Wire, copper wire, why some copper wire can be easily twisted together, and some twisted together and bounced back to the original state?
Generally speaking, what material is not doped, but copper impure.RVV is a copper core PVC insulated PVC sheathed flexible cable, soft sheath wire, a sheath wire.Rubber lines are seldom used for civilian use.
You don't agree by default. Model letters are subject to national standards and are not optional. Such as BV, BVR, ZR-YJV, NH-YJV, and so on. RX is a rubber insulated wire and is now seldom used.
Of course, it is very easy, can be twisted together well, pure copper is very soft, and that twisted together and bounced back to restore the status quo, is a genuine shoddy products.
