Progress
- Q:Wire and cable: RVFV. : RVFSV. : UTP-CAT5E. : SYV-F-75-5 : RVFSP. : RVSP. : RVFVSP. What is the type of wire? Solve! More
- Pro, please buy in the hardware store turpentine wipe, a bottle of 3.5
- Q:Wire and cable CCC product consistency is what
- What brand of wire pipe PVC pipe used? Is not in the financial or plastic surgery better ah? Guiqiu we recommend, thank you! What brand of network cable used a good, need double shielded cable, thank you
- 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: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
- Bookstore tool book should have "communication project budget", I do is what you say, the budget is divided into estimates and budget, is two steps. So that is not very clear. But what is needed is the preliminary design of the project. The budget is needed for design and drawings. Internal management of this piece, the main thing is that you need to do what the project department, and are generally very complicated
- Q:How to determine how much wire and cable should be used, the current load and how the corresponding wire, such as 4BV, under what circumstances, YJV240 what circumstances, the load is much more
- After the opening is not, if not open like a downstairs to delete the C disk file on the line, if the boot is necessary to set up, sit down little hands and feet.
- 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
- Wire pipe water problem: In fact, this problem is very serious, then this line should be scrapped or replaced, if you continue to reluctantly use not only to bring you the safety of trouble and the insulation of the wire dropped sharply! Because there is water it will lead to internal leakage can also make the wire heat caused by wire burning and trivial trivial accident, so be sure to take the necessary replacement! Supplement: the wire out of all, with the wire to grab the absorbent gauze and the like back to the twitching, many times for the gauze to dry the water, hair dryer toward the tube to heat the tube to dry and then re-layout of the new line.
- 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.
- 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:This cable or accessory has not been certified and may not be able to work with this iphone reliably
- The operation of the hydraulic pipe is very simple to see it will engage in their own, embedded more simple, and then get the construction site in accordance with the requirements of the drawings put away, tied with tie wire on the OK Mouth up the pipe to use cement bag to prevent good, to prevent the infusion of concrete, so buried even if the end
