400mm2 Stranded Copper Earthing Electrical Wire 450/750 Voltage Rating, Yellow/Green | Jeddah Cables

This 400mm² stranded copper earthing wire, rated at 450/750 volts, is a cornerstone of safe electrical installations across Qatar. Manufactured by Jeddah Cables, it combines high conductivity with robust PVC insulation, ensuring dependable performance in Doha's humid coastal climate and the dusty inland conditions of Al Rayyan and Al Wakrah.

The PVC insulation acts as a formidable barrier, shielding the copper core from moisture, corrosion, and mechanical stress. This not only prevents current leakage but also extends the wire's service life, making it a smart investment for contractors and facility managers who prioritize long-term reliability.

In the event of a short circuit, this grounding wire provides a safe, low-resistance path for fault currents to dissipate into the earth, protecting personnel and equipment from electric shock and fire hazards. Its flexible stranded construction simplifies handling and installation, even in tight spaces common in retrofit projects.
