Frequently Asked Questions
1. What are the key benefits of using XLPE insulation for solar cables?
XLPE (Cross-linked Polyethylene) provides superior thermal resistance, excellent electrical insulation properties, and high resistance to UV radiation and moisture, ensuring a lifespan of over 25 years in harsh outdoor environments.
2. Why is tinned copper preferred over bare copper for solar applications?
Tinned copper prevents oxidation and corrosion, especially in humid or high-temperature environments. This maintains excellent conductivity and makes soldering connections much easier over the cable's long-term use.
3. What temperature range can these PV cables withstand?
These solar cables are designed to operate in extreme conditions, typically withstanding ambient temperatures from -40°C to +90°C, with a maximum conductor temperature of 120°C.
4. Are these cables compatible with all standard MC4 connectors?
Yes, our solar DC cables are manufactured to international standards (PV1-F), making them fully compatible with MC4 and other standard solar connectors used in photovoltaic systems.
5. How do you ensure the quality of the solar cables before shipment?
We perform rigorous testing using over 240 inspection instruments. This includes pre-production sample approval and a final 100% inspection before shipment to ensure compliance with all electrical and safety standards.
6. What certifications do your solar products hold?
Our manufacturing processes are highly regulated, holding numerous patents and operating under an ETL satellite laboratory status, ensuring our products meet global export standards for over 100 countries.
