An alternator is a generator of electric power in a car and is a major component of the vehicle's charging system. When an engine is running, the alternator charges the battery and supplies additional electric power for the vehicle electrical systems. To drive the engine alternator belt is used. The spinning is made possible by the alternator Belt that runs from the pulley on the alternator to the crank-shaft without the alternator Belt the battery would die after a short amount of driving. The type of the Belt around the alternator depends solely on the make of the vehicle. Older cars are fitted with a Cogged Belt for the alternator, while newer cars use Poly-V Belts as an alternator Belt.

Features
- Best suited for next-generation, high speed engines
- Cog profile offers enhanced flexibility and heat dissipation rate
- Higher power transmission capacity, best suited for smaller diameter pulleys
- Engineered and chemically treated modulus & low stretch tensile cords for higher loads, without stretch
- Compounded for better grip and lateral rigidity
- Excellent resistance to oil and heat
- Suitable for HEMM (Heavy earth moving machinery) applications
Temperature range: -25°C to +100°C and -45°C to +120°C in case of EPDM Belts
