Mar. 20, 2020

250kw diesel generator set is assembled by Jiangsu Starlight Electricity Equipments Co.,Ltd. in China, our factory was founded in 1974, as one of the biggest supplier, we have focused on high quality generators for more than 43 years.


1.General Features of the 250kw diesel genset

All qualified generator sets are subjected to a comprehensive performance test which includes 50% load, 75% load, 100% load, 110% load and to check, verify that all control systems, alarm and shut-down protection.

Equipped with battery charger and 24V high performance maintenance-free lead-acid starting batteries and connecting cables.

Stainless galvanized zinc plates with strong corrosion-proof.

Vibration isolators between the engine/alternator and base frame.

Equipped with industrial silencer and flexible exhaust hose.

Designed to comply with ISO8528/GB2820.

Powered by Cummins engine NTA855-G1 and Stamford alternator HCI444C1

Water jacket preheater, oil heater and double air cleaner, etc. are available.
