Just touch the cable industry, how can we quickly remember the cable product model and name and the like

Answer:

. not the medium voltage power cable marked "8.7 / 10kV and 8.7 / 15kV", but depends on the manufacturer is 10kV insulation requirements for production, or by 15kV insulation production; this is not a thing of the two . the power cable nominal 6 / 10kV, refers to the cable can be used in the phase voltage of 6kV, line voltage of 10kV system, which is the so-called 10kV system in the normal cable; but in many cases , Phase, line voltage may be increased, such as 10kV system is a neutral point is not grounded system, when the single phase ground will cause phase voltage increases, then 6 / 10kV cable can not be used to increase the phase insulation; If the capacitor increases the reactor, the line voltage will rise more than 10kV rating, so then the 6 / 10kV cable is not enough, so only to increase the insulation layer, to increase the line insulation; this has 8.7 / 10kV and 8.7 / 15kV power cable; . in this talk, many people in the procurement of cables, only that their procurement of 10kV cable, and no specific technical requirements, to some manufacturers caused by the opportunity, many manufacturers to reduce insulation, Reduce the diameter, reduce In addition, to select enough to produce qualified, good reputation of large enterprises, although the price may be more expensive, but the quality of protection, I have been to some small manufacturers, you have to pay attention to the safety of the user, And he said two kinds of cable, he only know that 10kV cable, simply can not tell the difference between the two, but dare to give you the manufacture of cables, make products that you play what signs, this product you choose to rest assured? If not other considerations, or do not use some of the poor quality of the product as well.
I think this issue is not clear provisions, the general red is FireWire, but not absolute, so still try to test with a pen as well, please refer to.
