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: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...........................: I think it is possible, because in our (old) substation, the cable trench is the drain, the cable erected in the cable bracket.

Q:The data line is my online to buy the extension of the line, has been able to use, and today suddenly can not charge the electricity, and pop up the tips, which is why? More: What do you want to do? Do network cabling buried? Or in the building after the tube?

Q:What is the difference between "wire" and "cable"?: Simple point, the plotter is generally used to out of the line map, the general is the Academy of Engineering, the Bureau of the use of a CAD map, and some can also be some effect of the general effect of the map, generally suitable for color requirements are not very high, but right Print accuracy requires a high place. Inkjet machine can be divided into indoor and outdoor ink, outdoor irritating smell, for outdoor advertising like the effect of the map, the indoor no irritating smell, the general subway, as well as other indoor advertising are used this out of

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: According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.

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 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?: Make a mark, such as red set into the bottom for a color in a layer, or you can draw a few plans, water and electricity is a strong power is a weak and one, the label can do a good job

Q:Engineering materials inspection, all types of cable wires should be issued a test report?: You look at your TV behind the interface dvd are generally with the color of the port (green red and blue) interface you dvd the best copy of the flowers deduction ditch dumplings evil spear that interface on the LCD TV certainly with that color interface so that your set-top box Then the av interface (yellow) video port on the line there is a way set-top box with a terminal is the same as the mouse with the same interface with the mouse with the video port plus two voice interface on the line that is better than the av interface can also solve the problem LCD TV certainly Will take that interface you look at the set-top box and dvd have any different interface on the use of the impossible can not only two mouth it (yellow interface) and 40-inch LCD TV is generally high-end are generally two An av channel input you are inserted two lines are also ah

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: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: casing filled with dry cement, and with a wooden hammer tamping, but a certain idea of security, high pressure line once rammed the skin is too dangerous, should be done before power, you now estimated to have power,
