HL220-LJ-134 3.2MW Francis Hydro Turbine Generator Unit High Efficiency Class F Insulation

Product Overview

The HL220-LJ-134 3.2MW Francis hydro turbine generator unit is a complete vertical-shaft mixed-flow generating set developed for small and medium-head hydropower stations. It integrates a stainless-steel Francis runner, a synchronous generator, a microcomputer speed governor, an excitation system and a protection and control system into one reliable package. Every unit is custom-engineered and manufactured in China according to the actual head, flow, grid and climate conditions of the project site, making it an ideal core asset for commercial on-grid power generation.

Core Selling Points

• High Efficiency and Stable Operation: The runner adopts three-dimensional flow-field optimized hydraulic design with low hydraulic loss, delivering a turbine efficiency of over 92% and smooth, stable output across a wide load range. The unit starts and stops smoothly, responds quickly to load changes and operates reliably under continuous full-load conditions.
• Class F Insulation System: The generator is equipped with a full Class F (F/F) high temperature-resistant insulation system, perfectly suited to hot, humid and tropical climates. It effectively prevents insulation aging, moisture absorption and breakdown faults, ensuring long-term safe operation with minimal maintenance.
• Made in China with High Quality: Designed and manufactured in China under a strict ISO9001 quality management system with TUV and BV inspection support. The unit is built from wear-resistant, corrosion-proof materials, offers a service life of 30-50 years and is delivered with complete bilingual documentation and export-grade seaworthy packing.
