Q:How to identify the quality of the lock of the hotel lock?
Ming assembly line tube card 1 meter a, turn from the wall 10 a square, far away, the tube will fall down.
Q:What is the difference between VV22 and VV62?
The conductor of the cable is resistive, and the current when the cable is running through the conductor to heat up. In a certain installation, ambient temperature conditions, the heat generated by the conductor current and cable in the operating environment under the conditions of the heat dissipation is equal, when the current is safe operating current, which is commonly referred to as the cable carrying capacity. Cable carrying capacity is in a certain installation, ambient temperature conditions, the load, so the installation, the ambient temperature conditions are different, carrying capacity is different from the ambient temperature changes, the safe current is also to change. Therefore, if the cable is running at a certain installation and ambient temperature, if the actual carrying capacity of the cable exceeds the safe cut-off, the heat generated by the conductor is greater than the heat of the distribution, the cable will heat up; the same time when the ambient temperature increases The ability to heat down, if the current carrying capacity is not reduced, the cable is to heat.
Q:What does ZR-YJV 6mm2 * 3 cable mean?
4S shop is a single-brand car franchise model with "four in one" as the core, including vehicle sales (SALE), spare parts (SPAREPART), after-sales service (SERVICE), information feedback (SURVEY)

Q:Apple mobile phone does not support this charge when charging this thing how to charge
So, from the degree of hearing up, it is not suitable for the family pet
Q:PVC pipe line 6 points and 4 points which big ah?
Look at the chassis of the internal power supply is not connected to your power interface to see how many mouth ~ there is a 4-port square of the additional power socket to see there is no link that is what the link method is generally written on the motherboard ~ The word is a small look carefully ~ Corresponding to the chassis of the various plugs to see if there is no wrong plug (but the general can not start too much Gibel error) can be observed by the power indicator light (light) and observe the hard disk indicator Red (flashing) to determine the right or wrong line. There is only listen to the warning sound, the boot will be crisp ring, if there is proof of plug, there is no relationship in fact because there is no alarm, hdd hard drive, led + - white green two-wire power instructions, the above said three lines Do not plug can also be a normal boot, as long as it pw power plug can be a ~ rw restart does not affect the boot
Q:Fourth, what causes the power cable fire accident
Once the cable in the event of fire, the fire ferocious, rapid spread, in the burning will occur when a large number of harmful gases, resulting in fighting difficulties
Q:How high voltage armored power cable is grounded
Copper braided wire for cable and shielding lead wire. Stripped of the core of the copper shield with the outer layer of the plastic belt, the shield copper belt polished smooth, with electric iron, solder braided copper braid were welded in the three core copper shield tape. And then use the emery cloth polished armored steel strip welding area, with a soft copper wire and copper shield belt tied with three armored steel, and then use electric iron, solder braided copper braided with armored steel belt. In the sealed ground to fill the braided wire with solder to form a moisture-proof section.
Q:Water and electricity installation drawings in the kz on behalf of what material of the threading tube
No, without this provision, the purpose of blocking the cable piercing is to prevent the outside world on the adverse gas and other reasons of the invasion, in fact, as long as the purpose is achieved, the material selected or look at the situation, such as coal mine perforation must be sealed , The reason is to prevent the wind and air leakage, as well as when the outside world when the explosion of the substation damage, as well as their own substation has a fire source to prevent the development of fire to the outside world
