Test Certificate -

We provide test certificate detailing test results obtained in our factory with every drum that we dispatch.

Bending Radius -

While installation of PVC insulated heavy duty cables of 650/1100 volts grade, bending radius should no be less than the following -

I. Single Core Cables - 15 times the overall diameter of Cables.

II.Multi Core Cables - 12 times the overall diameter of Cables.

Current Ratings

The continous current ratings and the rating factors for PVC insulated Heavy Duty Cables, given here are generally in accordance with IS: 3961(Pt.II)1967.

Basic Assumptions

The current ratings are based on the following installation conditions -

I. Maximum conductor temparature 70° C.

II. Thermal resistivity of soil 150° C cm/w.

III. Thermal resistivity of PVC 650° C cm/w.

IV. Ground Temparature 30° C.

V. Ambient air temparature 40° C.

VI. Depth of laying (to the highest point) of cable laid direct in the ground 75 cm.

Short Circuit Current Rating of Aluminium for 1 Second Duration.



Short Circuit Ratings of Starcab Cables can be calculated by using the following formula 
       lsh = KA / sqrt ( t ) 
where 
   lsh - Short circuit current im amps.
   A - Conductor area in sq. mm.
   t - duration of short circuit in second.
   K - 75.80 for Aluminium Cables.
   K - 109.00 for Copper Cables.
