- Q:Yjv22 cable laying pipe when the casing with plastic or steel pipe
- (4 × 185 + 1 × 95) is the cable specifications, indicating that the cable has 5 cores, of which 4 cores are 185 Square millimeters, one core is 95 square millimeters. General 185 line is the main core, power with, 95 for the ground core, ground use.
- 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:Whether high voltage cables can be built in belt corridors
- When the short circuit occurs when the wire through a large current, more than the rated current of the wire, so the wire will heat
- Q:PVC pipe on the GV.215-16 (C) What does it mean
- TC line laying is the use of wire steel pipe laying. Wire steel pipe is a thin-walled tube, the nominal diameter is the outer diameter of the pipe. SC line laying is the use of ordinary welded steel pipe laying. Ordinary welded steel pipe is thick-walled tube, nominal diameter is tube diameter.
- 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:The UV lamp is fitted with ozone and no ozone difference
- . like the computer boot fast, the best way is solid state hard drive, followed by the win. the system is very good, the interface is also familiar with the boot fast, especially the new browser edge than a lot stronger; . if you now computer The monitor is also good, and now the computer's hard drive can be taken down to the new computer above, then 3000 yuan can buy very very good, desktop. If the notebook is about 4500 or so relatively high cost. . do not recommend the configuration of their own one by one to buy accessories, it is recommended that you look at the top of the machine installed Taobao business, they rely on the volume, not only to ensure that the genuine accessories, the price is relatively cheaper to buy their own, And wiring installation are also professional. And they are equipped with win7 is free to upgrade to win. very good. I just bought a few days ago a machine, monitor and hard drive or use their original, with the host with the solid-state hard drive as a boot disk, their hard drive as a storage disk, spent a total of . the performance is very good.
- 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:Wire and cable manufacturing process (to be detailed)?
- Copper core per square of the safe current (continuous use) for the 2.5A, intermittent use of 4A, according to the power count 550W-880W.
- Q:Can 110kv and 10kv cables co-share with trenches? What is the relevant specification?
- With a straight pipe with a matching pipe (commonly known as the hoop), in order to prevent the joints at the slippery, PVC glue can be used after the smear. If the trouble, then use the electrical cloth cloth to the two tube package can also be strict.
- Q:Emergency power off after the computer can not open the machine, an open is a lot of words appear seconds limit, you can
- Buried a few is based on the project to be set, as to how much diameter will be based on your plan to determine the cable, the national standard to protect the tube diameter at least 1.5 times the diameter of the cable through the cable. Embedded is to consider the size of long-term power supply, when the load increases, you can directly in the embedded casing to wear cables, so that one-time embedded well, not to re-dig cable cable buried cable, saving time and effort, but also to avoid the Damage to the original cable foundation and the road above the cable
