Building Wires are general cables for electrical purposes. These cables are selectively used for general wiring and are further classified into FR, FRLS and HRFR. FR stands for Fire Retardant, FRLS Fire Retardant Low Smoke and HRFR HEAT RESISTANT FLAME RETARDANT wires. As the name suggests they are meant to stay away from any burn down, caused due to short circuit or any other accidental reasons. These wires are meant to safeguard you and your appliances life by terminating and resisting any fire-spread caused due to electrical mishap. These are most preferred wires conventionally demanded everywhere.
