Mongolia 220/110/35KV Substation Extension Project - Cables Supply

Recently, GRAND CABLE signed another supply contract with a Mongolian engineering contractor to continue supplying special low-temperature resistant cables for the "Sergelen" 220/110/35kV substation project in Mongolia. This new agreement, which is believed to be for the expansion of the substation, further deepens the cooperation between the two parties.

The Sergelen substation is located in Sergelen soum, Tuv province, Mongolia, near the Khushig Valley where the "Chinggis Khaan" International Airport is situated. With an installed capacity of 2×125 MVA, the project is designed to provide power supply to the planned new towns including "AeroCity," Logistics Center, New Zuunmod, and Maidar. The project owner is the Mongolian Ministry of Energy. GRAND CABLE completed the first batch of cable supply last year, and this newly signed contract is expected to be for the expansion phase of the substation.

GRAND CABLE's products include low-voltage power cables and control cables designed for extreme environments, with a cold resistance rating of -40°C. These cables will be primarily used in the substation's secondary protection systems, which are crucial for transmitting critical monitoring signals and control commands to ensure the safe and stable operation of the power grid. The expansion project has the same high requirements for technical standards and reliability of cable products as the first phase.

According to previously released information from the engineering contractor, the main tasks completed in the first phase of the substation project include: assembly and installation of 220/110/35kV overhead distribution equipment (including testing and commissioning), complete relay protection installation and equipment debugging, construction of access roads and drainage channels for the substation, and construction of the substation's control building. Completion of the expansion phase will further enhance the power supply capacity of the region.

This project is one of the key initiatives in Mongolia's efforts to enhance the resilience and reliability of its national power grid. In recent years, driven by growing electricity demand from mining operations and urban population growth, and aiming to optimize its energy mix, Mongolia has been actively modernizing and expanding its power infrastructure. A particular focus has been placed on strengthening the Central Energy System and improving grid interconnection and stability in remote areas. These development efforts have created a continuous demand for transmission and distribution equipment capable of withstanding the extreme low temperatures of the region's continental climate.

As the system integrator, the Mongolian engineering contractor conducted rigorous evaluations of product quality, technical standards, and environmental adaptability during the supplier selection process. GRAND CABLE,凭借 with its stable product performance and technical expertise demonstrated in the first batch of supply, was once again selected as the cable supplier for this expansion project. A representative of GRAND CABLE stated: "Being awarded consecutive supply contracts for the same key project reflects our customer's strong trust in our product quality and technical capabilities. We remain committed to high manufacturing standards and to providing reliable, durable cable solutions for global energy infrastructure construction."

The -40°C cold-resistant cables supplied by GRAND CABLE are specifically engineered to meet the stringent standards required for power construction in high-altitude and cold regions. This renewed contract further solidifies the cooperative relationship between the two parties and demonstrates the continued value of professional cable suppliers in supporting global energy infrastructure development.
