Silane Self-crosslinking LSZH-HFFR Polyolefin Cable Material For Photovoltaic Cables

Silane self-crosslinking halogen-free, low-smoke, flame-retardant polyolefin cable materials for photovoltaic cables comply with ROHS, REZCH and other relevant environmental protection requirements. The material properties meet the requirements of EN50618-2014 standards and are suitable for the production of insulation and sheath layers of solar photovoltaic cables.

1. Mixing: Before using the product, mix components A and B evenly and add them to the hopper. After opening the package, it is recommended to use up the materials within 2 hours. It is forbidden to dry the materials. Components A and B should be strictly prevented from bringing in external moisture during the mixing process.

2. It is recommended to use ordinary single-thread screws for insulation with a compression ratio of 2.5-3. It is recommended to use low-smoke halogen-free special screws for sheaths with a compression ratio of 1.5±0.2.

3. Pay-off speed: Increase the pay-off speed as much as possible without affecting the surface finish.

4. Cross-linking process: After the wire is formed, it can be cross-linked naturally or in a water bath (steam). Natural cross-linking: The temperature is above 25°C, and the cross-linking can be completed within one week. Use water bath or steam cross-linking. To prevent cable adhesion, the water bath (steam) temperature is controlled at 60-70°C, and the cross-linking can be completed in about 4 hours. The above cross-linking time is based on the insulation thickness ≤1mm as an example. If the thickness exceeds this, the specific cross-linking time should be adjusted according to the product thickness and the degree of cross-linking to meet the cable performance index requirements. When testing the full performance of the cable, it is recommended to use a water bath (steam) at 60°C and a cooking time of more than 8 hours to ensure that the material is fully cross-linked.
