Heat Resistance Fire Retardant (HRFR):
Fire is one of the most dangerous element’s which results in
adverse loss of money and resources. There have been many
fire-accidents in the past due to the corrosive fumes and
flickering fire of the cables. Electrical engineers involved in
generation, transmission and utilization of electricity, observed
the behavior of ordinary cables in highly flammable
environment and identified the need to create cables that are
immune to fire. Usually, all XLPE cables are layered with a
protective covering of Polyvinyl Chloride also known as PVC.
Although, PVC is immune to flames due to its flame retarding
property. With the contact of fire, it does produce highly toxic
fumes which are corrosive in nature.
The supply of electricity is essential in every domestic and
business environment. However, in many crowded and packed
places like power stations, subways, railways with long
sections in tunnels, road tunnels, ships, hospitals, schools,
hotels, cinema theaters, museums and public premises,
electricity- fire breakouts are subjected to spread at a faster
pace destructing life and property. Although, the XLPE cables
come as a rescue, the highly toxic fumes emerging from them
during fire accidents cloud and clog surroundings rendering
them invisible to victims. The toxic fumes and opacity
emerging from these cables elevates the risk of suffocation
and pose a threat to human safety.
Heat Resistance Fire Retardant PVC compound ensures low
smoke emission compared to ordinary wires with PVC
coating. They are less toxic in nature and emit considerably
low amount of corrosive fumes. In short, they perform tasks
as fire retardants.
