EN photovoltaic silane cross-linked low smoke zero halogen sheath material TGWH5100 EN sheath
This product is mainly applied to the sheath layer of photovoltaic cables in accordance with EN50618 standard. The product can meet the requirements of high-speed extrusion production. The product adopts the silane cross-linking process, featuring excellent extrusion fluidity and resistance to pre-cross-linking. Cross-linking can be achieved through natural placement for 3 to 5 days, or it can be quickly cross-linked by steam or water boiling, significantly reducing the time for subsequent processes after the line is formed.
