Project Overview

The 500kV Datka–Keming Transmission Line Project is a key energy cooperation initiative between China and Kyrgyzstan, constructed by TBEA Co., Ltd. as part of efforts to enhance the performance and connectivity of Kyrgyzstan’s southern and northern power grids. With a contract value of approximately USD 390 million and a construction timeline of 36 months, the project represents a major infrastructure upgrade within the national grid development framework.

The primary goals of the project include:

• Enhancing power transmission capacity between southern and northern regions.

• Improving grid stability and reducing reliance on external transmission networks.

• Supporting regional development by ensuring a more dependable electricity supply for residential, commercial, and industrial users.

By integrating the Datka and Keming substations, the project contributes to the creation of a unified national transmission system, increasing energy reliability and supporting long-term energy planning.

Construction Plan & Execution

1. Route Planning & Terrain Adaptation

The transmission line route spans mountainous regions, river valleys, and high-altitude zones. To address the diverse landscape, the following measures were implemented:

• Comprehensive topographical and geological surveys.

• Seismic risk evaluations for safe infrastructure deployment.

• Environmental assessments to reduce disruption to local ecosystems.

Engineering designs were tailored to Kyrgyzstan’s terrain and climate, supporting safe and efficient construction under complex natural conditions.

2. Tower Construction & Foundation Design

Transmission towers were built using:

• High-tensile steel structures, designed for snow, wind, and altitude-related loading.

• Rock-anchored and deep-pile foundations for geotechnical stability.

• Modular tower components to facilitate transport and assembly.

Helicopter-assisted construction was applied in remote areas, improving installation efficiency while reducing the impact on sensitive landforms.

3. Conductor Installation & Insulation Systems

Advanced installation techniques ensured optimal line performance:

• Aluminum alloy conductors were used for low energy loss and high strength.

• Protective coatings were applied for anti-corrosion and anti-icing performance.

• Durable composite insulators supported reliable electrical insulation in extreme conditions.

Controlled-tension stringing was adopted to ensure proper conductor alignment, improving efficiency and minimizing mechanical stress.

4. Substation Integration & Grid Connection

The integration of the Datka and Keming substations provided:

• Stable voltage management across regional networks.

• Reliable north–south power transfer without cross-border dependencies.

• Digital relay protection and automation systems for remote monitoring and control.

SCADA systems were deployed to enable real-time operational visibility and improve response times in fault scenarios.
