Q:How to connect the power cable pre-branch connector
In the pre-measured size cut out the jacket and insulation, according to the different cross-sectional size of the cable cut the size of the jacket and insulation different; with C-shaped tube corresponding to the corresponding color sequence crushing the trunk and branch lines, crimping attention to crimping The strength of the clamp, can not be too loose or too tight, too loose will cause the cable crimping off, resulting in open circuit, crimping too tight will break the conductor or cause the conductor stranded in the contact with a good conductor with polytetrafluoroethylene With the winding baking transparent, and then wrapped waterproof tape (tiger belt) can be used after the wooden hammer shrink the cable core to facilitate injection molding in the injection process should choose the appropriate mold and injection molding machine injection mold injection, the mold is too large cost Waste, the mold is too small caused by defective, bad seal at both ends of the running coke, affecting the injection effect
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:Hello, ask about how to charge the electric car at home, use a few square millimeters of wire? How high is the demand for family lines, thank you!
PLC and computer communication cable, different manufacturers of PLC connection is not the same
Q:What is the interface between the power interface and the hard disk?
10KV generally in the bottom, 380V power cable in the middle, control cable and cable at the top
Q:Power cable 5-color line, respectively, what color, what role?
YJ: cross-linked polyethylene insulation V: PVC sheathed 22: steel tape armor 8.7 / 15KV: rated voltage: 8.7 / 15 kV 3 * 300: three conductor cross-section of 300 square copper conductor Another: such as YJLV Is the aluminum core. Here is not marked what the material is conductor, you can default to copper conductor.
Q:Whether the interior decoration is the first brush latex paint or the first installation of the wire (the line, with the trunking)?
3 + 2 and 4 + 1 are the number of cores of a cable, a cable inside is not a line, is insulated with each other 2 or . 3 +. 4 +1 line, 5 lines , Respectively, called 2 core or 3 core, 3 +2 core, 4 +1 core, 5 and other core. 3 + 2 cable 3 is the three phase lines, the diameter of the line as large, 2 is the zero line and the PE line, the diameter of the line as large; 4 + 1 cable 4 is the same as the three lines and the same diameter, 1 is the PE ground wire is a separate diameter; five core is the phase line, zero line and PE line are the same diameter, 2 core and 3 core is also the diameter of the line. In the end with a few cable, the design specifications are provided! A few words are not clear!
Q:30 on the large number of cable how to fight on the 110 patch panel, how to order, please inform, thank you, which
I have to integrate a graphics card, you buy a separate graphics card is really a waste of money now I also listed, showing a lot stronger than the 2100 performance, and the market in the low-end discrete graphics upstairs you upstairs a lot of results Even a display did not give people with the price exceeded
Q:How high voltage armored power cable is grounded
Insulated isolation of the double shield control cable is the outermost armor layer should be grounded at both ends, the inner shield one end of the ground, is conducive to the rapid release of induced current.
Q:What are the lines that need to be set up for notebooks?
Trough is not conducive to heat, tray heat slightly better There is a cooling hole in the bottom of the tray tray Due to open the cooling holes, tray-type bridge plate thickness to thick points ★ problem belongs to the subject: professional information technology engineering water conservancy project the above content is based on the actual work of the students encountered problems, for reference, if any questions please communicate in time, correction
Q:Power cable YJV22-8.7 / 15kv-3 * 300 what meaning
(Including the insulation layer) of the total area should not be greater than 40% of the internal cross-section; . the tube wire is not allowed to have joints and twist the phenomenon; . the same loop of the phase of the wire, Regardless of the number of roots should be penetrated into a tube, and different circuits and different voltage lines are not allowed to wear a tube, AC and DC line wires shall not wear a tube, a phase line are not allowed to penetrate alone Steel Pipe. If the requirements are not strict, the power cable, the control cable can wear the same tube; but the signal line will be discretionary, although the signal line is shielded cable, but in order to maximize the signal transmission quality, and other signal lines are generally layout. UPVC plastic pipe with excellent insulation, acid, corrosion resistance, many chemical plants used as infusion piping. The other is also used for sinking engineering, medicine piping works, mineral salt water piping works, electrical piping works. Also widely used as a telecommunications cable. So it can be UPVC pipe to do electrical piping. As for the galvanized steel pipe is not necessary. If the power cable and signal cable at the same time with UPVC pipe laying, were classified separately perforated, the best interval between the two 20cm to prevent interference, with galvanized steel pipe pipe is not necessary so care.
