AI Technical Summary

⚠Technical Problem

Existing photovoltaic power station cables have insufficient flame retardant properties, making them prone to combustion and producing dense smoke and toxic gases. They also lack anti-bite properties and cannot provide early warning, resulting in severe fire losses and difficulty in detecting bite damage, leading to low inspection efficiency.

⚗Method used

It adopts a composite structure of an inner chemical repellent layer, a middle intelligent early warning layer and an outer metal armor layer. The inner layer achieves long-term anti-bite effect through slow-release microcapsule repellent, the middle layer achieves real-time early warning through conductive fiber mesh and position sensing unit, and the outer layer constructs a flame-retardant barrier across the entire temperature range through composite flame retardant, combined with salt spray resistant and UV resistant modifiers to improve weather resistance.

🎯Benefits of technology

It achieves long-term anti-bite and real-time early warning for cables, improves flame retardant performance, reduces fire losses, accurately locates the damaged location, improves inspection efficiency, adapts to complex outdoor environments, and extends service life.
