wire: consisting of one or more flexible wires,
wrapped with soft sheath;
cable: consisting of one or more insulated wire,
a tough outer covering of metal or rubber.
cables and wires are generally made of wire,
the three components of insulation and protective cover.
common cable characteristics are as follows:
cef - ethylene propylene rubber insulated chloroprene rubber sheath.
cvv - pvc insulated, pvc sheathed flame retardant power cable for ships.
oxygen wire used by bv, bx, rv, rvv series wire,
which:
bv: copper core pvc insulated wire,
long term allowable temperature 65 deg c, minimum temperature -15 c,
working voltage ac 500v, dc 1000v,
the utility model is fixedly arranged on the interior and exterior, and can be used for light deposition or light application.
bx: copper core rubber insulated wire
the maximum operating temperature is 65 degrees centigrade. .
rv: pvc insulated single core cord,
the highest use temperature of 65 degrees, the lowest temperature of -15 c,
working voltage ac 250v, dc 500v,
internal wiring for instruments and equipment.
rvv: copper conductor pvc insulated and sheathed flexible wire,
allow long working temperature 105 deg c,
working voltage ac 500v, dc 1000v,
for wet, high mechanical protection requirements,
often moving and bending occasions.
