twin core pv cable 6mm

The 6mm twin core PV cable is a crucial component in photovoltaic systems, combining high - quality characteristics with specific specification advantages. Each core of the cable has a cross - sectional area of 6 square millimeters, designed specifically for efficient and stable power transmission.

I. High - Quality Materials Ensure Performance

1.1 Excellent Conductors

High - purity oxygen - free copper with a purity exceeding 99.97% is used as the conductor material and is usually tin - plated. This high - grade copper significantly reduces resistance, enabling efficient power transmission with minimal power loss at the 6mm core size. The tin - plating layer effectively resists oxidation. Even in long - term humid and high - humidity outdoor environments, it can ensure the cable operates stably for many years and maintains a low - resistance state.

1.2 Advanced Insulation and Sheath

Inner Insulation: Cross - linked polyethylene (XLPE) or cross - linked polyolefin (XLPO) is selected as the inner insulation material. In the twin - core structure with 6mm cores, this insulation layer can reliably isolate the current, preventing electrical leakage and short circuits. Its excellent thermal stability ensures that the cable can operate stably in the normal environment ranging from - 40°C to + 90°C, as well as in short - term high - temperature conditions of up to + 120°C, making it suitable for a variety of complex climate conditions.

Outer Sheath: The outer sheath is made of UV - stabilized, halogen - free thermoplastic elastomer (TPE). The sheath of the 6mm twin - core cable can effectively resist long - term UV radiation, preventing aging and cracking. At the same time, when used outdoors, it can withstand the abrasion of rain, wind, and sand, as well as the erosion of mild chemical substances, comprehensively protecting the internal structure of the cable and extending its service life.

II. Strict Manufacturing Processes

The production of 6mm twin core PV cables follows strict procedures. Every step, from the extrusion of the insulation and sheath layers to the stranding and assembly of the conductors, is carefully controlled. With the help of high - precision equipment, the thickness of the insulation and sheath of the 6mm core is ensured to be uniform, and the conductors are stranded tightly and consistently, ensuring the stable performance of the cable and reducing the risk of failures caused by manufacturing defects.

III. Outstanding Performance Features

3.1 High Current - Carrying Capacity

The 6mm² core twin core PV cable can carry a current of 41A per core, and the total current - carrying capacity of the two cores can reach 82A at 90°C. This enables it to easily meet the power transmission requirements of medium - sized commercial buildings or large residential rooftop photovoltaic systems. When connecting multiple solar panels, it effectively avoids overheating problems caused by excessive current, ensuring the stable transmission of electricity to the inverter or the power grid.

3.2 Long Service Life

With high - quality materials and precise manufacturing, the 6mm twin core PV cable has a service life of up to 20 - 30 years. During long - term outdoor use, it can continuously resist environmental erosion, mechanical stress, and electrical losses, reducing the replacement frequency and significantly lowering maintenance costs, providing strong support for the long - term stable operation of photovoltaic systems.

3.3 Flexible and Easy to Install

Despite its robust structure, the 6mm twin - core cable still has good flexibility. The combination of stranded conductors and elastic insulation and sheath materials makes it easy to route in narrow rooftop spaces and complex pipes. The twin - core structure integrates the positive and negative conductors in the same outer sheath. During installation, there is no need to handle two separate single - core cables, saving about 30% of the installation time and reducing the risk of incorrect polarity connections.

IV. Strict Quality Certifications

The 6mm twin core PV cable has passed a number of authoritative certifications, including TÜV EN 50618, IEC 62930, UL 4703, and RoHS. The TÜV EN 50618 certification ensures that it meets the specific requirements of photovoltaic systems in terms of electrical safety, mechanical strength, and environmental durability, providing quality assurance for installers, system owners, and regulatory authorities and proving its suitability for various solar energy projects.

V. Wide Range of Application Scenarios

5.1 Large Residential Solar Systems

For large residential rooftop photovoltaic systems equipped with multiple solar panels and with a power of 8 - 15kW, the 6mm twin core PV cable can efficiently connect all components. Its flexible routing characteristics can adapt to the complex structure of the roof, ensuring the stable transmission of electricity from the solar panels to household electrical equipment or energy storage systems.

5.2 Commercial Building PV Projects

It performs excellently in the PV installations of commercial buildings such as shopping malls and office buildings. The PV systems in these places have high power and a large number of components. The 6mm twin - core cable can reliably transmit the large amount of electricity generated by the solar panels to the building's power grid with its high current - carrying capacity and long - distance transmission advantages, helping commercial buildings achieve green energy - saving goals.

5.3 Small - Scale Solar Power Plants

In small - scale ground - mounted solar power plants, the 6mm twin core PV cable can be used to connect solar panel arrays in different areas, realizing power collection and transmission. Its durability and stability can ensure the long - term stable power generation of the power plant in the changeable outdoor environment.
