L12V200ZLT-2 Natural Gas Engine Generator
Jichai Brand generating set is designed and manufactured to be high quality, long usage life, easy operation, low maintenance cost, high intelligence with low engine speed, low fuel consumption, low gas quality requirement, tough environmental adoptability, high stability and low fluctuation. The generating set is desirable for industrial power solution. The genset can either transfer electricity directly to load or be combined in a power station with two or more than two sets. They can be used as normal and stand-by power in oil field, factory, resource development base, etc.
1000GF-T(1000kW) natural gas generating set are powered by model L12V200ZLT-2 gas engine produced by our company. Complying with National Standard “GB2820 General Specification for Industrial Frequency Diesel Generating Sets（eqv ISO 8528）” and with reference to “IEC34-I” rotary generator standard, the sets are equipped with high quality alternator of both home & abroad and self-made control panel according to customers requirement.
L12V200ZLT-2 natural gas engine is adopted advanced governor of American WOODWARD Company. It is the engine that mixes air and fuel before turbocharger. The power performance, fuel economy and reliability of the gas engine reach world advanced level by adopting world advanced outer mixing mode, electronic control technology and lean-burnt strategy.
