    Product Introduction

    This product complies with relevant environmental requirements such as RoHS and REACH. The material performance meets the standards of EN 50618-2014, TUV 2PfG 1169, and IEC 62930-2017. It is suitable for insulation and sheathing layers in the production of solar photovoltaic cables.

    Model Material A: Material B Usage
    OW-XLPO 90:10 Used for photovoltaic insulation layer.
    OW-XLPO-1 25:10 Used for photovoltaic insulation layer.
    OW-XLPO-2 90:10 Used for photovoltaic insulation or insulation sheathing.
    OW-XLPO(H) 90:10 Used for photovoltaic sheathing layer.
    OW-XLPO(H)-1 90:10 Used for photovoltaic sheathing layer.

    Processing Indicator

    1. Mixing: Before using this product, mix components A and B thoroughly and then add them to the hopper. After opening the material, it is recommended to use it within 2 hours. Do not subject the material to drying treatment. Be vigilant during the mixing process to prevent the introduction of external moisture into components A and B.

    2. It is recommended to use a single-threaded screw with equidistant and varying depths.

    Compression Ratio: OW-XLPO(H)/OW-XLPO/OW-XLPO-2: 1.5±0.2, OW-XLPO-1: 2.0±0.2

    3. Extrusion Temperature:

    Model Zone one Zone two Zone three Zone four Machine Neck Machine Head
    OW-XLPO/OW-XLPO-2/OW-XLPO(H) 100±10℃ 125±10℃ 135±10℃ 135±10℃ 140±10℃ 140±10℃
    OW-XLPO-1 120±10℃ 150±10℃ 180±10℃ 180±10℃ 180±10℃ 180±10℃

    4. Wire Laying Speed: Increase the wire laying speed as much as possible without affecting surface smoothness and performance.

    5. Cross-Linking Process: After stranding, natural or water bath (steam) cross-linking can be performed. For natural cross-linking, it can be completed within a week at temperatures above 25°C. When using a water bath or steam for cross-linking, to prevent cable adhesion, maintain the water bath (steam) temperature at 60-70°C, and cross-linking can be completed in approximately 4 hours. The above-mentioned cross-linking time is provided as an example for insulation thickness ≤ 1mm. If the thickness exceeds this, the specific cross-linking time should be adjusted based on the product's thickness and cross-linking level to meet the cable's performance requirements. Perform a complete performance test, with a water bath (steam) temperature of 60°C and a boiling time of more than 8 hours to ensure thorough material cross-linking.
