What is the difference between the BVV line and the BV line?
RVV - Copper core PVC insulated PVC sheathed cord. RVS - Copper core PVC insulated stranded cord. KVV - Copper core PE insulated PVC sheathed control cable. RVVP - Copper core PVC insulated PVC sheathed shielded cord.
Will load 473KW current 560A need much cable, how big the casing
BV, BVV, BVR power cord: simple tick: vv in the wire term refers to the two layers of the meaning of the release of ethylene; BV exposed ethylene insulated copper wire, the core line; BVV, exposed vinyl sheathed copper wire, BV, BV, BVV, BVR, copper core PVC insulated flexible wire, fixed wiring requires a soft place to ask people to ask the usual wire on the market BV, BVR , RV, RVV, not those large cross-section engineering with the cable B series classified as cloth wire, so the beginning with B, voltage: 300 / 500VV is PVC PVC, that is (plastic), L is the aluminum core code R Is the (soft) beard meaning, 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 above wire structure: conductor + insulation take a V 2.5mm2 PVC insulated flexible wire connection is softer than he BVR, or 0.25mm copper wire 49 is 2.5 RVV PVC insulated PVC sheathed flexible wire connection more than one RV plastic sheath Also: our most common tick "jacket line" BVVB copper PVC must PVC sheathed flat cable 2 is BV line, plus a layer of white tick sheath.
Try not to go together. The ups line is a backup power supply. Is considered in the emergency inside
