Buy & Import 4mm² Twin Core Solar Cable from Zhejiang Qinshan Cable Co., Ltd - Wholesale Supply

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.

Frequently Asked Questions About 4mm² Twin Core Solar Cable from Zhejiang Qinshan Cable Co., Ltd
The conductor is made from tinned annealed copper, stranded to enhance flexibility and conductivity. Tinning the copper improves corrosion resistance, which is critical for long-term outdoor use in solar installations.

Sourcing 4mm² Twin Core Solar Cable from Zhejiang Qinshan Cable Co., Ltd - China Import Guide

Before ordering, confirm that the cable’s voltage rating and temperature range align with your photovoltaic system’s specifications. Request a certificate of compliance for the relevant standards, such as EN 50618:2014, IEC 60332-1, and DIN 51900, to ensure the product meets your project’s safety and performance requirements. Verify the conductor’s cross-sectional area and stranding to match your system’s current-carrying capacity.

Discuss logistics options, including Incoterms like FOB Ningbo or CIF to your port, as Jiaxing is near major shipping hubs in Zhejiang. Clarify lead times, which may vary based on order volume and customisation, and agree on payment terms that mitigate risk, such as a letter of credit or a staged payment schedule tied to production milestones.

Quality checks should include inspecting the cable for consistent stranding, proper tinning of the copper conductors, and the integrity of the cross-linked jacket. Request a pre-shipment inspection report and ensure all documentation, including test certificates and compliance declarations, is provided in English. For large orders, consider third-party testing to verify the cable’s performance under extreme conditions.
