XLPO Compound
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.
