Shanghai Dongfeng 250 kVA Diesel Generator

Shanghai Dongfeng 250 kVA Diesel Generator

What defines this set is first of all its mechanical layout. An inline six-cylinder SDEC block, fed by a turbocharger and an aftercooler, carries the high-compression diesel cycle a genset of this size depends on. The unit is rated at 250 kVA standby and 225 kVA prime, and the gap between those two figures is exactly the margin the engine keeps for itself once a site runs under continuous load.

Engine

The engine is an SDEC SC9D250D2. Its core mechanical data are a 6-cylinder inline arrangement, 8.8 L displacement, a 114 x 144 mm bore and stroke and a 16.5:1 compression ratio. Aspiration is turbocharged and aftercooled. Fuel consumption is given as 52 L/h at 100% load and 39 L/h at 75% load.

Alternator and Electrical Data

The alternator supplies 400/230 V at 50 Hz in a three-phase configuration, rated at a 0.8 power factor. Standby output is 250 kVA / 200 kW / 361 A, while continuous operation is rated at 225 kVA / 180 kW / 325 A. Winding insulation is class H and the protection rating is IP23.

Installation and Use

In canopy form the set measures 3400 x 1150 x 1750 mm, while the open-type version has a footprint of 2600 x 1150 mm. That difference is what drives the layout of the plant room or the concrete pad. The generator carries a 24-month warranty, is of Turkish origin and is listed under stock code NDX-SDF-250.
