Choosing Solar Cables: A Comprehensive Guide to Avoid Pitfalls

With the rise of clean energy, solar cables have become a crucial component in solar energy systems, making the selection of high-quality cables increasingly important. The right choice not only impacts system performance but also involves considerations of safety and reliability. This article will provide you with a comprehensive guide to help you make informed decisions when purchasing PV cables and avoid common pitfalls.

1.Understand the Construction of Solar Cables:

First and foremost, it is crucial to grasp the basic construction of solar cables. Typically, they include a conductor, insulation layer, and outer sheath. Conductors are made of highly conductive copper or tinned copper, while insulation layers and sheaths often use cross-linked polyethylene (XLPE) or cross-linked polyolefin (XLPO) known for moisture resistance, UV resistance, and abrasion resistance. However, some manufacturers may compromise on quality by using non-standard rubber materials for cable sheathing, or even low-quality plastic materials, which may lack weather resistance, heat resistance, or oil resistance, leading to potential cable damage. KUKA CABLE consistently utilizes XLPO material, ensuring uncompromised quality and stability in high-temperature environments.

2.Prioritize International Certifications:

UL and TÜV certifications are two crucial international certifications. UL certification ensures that products meet strict safety standards for the U.S. market, while TÜV certification is essential for entering the European market, providing strong guarantees for the quality and safety of products in the European market. KUKA CABLE has obtained numerous certifications, including TÜV, UL, CPR, showcasing its commitment to product quality and safety and providing customers with a more confident choice.

3.Focus on Mechanical Performance:

Mechanical performance includes tensile strength, bending radius, wear resistance, ozone resistance, UV resistance, oil resistance, and fire resistance. These properties directly relate to the installation and use of solar cables. For instance, cables may experience tensile forces, making tensile strength a key indicator. While EN50618 specifies a cable elongation at break of 125%, KUKA CABLE achieves an impressive elongation at break of 185%. This data vividly demonstrates KUKA CABLE's outstanding performance in tensile strength, providing users with a higher level of photovoltaic cables.

4.Understand the Electrical Performance of Cables:

The electrical performance of cables is crucial for ensuring energy transmission efficiency and system effectiveness. Electrical performance covers various aspects, including conductor resistance, rated voltage, insulation resistance, cable capacitance, corona resistance, rated current, cable temperature rise, and resistance to voltage impulses. Among these, conductor resistance is a particularly critical factor as it relates to energy consumption during power transmission.

Additionally, cables must have the ability to operate stably under certain voltage conditions to prevent breakdown during normal operation, avoiding losses and electrical failures. KUKA CABLE places significant emphasis on the electrical performance of photovoltaic cables, subjecting each batch to rigorous testing. For the mentioned electrical properties, we comprehensively record data for easy customer review at any time.

5.Emphasize Environmental Sustainability:

Choosing Solar cables made from recyclable materials helps reduce adverse environmental impacts, aligning with the principles of sustainable development. Furthermore, the introduction of RoHS certification ensures that PV cables do not contain harmful substances, adhering to international environmental standards. As a company committed to responsible manufacturing, KUKA CABLE staunchly supports green environmental practices, not only prioritizing the use of eco-friendly raw materials but also actively engaging employees in various green initiatives, contributing to the sustainable development of the Earth's environment.

6.Select the Appropriate Type Based on Requirements:

Solar cables come in various types, and it is essential to choose the right type based on different application scenarios. For example, waterproof solar cables for use in water-based solar projects or insect-resistant photovoltaic cables suitable for direct burial.

Purchasing Solar cables requires comprehensive consideration of construction, certifications, mechanical and electrical performance, environmental sustainability, and specific type requirements. With advanced technology, high-quality products, and comprehensive services, KUKA CABLE provides reliable solutions for the clean energy industry.
