Y/G Insulated Copper Clad Steel Strand Conductor | High-Performance Grounding Wire

In critical grounding and earthing applications where safety, conductivity, and long-term durability are paramount, the Y/G Insulated Copper Clad Steel Strand Conductor (also known as yellow-green PVC insulated CCS stranded grounding wire) stands out as a high-performance, cost-effective solution. This advanced composite conductor combines the superior electrical conductivity and corrosion resistance of copper with the high tensile strength and rigidity of a steel core, all protected by a durable yellow-green PVC insulation layer for easy identification and enhanced mechanical protection.

Widely trusted in lightning protection systems, railway electrification, petrochemical plants, and power distribution networks, this Y/G insulated CCS strand conductor delivers reliable performance in demanding environments while significantly reducing material costs compared to pure copper grounding conductors.

Primary Applications

The RLB Y/G Insulated Copper Clad Steel Strand Conductor is specifically designed for high-reliability grounding and earthing systems:

• Lightning protection grounding for HF coaxial cables, communication towers, broadcast systems, and renewable energy installations
• Earthing systems in electrical railways, light metro, high-speed rail, and metro infrastructure
• Electrostatic grounding and safety earthing in petrochemical plants and heavy industrial facilities
• Ground lines for power transmission, distribution networks, and substations
• Safety grounding in data centers, smart buildings, and critical infrastructure

Its outstanding combination of high tensile strength, stable conductivity (30–40% IACS), and superior corrosion resistance makes it ideal for both above-ground and buried installations exposed to vibration, mechanical stress, soil acidity, and extreme weather.

Product Structure & Construction

Manufactured through a precise, multi-step process using RLB’s advanced cable production technology:

• Stranded Copper Clad Steel Core: Multiple high-quality CCS wires are concentrically stranded on precision wire stranding machine and bunching machine equipment to form a flexible yet high-strength conductor.
• Yellow-Green PVC Insulation: A uniform layer of high-grade PVC compound is extruded over the stranded core, delivering excellent electrical insulation, UV resistance, chemical resistance, and immediate Y/G color coding per international safety standards.
• Metallurgical Bonding: The copper cladding is permanently bonded to the steel core, preventing delamination under mechanical or thermal stress.

This sophisticated construction achieves the ideal balance of electrical performance, mechanical robustness, and long-term reliability.

Standards & Quality Compliance

All RLB Y/G Insulated Copper Clad Steel Strand Conductors are produced in strict accordance with:

• GB2951-1997 (Test methods for PVC insulated cables and wires)
• GB5023-1997 / GB/T 5023-2008 (Polyvinyl chloride insulated cables up to 450/750 V)
• Equivalent international standards including IEC 60227 and ASTM B227/B228 for copper-clad steel conductors
