Project Overview

The 500kV Kyrgyzstan Datka-Keming Transmission Line is a landmark energy cooperation project between China and Kyrgyzstan, constructed by TBEA Co., Ltd. as part of efforts to improve Kyrgyzstan’s Southern Grid. With a total contract value of $0.39 billion USD and a 36-month construction period, this project is the largest energy infrastructure collaboration between the two nations and a crucial milestone for the Kyrgyzstan State Grid.

The project aims to:
• Enhance power transmission capacity between southern and northern Kyrgyzstan.
• Strengthen grid stability by reducing dependence on neighboring countries for power transmission.
• Support regional economic development by ensuring a reliable electricity supply for industries and households.

The Datka-Keming line integrates Kyrgyzstan’s previously fragmented grid into a unified national network, improving energy security, transmission efficiency, and long-term economic stability.
Construction Plan & Execution

1. Route Planning & Site Selection

The transmission line spans mountainous terrains, valleys, and river crossings, requiring:
• Detailed topographical surveys to optimize the route.
• Seismic risk assessments to ensure infrastructure resilience.
• Environmental impact studies to minimize ecological disruption.

Given Kyrgyzstan’s rugged geography, the project incorporated specialized engineering solutions to tackle the high-altitude and extreme weather conditions.
2. Tower Erection & Foundation Engineering

To ensure structural stability and longevity, the transmission towers were designed using:
• High-strength steel to withstand heavy winds and snow loads.
• Deep-pile and rock-anchor foundations for stability on mountainous terrain.
• Pre-fabricated tower components for faster and safer assembly.

Helicopter-assisted tower installation was employed in remote and inaccessible locations, reducing environmental impact and ensuring efficient construction progress.
3. Conductor Stringing & Insulation

The transmission line utilizes advanced conductors and insulation technology, including:
• High-performance aluminum alloy conductors for reduced energy loss.
• Anti-icing and anti-corrosion coatings to withstand extreme cold conditions.
• Composite polymer insulators for improved durability and electrical insulation.

Specialized tension stringing methods ensured precise conductor alignment and minimal transmission losses, optimizing overall grid efficiency.
4. Grid Integration & Substation Construction

The project included the integration of the Datka and Keming substations, enabling:
• Stable voltage regulation across the national grid.
• Seamless energy transfer between the north and south without reliance on external grids.
• Smart relay protection and automation for real-time system monitoring.

With the introduction of SCADA (Supervisory Control and Data Acquisition) systems, operators can monitor power flow, detect faults, and optimize grid performance remotely.
