kvv and kvvp inside the line used for a single strand of thick copper wire composed of hard wire, i.e. bv wire composition.
avvr and rvvp difference: the same thing, just the internal cross-section of less than 0.75 square millimeters of the name for avvr is greater than or equal to the name of 0.75 square millimeters of the name for the rvvp.
syv and sywv difference: syv is a polyethylene insulation of the video transmission line. sywv is a radio frequency transmission line, the physical foam insulation. Used for cable television.
rvs and rvv2 core difference: rvs is a two-core rv wire stranded, no outer jacket, used for broadcasting connections.
rvv2 core wire straight put into cable, there is an outer sheath, used for power, control signals, etc.
