125°C Accelerator Irradiation Cross-linked LSZH Flame Retardant Insulation and Sheathing Material Released, Empowering Long-term Safe Operation of Photovoltaic Systems

Driven by the global dual-carbon strategy and the rapid expansion of photovoltaic new energy markets, outdoor PV cables face extreme operating conditions such as long-term high-temperature exposure, strong ultraviolet radiation, alternating cold and heat, and humid weather. Traditional cable materials with temperature resistance below 105°C suffer from poor weather resistance, rapid aging, and insufficient flame retardancy, failing to meet the 25-year long service life standard of photovoltaic power stations. To solve the industry pain points, our new 125°C Accelerator Irradiation Cross-linked LSZH Flame Retardant Insulation and Sheathing Material has been officially launched, specially developed for photovoltaic system supporting cables.
Adopting high-energy accelerator electron beam irradiation cross-linking technology, the material achieves a temperature resistance upgrade up to 125°C, integrating low-smoke zero-halogen flame retardant and high weather resistance formulas. It integrates insulation and sheathing performance in one material, becoming an upgraded and exclusive solution for high-performance PV cables.
Core Product Advantages
1. 125°C Ultra-high Temperature Resistance
The precise accelerator irradiation cross-linking forms a dense and stable 3D molecular network structure. The material supports long-term continuous operation at 125°C and adapts to a wide temperature range of -40°C to 125°C. It effectively avoids softening, deformation and aging failure caused by high temperature overload, fully meeting the 25-year long-term operation requirements of photovoltaic power stations.
2. Stable Cross-linking & Superior Mechanical Performance
With accurate dose control of high-energy accelerator irradiation, the material features uniform cross-linking degree and stable batch quality. It delivers excellent tensile resistance, compression resistance, wear resistance and crack resistance, effectively resisting external extrusion and wind-sand abrasion during PV cable laying and outdoor operation.
3. Integrated Insulation & Sheathing Design
Professional integrated formula for PV cables ensures excellent compatibility between insulation and sheathing layers. It supports high-speed double-layer co-extrusion production with smooth extrusion performance, no bubbles or surface defects, greatly improving finished product yield and reducing overall production costs for cable manufacturers.
4. LSZH Eco-friendly & High Flame Retardancy
Adopting halogen-free, lead-free and heavy metal-free environmental formula, the material complies with IEC 60754 and EU RoHS standards. It features low smoke density and non-toxic combustion, effectively restraining flame spread and avoiding secondary equipment corrosion and environmental pollution, meeting strict fire safety standards for PV and energy storage power stations.
5. Outstanding Weather & Aging Resistance
Equipped with special anti-UV, anti-ozone and hydrolysis-resistant additives, the material maintains stable performance after long-term outdoor exposure, avoiding pulverization and cracking. It is perfectly suitable for distributed rooftop PV, desert PV, mountain PV, water PV and other complex outdoor scenarios.
Application & Market Prospect
With the continuous upgrading of global new energy construction, high-temperature resistant, weather-resistant and environmentally friendly LSZH PV cable materials have become mainstream demand. This 125°C accelerator irradiation cross-linked material is widely used in PV DC cables, AC connection cables and energy storage supporting cables, providing reliable material support for the safe and long-term operation of global photovoltaic power projects.
