Polycab FR Wires:
In case of Polycab Wires Mica tape is wound on the copper conductor before an insulation of Zero Halogen Flame Retardant is extruded on it to give the required function of supporting fire fighting. The details of construction of such wires is as follows,

Conductor:
Multi-strand copper conductors which are accurately drawn in imported Fine Wire Drawing Machines and annealed on-line are uniform in resistance, softness and brightness. These conductors are then bunched on synchronous motor driven takeup drive to ensure zero tension on the conductor thus ensuring uniform resistance. Further compacting of the bunched conductors enables reduction in the overall diameter, thus improving the wiring density in the conduits.

Protective Layer:
Two mica tapes are wound spirally to cover the complete length of the conductor to sustain temperatures of 750°C and 1100°C to ensure at least 1 hrs and 3 hrs respectively of smooth passage of current in the wire before disruption

Insulation:
Cross Linkable Low Smoke Zero Halogen (LSOH) compound is used to outperform all other insulations on toxicity front by generating near zero toxic gases in case of fire. The smoke generated is whitish and of density as low as 20%. Low human casualties are ensured due to low, whitish and toxic free nature of smoke. Indeed POLYCAB FS wires, the premium eco-friendly wire, fights fire on its own and thus helps save human lives much before complete damage takes place due to fire.

These 3 wavelengths result from the attenuation characteristics of glass as well as from the availability of semiconductor type sources and receivers. They are referred to as the three wavelength windows in fiber.
