Q:What is the difference between VV22 and VV62?
Cable flow current is to be hot, look at the table with a look at the current is normal, the current is consistent with the cable configuration. Laying the environment is normal.
Q:150,120,95,50,25,10,4 * 1.5,2 * 1.5 how much cable to use the heat shrink tube
Due to the circumstances of the question .. at any time questioned us
Q:What is the difference between a pre-branch cable and a punched clip?
Cable bridge is used to support and protect a variety of cables, in power plants, substations, large industrial and mining enterprises, high-rise buildings are widely used. But are a one-time infrastructure in place, usually no longer replace and add.
Q:"Cable laying" cable cross-sectional area refers to the cable cross-sectional area, or refers to the copper core cross-sectional area
Low-voltage power cable, also known as: low-voltage power cable. The voltage rating is 0.6 / 1KV. National Standard No .: GB / T-2008. The voltage rating of the control cable is 450 / 750V. National Standard No .: GB / T9330-2008. The voltage rating of these two cables, the country has a clear standard. Can not be changed.
Q:Apple mobile phone does not support this charge when charging this thing how to charge
Can not! "Power Cable Design Code" Article 5.1.3 provides that the number of stents by the channel space constraints, 35kV and about the adjacent voltage level of power cables, can be arranged in the same layer of stent. 10kV power cable (actually 8.7 / 10kV) and 380V power cable (actually 0.6 / 1kV) in the interval between the 6kV and 3KV two voltage levels, not the adjacent voltage level, can not!
Q:Cable zc_y v22 what does it mean
If you put seven 1.0 square conductor twisted together, as a power can of course. But you twisted the copper wire, how to solve the insulation? In addition, the manual twist, then there is the problem of density, can not be a bit twisted copper wire twisted round? And if you put the seven core core is not peeling, directly twisted together, then, when the wire when the core heat how you solve. So, do not use this line to do home improvement. But if you want to use this line to do the lamp line or can.
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 recycled rubber is suitable for the production of wire and cable?
The power industry mainly includes electricity industry and power plants and other power cables industry is the power industry to do the cable and cable should belong to the power industry but does not belong to the system within the power system only includes the State Grid China Southern Power Grid five nuclear power plants and other large state-owned enterprises
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 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.
