2*10 square photovoltaic cable

2 × 10mm ² photovoltaic cable is a one-to-one cable designed specifically for DC transmission of solar photovoltaic systems. The core models are mostly PV1-F 2 × 10mm ² or H1Z2Z2-K 2 × 10mm ², which comply with the IEC 62930/EN 50618 universal standard and TUV Rheinland 2 PfG1169 certification requirements. It is mainly used for DC power connection between core equipment such as photovoltaic modules, combiner boxes, inverters, etc., with a rated voltage of up to DC 1.5kV, and can fully adapt to the effects of high-power photovoltaic projects and meet the requirements of safe transmission.

1、 Core Structure and Materials

The cable adopts a highly adaptable structural design and excellent materials to protect long-term stable operation: the conductor part is made of tin plated annealed copper material, using IEC 60228 Class 5 soft conductor standard and multi strand fine twisting process, which not only has excellent conductivity, but also has good flexibility. The outer tin plating layer can effectively prevent copper conductor oxidation and corrosion, extending the service life of the cable; The insulation layer is made of irradiated cross-linked polyolefin (XLPO/XLPE) material. After electron beam cross-linking treatment, the insulation performance is greatly improved, and it can effectively resist high voltage and high temperature (based on actual reports), rejecting the risk of current breakdown; The sheath layer is also made of low smoke halogen-free irradiated cross-linked polyolefin material, forming dual insulation protection, with multiple characteristics such as flame retardancy, UV resistance, oil resistance, ozone resistance, and wear resistance (based on actual reports), which can directly adapt to complex and harsh outdoor environments; The overall structure adopts a dual core parallel flat structure, with an isolation strip added in the middle. The positive and negative poles are usually distinguished by red and black colors for easy construction identification, saving wiring space and improving installation convenience.

2、 Key technical parameters

The core technical parameters of this cable model are suitable for the long-term operation requirements of photovoltaic systems: the rated voltage can reach DC 1.5kV (AC adaptation 0.6/1kV), and the system voltage has sufficient safety margin; The working temperature range covers -40 ℃ to+90 ℃, and can withstand high temperatures of up to 120 ℃ for a short period of time. It can adapt to various extreme weather environments such as extreme cold and heat; Under a standard environment of 25 ℃, the continuous current carrying capacity should not be less than 70A. The low resistance design can effectively reduce line losses during transmission; At 20 ℃, the conductor resistance is ≤ 1.95 Ω/km, the conductivity is excellent, the insulation resistance is ≥ 489M Ω· km, the insulation is excellent, and it can withstand a withstand voltage test of 6500V/5min without any breakdown hazards; The overall outer diameter of the cable is about 16.1mm (flat structure), with a compact volume and flexible wiring; The service life is not less than 25 years, which can be well matched with the overall service life of the photovoltaic system, and does not require frequent replacement and maintenance.

3、 Core performance advantages

1. Low consumption effect: Designed with a 10mm ² large cross-sectional conductor, the resistance value is relatively low, and the line loss during transmission is small, which can effectively improve the overall power generation of the photovoltaic system and reduce the long-term operating costs of the project; 2. Extreme environment adaptation: It has excellent resistance to high and low temperatures, UV rays, aging, and chemical corrosion, and can be exposed to harsh outdoor environments such as sandstorms, salt spray, and severe temperature differences for a long time without the need for additional protective facilities; 3. Anran Environmental Protection: Made of low smoke, halogen-free, and flame-retardant materials, it does not produce stable smoke in the event of a fire. The double insulation structure can effectively prevent the risk of electrical leakage. Anran provides protection and complies with RoHS environmental protection requirements, resulting in green pollution; 4. Easy installation: The cable has strong flexibility, small bending radius, and can adapt to complex path wiring. The dual core dual color design can reduce wiring errors and greatly improve construction efficiency; 5. Long life and stability: The optimized combination of irradiation cross-linked material and tin plated copper conductor has aging performance effect, which can protect stable operation for more than 25 years and reduce maintenance costs in the later stage.

4、 Applicable scenarios

This cable is suitable for various photovoltaic project scenarios, especially for high-power transmission needs, including large-scale ground photovoltaic power stations, fishery photovoltaic complementary power stations, agricultural photovoltaic complementary power stations, and other projects where components are connected in series or parallel, and DC connection scenarios from combiner boxes to inverters; Industrial and commercial distributed photovoltaic projects, such as the transmission of photovoltaic systems on factory roofs and commercial building roofs; High power household photovoltaic systems (over 10kW) can effectively reduce voltage drops during long-distance transmission and improve the efficiency of household photovoltaic power generation; It is also suitable for photovoltaic projects in extreme climate areas such as deserts, plateaus, and coastal regions, and can effectively resist harsh conditions such as wind erosion, salt spray corrosion, and large temperature differences between day and night.

5、 Selection and installation suggestions

In terms of selection, it is necessary to comprehensively consider the power, voltage level, and transmission distance of the photovoltaic system. A 10mm ² cross-sectional cable is more suitable for high-power photovoltaic systems with a transmission distance of 50-100 meters, which can achieve excellent results and avoid excessive voltage drop affecting power generation efficiency. During the installation process, the following specifications should be followed: avoid excessive bending during laying, and the bending radius of the cable should not be less than 10 times the outer diameter of the cable; Outdoor installation does not require additional conduit and can be directly exposed for installation, but sharp objects should be avoided from scratching the protective layer; When connecting cables, a one-to-one photovoltaic connector should be used to confirm that the joint is waterproof (based on actual reports) and moisture-proof (based on actual reports). Insulation protection treatment should be done after connection. In terms of maintenance, it is recommended to regularly inspect the appearance of the cables and focus on checking the joints. If problems such as damaged sheaths or loose joints are found, they should be replaced and dealt with in a timely manner to protect the safe and stable operation of the photovoltaic system.

summary

The 2 × 10mm ² photovoltaic cable has the core advantages of high current carrying capacity, low loss, long service life, and strong environmental adaptability. The dual core flat structure simplifies the construction process, and the low smoke and halogen-free material balances safety and environmental protection. Its 25 year service life can be synchronized with the photovoltaic system, providing stable and excellent DC power transmission solutions for various photovoltaic projects, and helping to transform and utilize green energy effects.
