Q:Is the power cable considered a fixed asset?
According to the total number of meters, such as where to where a total of how many kilometers (meters). Power system fixed assets asset management software - TU Teng fixed asset management software.
Q:Cable WDZ-YJFE2 (4X185 + 1X95) what does it mean
Shaft bracket spacing is not necessarily a certain, and the bridge to the thickness of the model.
Q:Power cable casing buried what are the requirements
2 direct laying cable way, should meet the following requirements: 1 cable should be laid in the trenches, and should be along the length of the cable on the next, next to the side of the shop with a thickness of not less than 100mm soft soil or sand 2 along the length of the cable should cover the width of not less than 50mm on both sides of the cable protection board, protective board should adopt concrete 3 urban cable buried in the laying, it is appropriate in the protection board laying eye-catching signs 4 in the suburbs or open areas, along the cable path of the line spacing of 100m, corner or joint parts, should be erected obvious signs or signs 5 when the use of cable through the corrugated pipe laying in the trenches, should be along the full length of the bellows casting thickness of not less than 100mm of concrete, the width should not be less than 50mm outside the tube, the cable can not armor 3 buried in the non-frozen soil area, the cable embedding depth should meet the following requirements: 1 cable to the basement of the basement structure, not less than 03m 2 cable skin to the ground depth, not less than 07m; when located in the carriageway or farmland, should be properly deepened, and should not be less than 10m 4 buried in the permafrost area, should be buried below the permafrost layer, when not buried can be buried in the soil drainage of dry frozen soil or backfill, but also take other measures to prevent damage to the cable The 5 Directly laying the cable, is strictly prohibited in the underground pipe is just above or below The minimum distance between cable and cable, pipe, road, structure, etc shall be in accordance with Table 535 Table 535 Permissible minimum distance between cable and cable, pipe, road, structure, etc (m)
Q:What is the cable for the YJV33 cable?
DDF (digitalDistributionFrame) digital patch panel DDF digital patch panel digital patch panel, also known as high-frequency patch panels, digital communications in the increasingly superior, it can make the digital communications equipment, digital data stream connection as a whole , From the rate of 2Mb / s ~ 155Mb / s signal input and output can be terminated in the DDF rack, which wiring, transfer line, transfer, expansion have brought great flexibility and convenience of double deoxidation (DideoxyFingerprints, ddF) 2
Q:Power cable yjv22-10kv-3 * 50 what it means
Yj is cross-linked polyethylene insulation, v PVC sheathed 22 is double steel tape armored, voltage 10KV, 50 square three-core copper cable
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:Paint trunking, galvanized trunking: that good? expensive? Their advantages and disadvantages?
6 points 1 inch equals 10 points 1 inch equals 3.3 cm 1 minute equals 0.33 mm
Q:Lighting wire, I do not know is it. The When to use BV1 * 2.5, when to use 2 * 2.5, when to use 3 * 2.5, when to use 4 * 2.5,
This is generally not very good replacement, and you ask is not very specific, the proposed problem is more clear, more convenient for you to answer.
Q:What is the difference between the control cable and the compensation cable?
The reason why the wire outside the casing, is to protect the wire insulation from external damage. And the wire laying in the cable tray. The bridge has been gas to the protection of the role, so no longer outside the casing
Q:What is the role of patch panels generally, why should the switch connected?
The middle do not have to deal with, but also buried directly, deep 70cm, sand cover brick. It is difficult to repair, but economical and economical land.
