Is there a difference between PE cable and PE water supply pipe?
The above wire structure: conductor + insulation Take 25mm2 as an example: BV is a diameter of 178mm and seven 068 two; BLV is a diameter of 178mmBVR is 19 diameter 041mm; RV copper core PVC insulated soft wire it is more soft than BVR, Or 25 is 49 025mm copper wire; RVV copper core PVC insulated PVC jacket to connect the soft wire than the RV a layer of plastic jacket Another: our most commonly used "jacket line" BVVB copper core poly Ethylene insulated PVC sheathed flat cable is two BV lines, plus a layer of white jacket
BVR, RV, RVV, not those of the large cross-section of the project with the cable B series classified as cloth wire, so the beginning with B, voltage: 300 / 500V; V is PVC PVC, Is the (plastic); L is the aluminum core code; R is (soft) means, to be soft, is to increase the number of conductors; BV copper core PVC insulated wire; BLV aluminum core PVC insulated wire; BVR copper core PVC insulated flexible wire
BV, BVV, BVVB, BVR Power cord: simple: vv in the wire term refers to the two layers of vinyl meaning; BV exposed ethylene insulated copper wire, single core wire; BVV, exposed vinyl sheathed copper core Wire, two core wire; BVVB exposed vinyl sheathed copper wire, is the three-core line; BVR, copper core PVC insulated flexible wire, fixed wiring requires soft occasions
