CMA = D2

CMA = d x N

N = Number of Strands

STRIPPING WIRE; GOOD STRIPS

Square, even cut

No nicks or cut strands

P1767 19

STRIPPING WIRE; BAD STRIPS

Nicked Strand

Cut Strands

Cut at Angle

Tapered or Torn Insulation

P1767 20

Results of Bad Strips = Loss of Electrical Characteristics

Nicked and cut strands =

Decreased electrical and

mechanical strength

Uneven or tapered strip =

Insulation in wire crimp

Incorrect

-Correct stripping

-Insulation correctly

positioned into the insulator

support

Insulation stripping to long

Insulation stripping to short

and crimping on the

insulation

Conductor stripping too short

Strands crimped with the

insulator support

One or more strands of the

conductor not crimped

Correct

Incorrect

-Strands apparent in the

inspection hole

-The insulation penetrates

correctly into the cup

Insulation stripping too

short, conductor not visible

through the inspection hole

Insulation stripping too

long, the insulation does

not penetrate into the cup
