The difference between the power cable YJY22 and YJY23 is in the outermost layer, one for the PE sheathed, one for the PVC sheathed. What is the applicable environment, and why? Question added: I have to ask is the difference between 22 and . not 22 and 32! Thank you for the answer. Learn more together
The bearing capacity of the square millimeter in the wire decreases with the increase of the wire diameter, for example, 1 mm square meter
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
35 square copper wire current carrying capacity is 105A, 105A / 35 mm2 = 3A, (1 square millimeter carrying capacity is 3A) 70 square copper wire current carrying capacity is 169A, 169A / 70 square millimeters = 24A (1 square millimeter carrying capacity is 24A) 1 square hai load current from 11A gradually become 24A So it is impossible to use n by the coefficient can be drawn to the current value Wire can carry the current * the applied voltage * power factor = can drive power The diameter of the wire with different diameter is not the same No specific diameter can not know the current carrying capacity How much power, depending on the voltage level Because P = UI As the saying goes: a square 4 current, underground than this small forget How much is the square here is a square millimeter Power depends on your voltage, the general small line can be directly by 5 is to eat the current to 50-120 the basic can take more than 35 can take 25 or so just personal experience to do reference to the need for basic data: 1 line, copper and iron Aluminum silver temperature 3 core number 4 diameter Probably take a square 5A diameter n square of the wire can be over n high current, resulting in n high power so that can be calculated
