Key Advantages
Reliable Grounding Performance
A grounding cable must provide stable electrical connection over long-term service. This cable uses flexible tinned copper conductors, helping improve conductivity and corrosion resistance, especially in demanding installation environments.
UV Resistant for Outdoor Use
The XLPO insulation offers good resistance to sunlight, heat, and weather exposure. It is suitable for outdoor electrical systems, PV projects, energy storage equipment, and other applications where cables may be exposed to changing site conditions.
Low Smoke Zero Halogen Material
The insulation material is low smoke zero halogen, which helps reduce smoke and corrosive gas release in case of fire. This is especially important for electrical cabinets, indoor wiring areas, and projects with higher safety requirements.
Easy Identification and Installation
The green/yellow jacket clearly identifies the cable as an earth conductor. Its flexible structure also makes routing, bending, and connection easier during installation.
