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:The computer host is always start to stop, resulting in the last can not start. What is going on?
Do not worry, no problem, the power cord can withstand the general high temperature, not recommended to use extension cord, the more joints more easily lead to some inexplicable problems.
Q:Cable yjv-0.6 / 1kv-4 * 120 + 1 * 70 What does it mean?
There is no difference between BTTZ25 square can only do single core. BTTZ is a kind of outer layer with seamless copper tube jacket, the middle filled with magnesia crystal powder as insulation material, the conductor is a single strand of copper rods composed of new cables, in recent years are also more used in high-rise buildings, airports, Underground railways and other places, to protect the fire in the case of fire pumps, fire elevators, local lighting, emergency evacuation instructions, security monitoring, anti-smoke system and self-powered power and other important equipment uninterrupted operation. The main features of the editor it has a high temperature, fire, explosion, no combustion (250 ℃ can be a long time running, 1000 ℃ limit state can also be 30min short time operation) and the current flow, small diameter, high mechanical strength , Long service life, generally do not need the characteristics of independent grounding wire. Application range Editor Widely used in nuclear power plants, metallurgy, chemical industry, mine, kiln and other dangerous, bad, high temperature environment. In recent years, more applications in high-rise buildings, airports, docks, subway and other places, to protect the fire in the case of fire pumps, fire elevators, local lighting, emergency evacuation instructions, security surveillance, anti-smoke system and self Power and other fire fighting and important equipment without interruption.
Q:Will the two 16 square copper wire with what specifications of the trunking
If the network cable is shielded with the network no problem, in fact, the main problem is not interference, it touches on security issues, from the truth, the strong and weak electricity can not take a bridge, if you must go inside a bridge, to add metal partitions The
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: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
Man, your weak tube is not quite long? If the length of the pipeline is very long, you need to wear the wire, unless you have no wire can be threading method. Your length of the pipeline is very long, in the tube when the tube has been added? There is no wire box to make up.
Q:Computer host configuration of about 1,000 yuan (preferably 1000 below) - probably as follows;
"Electrical design of civil buildings," 8.10.13; steel cable bridge straight section length of more than 30m, aluminum or glass fiber reinforced plastic cable bridge length of more than 15m, should be set up expansion joints. Cable bridge across the building deformation joints, should be set compensation device. The telescopic section is set for temperature change; the compensating device is to prevent settlement at the deformation.
Q:Water and electricity installation drawings in the kz on behalf of what material of the threading tube
HDMI interface common in some new TV, which is called "digital high-definition multimedia interface", mainly for the transmission of high-quality, lossless digital audio and video signals to high-definition television, the maximum bandwidth of 5Gbps In addition, There is also an interface you need attention, this interface is called "DisplayPort", it can provide the same function with the HDMI interface, and can provide bandwidth up to 108Gb / s, much higher than the HDMI interface More importantly, DisplayPort is free Standard (HDMI charges), almost all of the personal computer manufacturers and graphics card manufacturers have expressed support for this interface
Q:What is the power cable accessories used to do?
When using power, standby power, basically no radiation, can be considered negligible
