Frequently Asked Questions

QTwin Core and Single Core: Which one to choose?

A:Two-core cables integrate the positive and negative wires within the same sheath, offering the greatest advantage of high installation efficiency and extremely neat wiring, making them ideal for distributed systems in RVs, yachts, or homes with limited space. In contrast, single-core cables, while requiring two separate wiring operations, offer greater physical flexibility and superior performance in conduit installation and heat dissipation, making them more commonly used in large-scale ground-mounted power plants or complex industrial installation environments.

QIs twin core solar cable durable and safe for outdoor use?

A:As long as the product complies with photovoltaic industry standards such as EN 50618 or IEC 62930, the safety of a two-core cable is no different from that of a single-core cable. Because it uses high-temperature resistant and UV-resistant XLPO (cross-linked polyolefin) material, and each core has an independent insulation layer that works in conjunction with the outer sheath to form "double protection," it can withstand operating voltages up to DC 1500V and maintain a service life of up to 25 years in harsh outdoor environments.
