put the video to the TV, the audio to the amplifier on the line. . if your amplifier does not have HDMI interface, then put the set-top box HDMI connected to the TV, the set-top box red and white two terminals, connected to the amplifier red and white input terminal, and adjust the amplifier to the appropriate channel The . if your amplifier has HDMI interface, then through the HDMI series on the line, the first amplifier or the first TV will do. . TV set after a lot of them, there is a group of AVOUT output interface, this group of red and white terminals connected to the power amplifier is also OK.

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: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,

Not allowed to slot the proposal with PVC gusset which is only 1 cm thick only open protective layer on it! The water pipe is not enough unless you have a thickened wall outside the decoration.

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: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

This is too difficult to give you a way to just try: with a fine wire rope, that is, lift the clothes on the stick so thick, the end of a bend, with a tape wrapped around the head, try can not wear, wear When the possibility of rotating wire rope, if you can go through the success of the half, the key is to use the wire through the more difficult, can only use the cord, hard-line 100% make life difficult.

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: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

Galvanized pipe itself with anti-corrosion coating, you can not do anti-corrosion.

Q:What is the difference between wires and cables?

The introduction of the device is to introduce the cable into the electrical equipment, without changing the explosion-proof type of explosion-proof equipment

Q:Rt, the charger did not change, has been no problem before, today just plugged into the charger, the results appear as if the problem, before the out of this problem, and now only ipad power off after the power can not be charged, and ipad start , Then immediately prompted the title, can not charge more

At the same time, security monitoring line itself is a weak line

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
