4mm2 PV1-F Solar Cable Tinned Copper XLPO Insulation UV Resistant for Solar DC Systems

4mm2 PV1-F Solar Cable — Tinned Copper, XLPO Insulated, UV & Weather Resistant

This 4mm2 PV1-F solar cable is purpose-built for photovoltaic DC systems. It features a flexible tinned copper conductor and a dual XLPO (cross-linked polyolefin) insulation and sheath, delivering excellent UV and weather resistance for continuous outdoor exposure. The halogen-free, flame-retardant construction stays flexible for easy routing across solar panels, combiner boxes, inverters and energy storage systems, with a rated service life of 25 years.

Key Selling Points

• Tinned Copper Conductor — fine stranded Class 5 tinned copper resists oxidation and corrosion for stable conductivity.
• XLPO Insulation & Sheath — electron-beam cross-linked, flame retardant and halogen free.
• UV & Weather Resistant — ozone, abrasion and ageing resistant, suitable for long-term outdoor installation.
• Flexible PV Cable for Solar DC Systems — high flexibility simplifies installation in tight and elevated layouts.

A Dedicated Photovoltaic Cable Manufacturer

As a dedicated photovoltaic cable manufacturer, we design and produce PV1-F solar cables engineered for the demands of modern solar DC systems. On our own extrusion and electron-beam cross-linking lines, every cable is built with fine-stranded tinned copper conductors and halogen-free XLPO insulation and sheath, delivering stable conductivity, UV and weather resistance, and a service life of up to 25 years. Each production batch is tested for conductor resistance, high-voltage withstand and dimensional tolerance before shipment, and our PV cables carry TUV, CE and RoHS certifications. We supply 4mm², 6mm² and 10mm² PV1-F cables in DC 1500V grade to solar EPCs, distributors and system integrators worldwide, with flexible OEM/ODM support, free samples and a monthly capacity of 800–1500 km. Working directly with a manufacturer—not a trader—gives you consistent quality control, factory-direct pricing and full technical support for your solar projects.
