Special Insulation Wires
- Flame Retardant Low Smoke (FRLS) wire: These wire are made of special insulation material with higher oxygen and temperature indices and lower smoke density rating and acid gas generation. This insulation retards flame propagation in buildings and industries. This insulation generates low smokes under fire condition.
- Zero Halogen Flame Retardant (ZHFR) wire: The insulation is free from halogen, thus preventing emission of corrosive gases under conditions of fire. These wires are primarily used where critical control supply is essential during a fire-lifts, fire alarms, hospitals etc.
- Oxygen Index is use as a measure of flame retardant property of the insulating material. The oxygen index indicates percentage of oxygen required for supporting combustion of insulating material at room temperature. The ordinary PVC insulation has an Oxygen Index of 23% Higher Oxygen Index is desirable.
- Temperature Index indicates the temperature at which normal oxygen content of 21% in air will support combustion of insulating material. Higher temperature index is better.
- Smoke Density indicates the loss of light transmission from insulation material under fire. Lower the smoke density, the better is the visibility & efficacy of fire fighting operations.
- Acid Gas Generation indicates the amount of hydrochloric acid gas evolved from insulation of cable under fire. Lower Acid Gas Generation is desirable.
