Product Description:

The cable longs run , the highest working temperature can't exceed 70 , does not exceed 160 while holding up in 5 seconds, The cable is not limited by the drop when being laid, environmental temperature is not lower than 0 when laying. Minimum crooked radius of the cable while laying: It is in single core cables 20( D + d), mm, multicore cable( D + d), because mm,( d respectively from cable and actual external diameter of conductor in D of 15, If the leading body is not a round, then d =1.13 √S.S take as the leading factor body marked and claims the section, unit mm2)

 

Lay and require insulating and regularly with the performance of the electric wire:
1 Allow working temperature for a long time:
BV-90, RV-90 type are at the time of using normally, high temperature the most of conductor is 90
. Use as right to use of the cable environment can prevent from hot to mould and flow and permit and reduce insulating situation of resistance, The PVC mixture that can be used in 90 in succession , base on the premise of always shorten working timing, Its working temperature can be improved to 105 . Other types should not exceed 70
(2)The temperature of laying of the electric wire is not lower than O , allow the crooked radius: The person who smallers than 25mm should not be smaller than 4D for the external diameter of the electric wire( D), the external diameter of the electric wire( D) is not smaller than 6D for 25mm and the above person.

Q:What is the difference between a shielded cable and a control cable?
You and he said that he did not understand the professional. Indoor use KGB, JDG steel pipe or PVC pipe outside the road with steel, non-road can use PE pipe
Q:110 voice patch panel directly to the telephone line can be connected to it
See home improvement or tooling, home improvement we will be buried in the trench below the pipe. Also need not particularly out of the picture, not so high demand. All the lines of the tooling must take the bridge, that is, from the ceiling to go, must be strong and weak to separate a distance, the line can not exceed 40% of the tube (tooling home improvement) to no longer clear the label is not OK, simply can not repair. And this is the national norm. Of course, the construction process of a lot of strong power or take the ground, but this is inside the floor. Can be drawn directly.
Q:With a i3-2100 desktop computer about how much money. To have a separate graphics card. Give a configuration alone, no more than 4000
The length of the cable bracket is determined by how much the cable is
Q:The difference between power cable and overhead cable
. the power cable occupies less. Generally buried in the soil or laying in the room, the channel, the tunnel, the line between the insulation distance is small, no tower, covers an area, basically does not occupy the ground space. The overhead cable is the opposite. . power cable reliability. Affected by climatic conditions and the surrounding environment, transmission performance is stable, high reliability. . the power cable has to ultra-high pressure, large capacity development of more favorable conditions, such as low temperature, superconducting power cables. . the power cable distribution capacitor larger. Overhead cable is the opposite . the power cable maintenance work less overhead cable is the opposite . the power cable electric shock is unlikely. The overhead cable is the opposite
Q:What type of cable is the power cable?
Now you have seen what products are not 3c certified? But most of them are fake. Messy on it. Who will check this?
Q:The difference between the instrument cable and the low voltage power cable
Meaning the cross-sectional area of the wire, the unit is square mm; for example: 4 square copper wire, the cross-sectional area of the wire is 4 square millimeters, copper wire;
Q:What is the fire wire pipe laying? What is the galvanized steel pipe?
Inverter special cable General power cable difference shielding requirements higher, the number of cores is generally 3 +. three lines of the ground line of three symmetrical and phase line intersection. Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
Q:Calculation method of wire and cable outer diameter
(In accordance with the power cable, single-core cable sheath of the nominal thickness should not be less than 1.4mm, multi-core cable nominal thickness should be not less than 1.8mm), the thickness of the jacket, 2. On-line measuring sheath thickness: Sheath thickness = (circumference after extrusion of the jacket - circumference of the jacket) / 2π or sheath thickness = (circumference after extrusion of the jacket - before the jacket Circumference) × 0 .. Insulation thickness of the most thin point: Nominal value × 90% -0.14. Single core sheath the most thin point: Nominal value × 85% -0.15. Multi-core sheath thinnest point: Nominal value × 80% -0.26. Wire armor: Number of roots = {π × (inner sheath outer diameter + wire diameter)} ÷ (wire diameter × λ)
Q:What is the warranty period for wire and cable?
The state is 30 years warranty. But the specific warranty period according to the type of wire and cable and the use of conditions and temperature and applicable methods to determine.
Q:Wire inside the two lines, red and black, black line is the line of fire or zero line ah?
According to the size of the product to open a good plastic mold and then purchase the plastic raw materials to be injected (raw materials depending on your product requirements, advanced point will use To the engineering plastics PE, PS, etc, and even to join the flame retardant, fiber material), the difference is like now with the charger on the use of only PVC3 Called the wire manufacturers according to your request to do a good line Of course, you have the conditions you can pull the wire of their own beer process: mold on the machine (ingredients test mode) --- welding wire and hardware (pin) --- then put the welding hardware on the mold (according to the mold Put five to ten range) - boot molding - detection of another: If you want to have all the country's certification, it is estimated that you no technology is not too, you can not buy that hundreds of thousands of equipment to detect The power line in the material composition and a variety of techniques to wear flattened Fenbao match platinum standard, because the formal power It is too much to be recognized, but you want to do ordinary DC line, such as mobile phone charger or no problem, but the regular factory what automation machine to do, then I do not know, but it is automated machine estimates But also the cost of scary Anyway, ordinary manufacturers do have any questions can EMAIL: qingxinghe@21cncom Do not call me in Google, I rarely said so much, add points to me, huh, huh
