Progress
- 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: Apple phone display cable or accessories not certified how to do
- Reply 3 # shops always have the door, and the door must be adjacent to the outdoor channel. Outdoor channel is public space! So the shop should be able to find the wiring channel. You have not encountered the situation, the map stickers out to see it?
- 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: Cable a fire line power and why the other did not pick up the line with a pen test also have electricity? Answer detailed point
- Megohmmeter, such as measuring insulation normal, that is, induction power, the other line after grounding, the pen measured no electricity.
- Q: Wire and cable CCC product consistency is what
- PVC line, the market is better with plastic, plastic, . Wantong, etc., if only home improvement, then the brand requirements do not need so high. Small brands are the same, we see the quality. Network cable, then preferred Ann or TCL.
- Q: Apple mobile phone does not support this charge when charging this thing how to charge
- Charging line and the phone does not match, for the good point of the line just fine
- Q: What is the difference between "wire" and "cable"?
- Inkjet printer is not printed, pictorial machine high definition, generally used in the advertising industry, for large outdoor advertising, the nozzle can choose not necessarily the number of installed, the more spray, spray the faster, a nozzle of the general life 1 year.
- 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: This cable or accessory has not been certified and may not be able to work with this iphone reliably
- Multi-core cable should be cable number, if not, should first use the table to find and put on the line with the tube.
- Q: What are the T and T, s of the wire and cable test type?
- May be charging head of the problem, the line may also be a problem. If the warranty can be free for the change.
