If 95 sqmm is the area of the cable I am sure you can calculate the diameter.

Why don't you use a Veiner caliber to check the diameter of your cable. See ... it so simple.

you can use the formula ( Area = .7854×d² )

I think I might have to change it. Thanks.

The cable area refers to the conductive area and will depend on the type of cable, number and size of strands, and if the strands are circular, or if it is a compressed style of cable. Best way is to go to the cable manufacturers specifictaions and look it up. Most do have web sites.

Diameter = 11 mm

A=pi(d squared)/4, 95=pi(d squared)/4,d=SQRT of 380/pi or d=SQRT of 120.957

d= 10.998 or 11mm

Out of the book for one manufacturer:

95mm² Compacted Cu PVC Insulated, 0.6/1kV V90 - nom overall is 15.2mm with nom insulation of 1.6mm thickness

95mm² Compacted Cu SDI as above - nom dia 18.2mm.

Need more details on the cable, 95mm² marking on the cable does not provide enough info on if it is a 4 core and earth, 3 core and earth, SDI (Single Double Insulated). Could even be some of that quad style aluminium solid cable that can be found at odd times.

Trevor.

-if this cable is stranded (i.e 7 wire)

overall diam.= 3*wire diam.

-if this cable flexible

overall diam= 1.16*wire diam*√no wires

Felix, I assume this is an electrical cable? I the US we use the circular mil sizing system. If this is what you are interested in, this may help. One inch is equal to 1000 mils. So a cable that this 1/4 inch in diameter is 250 mils x 250 mils = 62,500 circular mils which makes is fall between a #3 and a #2 AWG (American Wire Gauge). I think the size you have listed falls between 3/0 and 4/0 AWG. Striker
