Q:Emergency cable T-box and cable distribution box of the information?
Cable distribution box according to its electrical composition is divided into two categories: one is not any switch equipment, the box only the cable end of the processing and connection of the attachment, the structure is relatively simple, smaller, more functional , Can be called ordinary distribution box; the other is not only the general distribution of the box annex, but also contains one or more switchgear, its structure is more complex, larger, more connected devices, manufacturing technology Large, high cost, can be called advanced distribution box
Q:The wall was sideways opened a trough how to do ah?
The copper core grinding first to the copper core on the flux (rosin or solder paste)
Q:Which has, know the power of the electrical, choose the cable formulas. And explain it
Basically are refining, the wax is also used, the high cost of particles
Q:150,120,95,50,25,10,4 * 1.5,2 * 1.5 how much cable to use the heat shrink tube
Hard drive is too expensive, not within thousands of dollars. 8 years to open shop experience Hotspot: 1.CPUG530 is i3's Lite, good performance, low power consumption, mainstream interface is. G530 integrated graphics chip, performance as much as ATI3000 series, Lu master test 30 points, equivalent to 200 yuan or so independent graphics card, alone was GT220 test is 60 points. 3. Motherboard is ASL, relatively old brand, this motherboard wiring and materials are good. 4. Xingyu Quan chassis work well, comes with power warranty for three years. Recommended configuration: CPUIntelCeleronG530 / bulk 1 ¥ 265 heat sink Jade Bird III25 yuan motherboard ASL H61U1 ¥ 299 memory KingmaxDDRG1 ¥ 70 hard drive Hitachi Deskstar7K1000.B320G1 ¥ 240 chassis Star Yuquan V ¥ 160
Q:What does ZR-YJV 6mm2 * 3 cable mean?
The initial also said that car 3S brand stores, mainly refers to the front of the three S
Q:PVC pipe line 6 points and 4 points which big ah?
35 square copper wire current carrying capacity is 105A, 105A / 35 mm2 = 3A, (1 square millimeter carrying capacity is 3A) 70 square copper wire current carrying capacity is 169A, 169A / 70 square millimeters = 24A (1 square millimeter carrying capacity is 24A) 1 square hai load current from 11A gradually become 24A So it is impossible to use n by the coefficient can be drawn to the current value Wire can carry the current * the applied voltage * power factor = can drive power The diameter of the wire with different diameter is not the same No specific diameter can not know the current carrying capacity How much power, depending on the voltage level Because P = UI As the saying goes: a square 4 current, underground than this small forget How much is the square here is a square millimeter Power depends on your voltage, the general small line can be directly by 5 is to eat the current to 50-120 the basic can take more than 35 can take 25 or so just personal experience to do reference to the need for basic data: 1 line, copper and iron Aluminum silver temperature 3 core number 4 diameter Probably take a square 5A diameter n square of the wire can be over n high current, resulting in n high power so that can be calculated
Q:TV tiger when the set-top box when tv / ay look for a look on the platform
Do not have to be so troublesome, such a phenomenon even encountered, is the basement of the air defense, similar to the landlord said the phenomenon can be taken as follows: . first with linen live wire and casing blank. . filled with asbestos cement and compaction, the surface concave sleeve 3-4 cm. . with plugging the king (5 yuan / bag) add water and mix well, smear the surface to smooth. . the work is completed, do not hurt the core and the practice proved no leakage within two years.

Do not recommend you use that, if the time is slightly longer, the battery has lost, and the performance is also reduced. You use the notebook, the battery on the inside, even if the charger has been stuck all right. The computer has a battery automatically charge the chip, say the lithium battery no memory effect, but very lazy. If it has been in the active state will be very lively. Storage capacity will always be maintained, on the contrary, the loss of vitality, your battery is a little bit lost, their own look,
