EN-Standard PV Cable Compound

YHS62027(EN)-125

Irradiation cross-linked EN photovoltaic cable material (YHS62027(EN)-125) adopts special polyolefin and heat-resistant elastomer as the base material, added with flame retardants, smoke suppressants, cross-linking sensitizers, antioxidants and processing aids, then mixed, plasticized and pelletized. It possesses excellent physical and mechanical properties, electrical properties, flame retardancy and processability, together with good low-temperature resistance, high-temperature resistance, ozone resistance and solvent resistance. It is suitable for photovoltaic cable insulation and complies with **EN 50618**, with low smoke emission performance.

Recommended

Extrusion Process

When the storage environment is wet or the production surface is required to be high, the particles can be dried in a hot air hopper at 70℃ for 1-2 hours.

It is recommended to use a low compression ratio screw extrusion with a compression ratio of 1.2-2.0:1.Before extrusion, the screw should be cleaned to ensure the cleanliness of the product. It is recommended to use 80 mesh or 100 mesh filter screen to avoid impurities in the extrusion process, and to ensure the melt pressure to obtain a good appearance and material density.As the difference between the actual temperature of the melt and the indicated value of the temperature control table varies with the type of extruder, the user is requested to select the appropriate temperature according to the specific situation of the extruder used.The following temperatures can be used as reference for start-up and commissioning:

Position	Cylinder I	Cylinder II	Cylinder III	Cylinder IV	Cylinder V	Head and mold
Temperature	120±5	150±5	160±5	165±5	170±5	175±5
