This complete 3D scene covers the entire main powerhouse of a large hydropower station, including indoor factory building space, overhead crane, floor operation platform, and multiple sets of fully assembled vertical hydro-generator units.Each generating unit is a vertically arranged integrated structure, which is divided into four core layers from top to bottom:

1.Floor Operation Layer: Central unit control housing, safety guardrail, stair access and on-site electrical control cabinet;

2.Generator Upper Section: Stator & rotor winding assembly, external cooling shutter panels and fixed support frame;

3.Thrust Bearing & Transmission Section: Main thrust bearing base, hydraulic governor actuator and main drive shaft connection structure;

4.Water Turbine Flow Passage Layer: Volute spiral water inlet casing, fixed guide vanes, rotating runner, and curved tapered draft tube for water drainage after power generation.
