Product Introduction

The 6.6kV Diesel Generator Set is designed for large-scale industrial, infrastructure, and utility applications requiring stable medium-voltage power. It is particularly suitable for heavy loads and long-distance power transmission where low-voltage systems are inefficient.

Combining a high-performance diesel engine, a 6.6kV alternator, and an intelligent control system, this generator set minimizes transmission losses and delivers reliable power for both continuous operation and emergency backup. It can operate as a standalone unit or be integrated into parallel and complex power distribution systems.

Power Challenges We Solve

Large-scale projects often face the following power challenges:

Long-distance power transmission with high energy loss

High startup current for large motors and equipment

Limited grid capacity or unstable medium-voltage supply

Strict requirements for system safety and reliability
