What does the control cable 6 * 0.75 + 1 mean? There is no back +. do not understand what this means? Hope professional answer! The The Question added: that the price is the two add up to it? More
In the Chinese specifications should not be 8 level, but the wire according to the cross-sectional area and environmental factors the same cross-sectional area conduction current is not the same.
Copper core: 1.5 square can carry 24A current, 2.5 is 32A, 4.0 is 42A; aluminum core: 1.5 is 18A, 2.5 is 25A, 4.0 is 32A. Power (watts) = voltage * current, their own calculation. Port algorithm: 10 square below the current multiplied by five, copper line up, pipe high temperature 8/9 fold 2.5 square high level is 4 square, 4 times 5 equal to 20 amps if the tube is then multiplied by 0.8 ambient high temperature multiplied by 0.9 both through the tube and the high temperature multiplied by 0.722.5 square copper The manual carrying current in the manual is 27 amps. If it is 220v indoor voltage, is probably 6 kilowatts
The front has been said, the essence is the insulating form of different YJV cable is cross-linked polyethylene insulated PVC sheathed power cable, generally used for power KVV cable is PVC insulated PVC sheathed control cable, generally Used for control. They are insulated, one with cross-linked polyethylene, one with polyvinyl chloride. In addition, the core will be different, because YJV are dynamic, core thicker, some very thick, . 400 are, but the core number is less, generally no more than . KVV core thin , I have not seen more than 2.5 KVV lines. And the number of cores can be a lot, dozens of have
Now people are TMD Diao, GB only 5 core and 7 core control cable, some people choose what 6 core, and make production and offer no standard, you said the 6 +1 core I have not seen. You say the price together, there is no such argument, if it is a separate 6-core cable, the weight of its jacket is certain, if coupled with a . the jacket will increase the weight, the price is not two Add so simple. For example, the power cable 3 + 1 core price is not 3-core price and 1-core price of the sum, because the 3 + 1 core has its own structure, structure is different, not used materials, the price is different. I was doing cable quote I believe hey wufang. I would like to ask GB9330-88 on the 6 core?
