| Conductor |
Bright annealed bare copper
of high electrolytic grade drawn to fine strands, multi
strands bunched together rope shaped wire for uniformity
of conductor dia, resistance, dimensions and flexibility
etc. The diameter of the conductor is so uniform that
strands do not get cut when stripping the insulation thus
conductor gives perfect conductivity which eliminates
spot heating and sparking. |
| Insulation |
Specially formulated grade of Halogen
Free Flame Retardant compound is used. The performance
of the Cable in fire situation is exceptionally good.
The insulation does not melt, drip or spread the fire
conditions. The smoke is negligible, transparent and non-toxic. |
| Marking |
The Cable are printed with generic
marking ELKAY - ZHFR |
