Q:Will the cable voltage tolerance, such as 450V / 750V, whether it is 450V RMS, 750 peak? Thank you!
The idea of the landlord is really creative. In fact, it is not difficult to do it, hands-on ability to do a little bit of their own power to start the line, replace the original line on the line. But must pay attention to the heat show is not summer, the temperature is too high will burn the host.
Q:How to calculate the wattage wattage and power of the wire?
This is more professional, it is necessary to know the line, there are to know the number of roots, as well as the thickness of insulation, etc., must also have information to check, I suggest you better buy GB products, but also assured, safe, but also worry The Why not do it! The The
Q:What is the difference between a photovoltaic cable and an ordinary cable?
Newly labeled TC, refers to the thin-walled wire tube Above the commonly known welded steel pipe New label, PC PVC tube FPC semi-hard tube KPC corrugated pipe CT, for the bridge laying SC is the meaning of steel pipe wiring
Q:What can I do with electrical engineering and automation? Do not be too professional terms
Cable to wear a metal tube is a fixed cable, the second is anti-interference, the third is the pressure, four is moisture. Because the cable is long and not often replaced, the metal conduit is designed to increase its life. Wire, then do not wear metal pipe first because the wire is mobile, and sometimes will be distorted and the like, so generally do not use metal.
Q:Patch panels, cable management planes, and jumper frame What is the difference between the three? And in what aspects?
6 * 39520 support / bag 1770 kg / bag BAUER JDG / KBG threading tube 16 * 0
Q:What are the requirements for the construction of electrical wiring
Y polyethylene vpvcP copper shielded P2 copper tape DJ electronic computer
Q:Home improvement of the threading tube is not long how to pick up
Should it be a copper power cable? Only the corresponding voltage level of the insulation tape, etc. to the cable three (four) core, respectively, to distinguish the sequence of the package up to avoid the cable inside the moisture and affect the insulation
Q:TV and set-top box component connection with the general yellow and white audio cable can you?
. first check the wire and the data line are inserted firmly. . to exclude this problem. The chassis to open, if the graphics card is not integrated, then pull down the graphics card, rubbed with gold rubbed finger, memory is also the operation of what. Look good or not. . if it is not easy to use, check the motherboard is abnormal, focus on whether the capacitor protrusion. If you can not find a computer can find the dealer to do the following motherboard test.
Q:Where is the battery bus positive and negative wiring harness received?
If long-term leakage is able to reach the pipeline humidity is too large, then the leakage switch can also be out of the gate. Single will not break.
Q:What are the requirements for cable laying distance?
Where, when the cables cross each other, the high voltage cable should be placed under the low voltage cable Special circumstances should be implemented in accordance with the following provisions: 1) l0kV or more between the power cable and the control cable or between the use of different departments of the cable, when the cable through the pipe or separated by a partition, the parallel clearance can be reduced to 01m, 2) Between the power cables, between the control cables and between them, the cable between the different use departments shall be reduced to 025m3 when the cable is perforated or separated by a partition before and after the intersection Cable and heat pipe (groove), oil pipe (groove), combustible gas and flammable liquid pipe (groove), thermal equipment or other pipe (groove), although the clearance to meet the requirements, but may damage the cable during maintenance Protection should be taken within the range of lm before and after the intersection When the cross distance can not meet the requirements, the cable should be inserted into the tube, the clearance can be reduced to 025m4) Cable and heat pipe (groove) And thermal equipment parallel, cross, should take thermal insulation measures, so that the temperature of the soil around the cable does not exceed lOC
