The project involves the relocation and reconstruction of high-voltage transmission lines crossing the Yellow River, ensuring safe and efficient power transmission.

Key Project Highlights
 • Voltage Level: 220kV
 • Transmission Lines Involved: Shaomei Line & Shaoqing Line
 • Major Crossing: Yellow River
 • Tower Type: Four-Legged Tubular Steel Tower

The project plays a vital role in supporting urban infrastructure development, ensuring power grid security, and optimizing the regional transmission network.

Construction Plan & Execution

1. Route Planning & Site Analysis

The crossing of the Yellow River presents complex geological and hydrological challenges, requiring:
 • Detailed topographical and hydrological surveys to ensure structural stability.
 • Wind load and flood impact assessments to enhance resilience.
 • Environmental impact evaluations to minimize disruption to local ecosystems.

Advanced GIS (Geographic Information System) modeling was used to determine the optimal tower placement while reducing interference with existing infrastructure and waterways.

2. Tower Construction & Foundation Engineering

Given the high-voltage requirements and river-crossing challenges, the project uses four-legged tubular steel towers, which offer:
 • High structural strength to withstand riverbank erosion and extreme weather conditions.
 • Aerodynamic design to reduce wind resistance and minimize oscillations.
 • Corrosion-resistant coatings to ensure long-term durability in humid environments.

The tower foundations were designed based on ground conditions:
 • Deep-pile foundations for stability in soft riverbank soils.
 • Reinforced concrete bases to withstand high-load transmission.
 • Anti-scouring protection measures to prevent foundation erosion due to river currents.

Helicopter-assisted assembly was utilized to improve efficiency and reduce construction time in difficult-to-access areas.

3. Conductor Installation & Power Line Relocation

To ensure efficient and low-loss power transmission, the project adopted:
 • High-performance aluminum alloy conductors with excellent conductivity.
 • Weather-resistant composite insulators to enhance safety and durability.
 • Electromagnetic shielding measures to minimize interference with surrounding infrastructure.

Tension stringing techniques were employed to maintain precise conductor alignment, reducing transmission losses and enhancing grid performance.

4. Integration with the Power Grid

The relocated transmission lines are seamlessly integrated into the Jinan regional power grid, ensuring:
 • Stable voltage regulation with advanced relay protection systems.
 • Reactive power compensation to optimize grid efficiency.
 • Smart monitoring technologies for real-time performance tracking.

The new infrastructure enhances grid flexibility and supports future urban expansion projects in the region.
