To be soft is to increase the number of conductors BV copper conductor PVC insulated wire BLV aluminium core PVC insulated wire BVR copper conductor PVC insulated flexible wire Above wire structure: conductor + insulation Take 2.5mm2 for example: BV is 1 in diameter, 1.78mm in 7, and 0.68 in two BLV is the 1 diameter 1.78mm BVR is the 19 diameter 0.41mm RV copper core PVC insulated flexible wire Is it softer than BVR, or 2.5 is the 49 0.25mm copper wire? RVV copper core PVC insulated PVC sheathed flexible wire More than RV a layer of plastic sheath In addition: our most commonly used "sheath line"" BVVB copper conductor PVC insulated and sheathed flat cable It's 2 BV lines, plus a white sheath on the top Give you valuable information I collected electrical design, construction drawings are commonly used line laying method: SR: laying along the steel groove BE: laying along the roof truss or roof truss CLE: laying along columns or columns WE: laying along the wall CE: laying along the ceiling or ceiling ACE: laying in the access ceiling BC: buried in the beam CLC: buried in the column Ws: buried in the wall CC: concealed in the ceiling ACC: concealed in the ceiling that is not accessible FC: buried in the ground SCE: the ceiling should be laid with metal pipe First, the conductor through the tube that SC- welded steel pipe MT- wire tube PC-PVC plastic hard tube FPC- flame retardant plastic hard tube CT- Bridge MR- metal wire groove M- cable CP- metal hose PR- plastic wire groove RC- galvanized steel pipe Two.
