Multi-strand conductor is stranded conductor. i.e solid area
is divided into no. of small area's( 1 sqmm wire is having
14 strands of 0.3 mm dia. which gives equivalent area for 1
sqmm solid conductor). By stranding the conductor, total
circumference will increase as compare to single solid
strand. further, 0.45mm should be dia of single strand and
370 would be the no's of strand in the cable.
