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

Power circuit box, the home of the circuit is divided into lighting, walls, air conditioning, etc., there is the bathroom and the kitchen line and the separation of the room.

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:I would like to ask my new workshop power consumption of about 500KW, injection molding machine, 60KW . 40KW . 20KW . the other 20KW, how much should the wire? Respectively how to use lines and switches more

No way to save money! Moreover, the signal to you there, almost all attenuation finished.

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?

BV1 * 2.5 is a 2.5 square line. 2 * 2.5 is two 2.5 square lines. 3 * 2.5 is three 2.5 square lines. 4 * 2.5 is the 4 2.5 square line lighting wire power cord with 2 * 2.5. Light wire with 1.5 is enough. Socket (pipe) with three 2.5 square lines, you can also use 3 * 2.5 a. 4 * 2.5 for three-phase motors.

Q:Engineering materials inspection, all types of cable wires should be issued a test report?

This approach is a lot of the general is to extend the city line, that is, line 220V AC line lengthened, some in Taobao. 2. to extend the low-voltage line, engage in a power plug on the plug, the same set of seats, you can easily do an extension line, when you want to use, docking about it, when you can not close up. This is also on Taobao, when to buy, pay attention to the socket, plug the model to the on.

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: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
