Insulated Power Cables And Wires For Underground And Overhead Power Transmission

Power cables and wires are core carriers for power transmission and distribution, widely used in 10kV–220kV power projects, GIS substations, AIS substations, renewable energy power plants, industrial facilities, urban infrastructure and grid modernization projects. We supply high-quality copper and aluminum alloy cables with advanced production technology, stringent quality control and direct factory prices. Our products support customized designs and one-stop services to meet global engineering standards and personalized project demands.

Copper Cables: The Preferred Choice for High-Reliability Power Transmission

Copper cables feature superior electrical conductivity, stable performance and high safety, making them ideal for high-load, heavy-duty and long-term power transmission applications.

Key Applications

• Substation internal wiring: Equipment connections, busbar leads and grounding systems for 10kV–220kV GIS and AIS substations, ensuring stable high-current transmission in unattended smart substations.
• Urban core infrastructure: Underground cable networks, data centers, hospitals, high-rise buildings and commercial complexes requiring uninterrupted and high-density power supply.
• Heavy industrial fields: Power supply for large motors and precision equipment in mining, chemical and metallurgical plants under high-vibration and heavy-load working conditions.
• Renewable energy projects: Booster station power distribution and grid connection lines for wind farms, solar power stations and energy storage stations.
• Grid renovation and upgrade: These cables replace aging ones to eliminate tripping faults, electric leakage and overheating issues, and extend the service life of power grids.

Core Technical Advantages

• Excellent conductivity: High-purity oxygen-free copper conductors ensure even current flow and low voltage drop, cutting transmission losses by 15–20% compared with those of aluminum cables.
• High safety performance: Eco-friendly flame-retardant and fire-resistant insulation delivers strong resistance to high temperatures, moisture, corrosion and electric breakdown.
• Great bending resistance: They resist cracking during installation and are suitable for cable tray laying, pipe installation, direct burial and overhead laying.
• Strong anti-interference performance: They ensure stable power supply for precision electronic equipment and smart grid systems.
• Long service life: They can operate steadily for over 30 years under normal conditions with low maintenance costs.

Aluminum Alloy Cables: Lightweight & Cost-Effective Power Solutions

Compared with pure aluminum cables, aluminum alloy cables are lighter in weight, better in creep resistance and more cost-effective, making them perfect for conventional power distribution and long-distance power transmission.

Key Applications

• Urban and rural power grid construction: 10kV and below distribution networks, rural electrification projects and long-distance overhead and buried transmission lines.
• Municipal infrastructure: Street lighting, traffic signal systems, bridges, tunnels and sewage treatment plants.
• Light industrial projects: Main and branch distribution circuits for warehouses, factories and commercial buildings.
• Distributed renewable energy: Grid connection lines for small-scale solar and wind power projects.
• Remote area construction: They are ideal for mountainous and rural areas; their lightweight design greatly reduces transportation and on-site installation difficulties.

Core Technical Advantages

• Lightweight design: They are 40%–50% lighter than equivalent copper cables, effectively cutting construction labor costs and lowering load-bearing pressure on towers and cable brackets.
• Superior creep resistance: The optimized alloy structure prevents conductor loosening and joint overheating caused by temperature changes, a common defect of ordinary pure aluminum cables.
• Excellent flexibility: A smaller minimum bending radius enables easy installation in narrow spaces and complex routing layouts.
• Outstanding weather and corrosion resistance: They withstand extreme temperatures, UV radiation, salt spray and chemical erosion to ensure stable outdoor operation.
• Cost-effective performance: Their procurement cost is roughly 30% lower than that of copper cables, fully meeting standard power distribution operation requirements.

Our Core Competitive Strengths
