Imported 4RM (4mm²) UV Resistance Tinned Pure Copper PV Cable – Overview
The Imported 4RM (4mm²) UV Resistance Tinned Pure Copper PV Cable is designed for DC-side wiring of solar panels and photovoltaic systems. Built for demanding outdoor environments, this cable ensures stable DC power transmission with excellent resistance against wind, sunlight, rain, and snow.
Key Benefits
- Rated for DC1500V to support modern high-voltage PV string systems.
- Tinned pure copper conductor ensures high conductivity and corrosion resistance.
- Wind proof, sun proof, rain proof, and snow proof construction for outdoor use.
- XLPO insulation and sheath provide strong thermal and mechanical protection.
- UV resistant jacket supports long-term exposure to direct sunlight.
- Low Smoke Zero Halogen design enhances fire and installation safety.
- Operates reliably in extreme temperatures from -40℃ to +90℃.
- High short-circuit temperature tolerance protects during fault conditions.
This PV cable is ideal for high-current DC connections between solar panels, combiner boxes, charge controllers, and inverters in residential, commercial, and industrial solar installations.
