从China供应商批量进口4mmâ²â Twin Core Solar Cable

This 4mm² twin core solar cable from Zhejiang Qinshan Cable Co., Ltd features tinned annealed copper conductors, stranded for flexibility and enhanced conductivity. The insulation and jacket are made from polyolefin copolymer, electron-beam cross-linked for superior durability, UV resistance, and ozone resistance. Designed for photovoltaic systems, the cable operates within a conductor temperature range of -40°C to +120°C and an ambient temperature range of -40°C to +90°C.

The cable meets a nominal voltage rating of Uo/U 600/1000V AC and 1000/1800V DC, with a test voltage of 6500V at 50Hz for 5 minutes, as per EN 50618:2014. It complies with fire performance standards IEC 60332-1, smoke emission standards IEC 61034 and EN 50268-2, and low fire load requirements under DIN 51900. Its cross-linked polymer construction ensures long-term resistance to hydrolysis and high temperatures, with a service life exceeding 25 years at 90°C.

Common applications include wiring for photovoltaic power stations, terminal blocks, connectors, inverters, and junction boxes. The cable’s flexibility and resistance to environmental stressors make it ideal for outdoor installations, where exposure to sunlight, moisture, and temperature fluctuations is constant. Buyers in the renewable energy sector prioritise this cable for its reliability in harsh conditions and compliance with international safety standards.
