Reborn Energy Xinjiang Tianshan Northern Foot New Energy Base Project Wind Farm 35kV & 3kV Power Cable Procurement

The Xinjiang Tianshan Northern Foothills New Energy Base Project is a key national power project under the 14th Five-Year Plan and a core supporting facility for the "Xinjiang to Chongqing" strategy. Developed and constructed by Xinjiang Renewable Energy Power Development Co., Ltd., the project is a large-scale integrated energy base combining wind power, photovoltaic power, solar thermal power generation, and energy storage. Located in the heart of the Hami Gobi Desert in Xinjiang, the base has a total installed capacity of 4100 MW, including 2800 MW of wind power, 1200 MW of photovoltaic power, 100 MW of solar thermal power, and a supporting energy storage capacity of 800 MW/3200 MWh.

As a landmark green power project in the "sand-gobi-arid" region, this project transmits clean electricity to central China via the Hami-Chongqing ±800kV ultra-high voltage direct current transmission line, with an average annual grid-connected power generation of 9.786 billion kilowatt-hours. This will significantly optimize the national energy allocation and reduce carbon emissions by 7.61 million tons annually. The project requires highly reliable, flame-retardant, corrosion-resistant, and weather-resistant medium-voltage cables to cope with the extreme environmental conditions of the Gobi Desert, such as large temperature differences, strong winds, sandstorms, and drought.

Jinhong has been selected as the exclusive supplier of 35kV and 3kV cross-linked polyethylene (XLPE) power cables for this strategic new energy base.

Cable Models and Core Performance Advantages

Jinhong provides a range of 35kV medium-voltage and 3kV low-voltage cross-linked polyethylene (XLPE) cables optimized for power harvesting, grid connection, and auxiliary systems in wind farms, performing exceptionally well even in harsh desert environments.

• Aluminum Conductor Design: 30% lighter than copper conductors, significantly reducing material and installation costs for long-distance power transmission.
• Steel Tape Armor (23) Structure: Excellent resistance to pressure, impact, and soil corrosion, making it ideal for direct burial in the Gobi Desert.
• Class C Flame Retardant: Meets stringent fire safety standards for large-scale power collection lines.
• Cross-linked Polyethylene Insulation: Long-term operating temperature up to 90℃, short-circuit withstand temperature up to 250℃, ensuring stable operation under extreme high and low temperature conditions.

Application: 35kV main power collection lines connecting wind turbine generators and booster stations, suitable for long-distance direct burial in the Gobi Desert.

• High-purity oxygen-free copper conductor: Excellent conductivity, low power loss, ensuring efficient energy transmission.
• Armored waterproof design: Double-layer steel tape armor + PE inner sheath, resisting sandstorm abrasion and groundwater moisture.

Applications: Critical 35kV grid-connected lines and substation main feeders requiring high current carrying capacity and reliability.

• Steel wire armor (63) structure: Enhanced tensile strength, suitable for laying environments with complex terrain, large undulations, and long spans.
• Excellent mechanical flexibility: Withstands ground subsidence and minor seismic activity in the Gobi Desert.

Applications: 35kV lines traversing Gobi depressions, undulating terrain, and requiring high tensile strength.

• 1.8/3kV Rated Voltage: Suitable for wind turbine auxiliary systems, field power distribution, and equipment power supply.
• Flame Retardant Armor: Ensures safety and durability in complex wind farm environments.

• High Mechanical Strength: Withstands vibrations and mechanical stresses within the wind turbine tower.

Applications: Powers wind turbine nacelles, control systems, and auxiliary equipment.

• Extreme Climate Conditions: The Gobi Desert presents challenges such as extreme temperatures (-40°C to +60°C), intense sandstorms, high UV radiation, and drought, thus placing extremely high demands on the weather resistance, UV resistance, and aging resistance of cables.
• Long-Distance Direct Burial and Complex Terrain: Wind farms cover a wide area, requiring long-distance direct burial. The undulating terrain and poor soil conditions further necessitate higher requirements for the mechanical strength, corrosion resistance, and compressive strength of cables.
• High Reliability to Meet New Energy Grid Connection Needs: As a national strategic green energy base, wind farms must achieve zero major failures during decades of operation, thus requiring extremely high electrical performance stability and service life of cables.
• Large Order Volume and Tight Delivery Schedule: Orders exceeding RMB 130 million require large-scale production capacity and precise delivery cycles to meet the phased construction plan of the project.
• Strict fire safety and environmental protection standards: Large-scale wind farms require the use of flame-retardant (Class C) cables to prevent the spread of fire in the event of a fault, thereby ensuring the overall safety of the project.

• Complete Medium and Low Voltage Cable Solutions for New Energy: Covering a full range of products for 35kV/10kV/3kV wind farm power collection, grid connection, and auxiliary systems, providing one-stop procurement services for EPC contractors and new energy developers.
• Superior Performance in Extreme Environments: Utilizing special formulas for extreme environments such as the Gobi Desert, high temperatures, extreme cold, sandstorms, and ultraviolet radiation, our products have been validated in multiple new energy base projects in Northwest China.
• Strict Quality Control and Adherence to International Standards: Using high-purity oxygen-free copper/aluminum conductors and imported XLPE insulation materials. Full-process quality inspection, including withstand voltage, partial discharge, and flame retardant testing. Compliant with IEC 60287, GB/T 12706, and GB/T 19666 standards, supporting global project bidding.
• Large-scale production, on-time and reliable delivery: With a smart manufacturing base, the annual production capacity exceeds 10,000 kilometers of medium-voltage cables, capable of handling large orders exceeding RMB 100 million and ensuring on-time delivery.
• Providing full-cycle technical support for new energy projects: Providing free cable selection, laying scheme optimization, and technical consultation for wind power/photovoltaic power station projects. Providing on-site installation, testing, and acceptance technical guidance. Providing complete English technical documents and qualification certificates for international projects.
