ABOUT LF FR
LF FR stands for Lead Free Flame Retardant Insulation. Keeping in line with Microtek's policy of manufacturing products that are safe for the environment, Lead Free PVC insulation ensures that the cable does not contain any chemical that might be harmful to the environment. Flame Retardant property ensures that the oxygen index required for PVC to support combustion is elevated to 29, as a result of which the cable retards the flame from spreading.

COMMON FEATURE OF MICROTEK FLEXIABLE CABLES
- ENERGY EFFICIENT CABLES: Microtek Cables provide highest level of electricity conductivity at 101% copper conductivity, exceeding the parameter indicated by the international annealed copper standard (IACS). This ensures minimum loss throughout the length of the cable which translate to 2-3% saving on the electricity bill. It also provides additional protection against voltage fluctuations.
- LOW VOLTAGE DROP: Drop in voltage from point of supply to the end receiving point is called voltage drop. High voltage drop across conductor is undesirable as it reduce the supplied energy. Microtek wires and cables have adequate conductor diameter to ensure low voltage drop and higher efficiency while using an electrical equipment.
- SHORT-CIRCUIT PROTECTION: Fire caused due to short-circuit is the common electrical mishap. Short circuit can be caused by the host of reason such as faulty wiring, broken insulation due to inferior quality of insulation, circuit-overload, and defective plugs, switches, cords, receptacles etc. Microtek wires ensure superior insulation and conductor characteristics to prevent short-circuit due to wiring.
- HIGHER Di-ELECTERIC STRENGTH: Di-electric strength represents the magnitude of voltage endured by a test-piece of wire when a specified voltage is passed through it for a specified duration of time. Higher di-electric strength means better electrical characteristics. PVC compound used for manufacturing Microtek Cables offers high di-electric strength to prevent electric breakdown in PVC.
- HIGHER CONVECTION OF HEAT: Convection is the flow of heat from hot to cool region. Lubricants like wax are required to prevent PVC-melt from sticking to hot extruder surface, which ensures a good heat transfer within the wire resulting in higher convective heat dissipation capability.
- WATERPROOF AND UV RESISTANT: In many building, construction concrete may itself not be water-tight. Contact with water causes deterioration of the cable's electrical and mechanical properties. Exposure of cable polymer to UV radiation induces chemical processes that causes polymer damage like chalking, loss of impact or tensile strength and a host of other chemical changes. All this can greatly reduce the service life of the cable and expose people to electrical shocks. Microtek has developed a high-quality thermoplastic insulation compound made of single carbon-bond polymer chain. This makes Microtek cables impermeable to water, ultra violet (UV) radiation and chemicals, thereby significantly enhancing the life and safety of Microtek cables.
