My dog dog special skin, I would like to train it, let it be something! The The (⊙_ ⊙?) Do ah? The More
Above that is almost, there is a very important thing is that the lock must be all copper, and now more expensive copper, and really do this line are known to do the best material is the lock of copper, because the copper comparison Stable, the weather changes he will not lead to mechanical keys can not open the lock, the mechanical key is used in case of emergency, if not open the door that failed ~
The quality of the wire has two main parameters, one is the resistivity, one is the cross-sectional area, the resistivity mainly reflects the purity of copper, the cross-sectional area is mainly to reflect whether the national standard; the market line is a lot of small factory production Of the non-standard line, so I suggest you go to buy the national standard line.
The telecoms are generally routed with large logarithmic cables (more outside) or fiber. The central office room program control on the board side of the wiring cabinet, and then extended to a large logarithm to the district transfer box wiring module. The client side of the telephone line on the user module, through the jumper docking. The large number of wiring modules are usually ordered. When stripping a cable to find a pair of thin lines. various colors. In fact, like heaven and earth in general, five main colors are white, red, black, yellow, purple, there are five auxiliary color is blue, orange (orange), green, brown, gray. Understand the law, you press the main + auxiliary law to check the line or line it. Example 1: 25 pairs of telephone communication lines. The second pair of lines are: white and blue; the second pair of lines are: white orange; third line is: white green; fourth line is: white brown; fifth line is: Red and blue .... twenty-five pairs of lines are: purple gray. recycle. Example 2: 100 pairs should be divided into four groups, each group of 25 pairs, there are two pairs of spare lines, the use of the main color and auxiliary color combination is the line order (remember that the first sub-large, that is, four groups The order of the ribbon, according to the blue, orange, orange, green, brown, and then each group according to the ribbon order white, red, black, yellow, purple five small components.
