A "Generator" is actually a combination

of two machines, Engine and Alternator. Engine produces kineticpower by converting potential energyinto mechanical energy, i.e., fuel(Diesel, Gas, ! , etc.# which haspotential energy into revolution of

crank shaft which is kinetic ormechanical energy. $he crank %haft ofthe Engine shifts power to the rotor ofthe Alternator. $he alternator thenconverts this mechanical energy intoelectric energy. $his process is donethrough combustion of fuel. $hat iswhy these generators are called

GENERATOR MARKET INPAKISTAN

Due to load shedding generatorsimport to akistan and generator

prices in akistan have boomed upsince last five years.

$here are a number of internationalcompanies offering their manufacturedbrand new generators in akistan.rominent are &A$E- 688A-,&'446+%, E-96+%, !G )68% +,

DA+: , etc. $he prices thesecompanies offer vary a lot due to*uality difference.

eople also import used generators inakistan mostly having the samebrand names. $hese generators aredifferent in their status and prices.

'p to 211 k/A ratings are assembledin akistan. $hese are coupledgenerators with very effective pricesfor local users.

%imilar to all other fields, &hina is alsogetting dominant in generatormanufacturing around the globe.

Almost all ratings of &hinamanufactured generators can bebought here in local market. $headvantage being the lesser prices.

$here are a number of options available inakistan for some one who plans to buyalternative generator power, i.e., alternative to)apda or Grid power.

CATAGORIES

Generators can be divided in sub categories,e.g., in accordance with location, rated powerre*uired, nature of usage, period of usage, etc.!irstly generators can be brand new imported,locally refurbished, be imported in usedconditions, etc., with a lot of variations in theirprices. A user can choose a machine inaccordance with his budget.
