UL photovoltaic silane cross-linked low smoke zero halogen sheath material TGWH5200 UL sheath

This product is mainly applied to the sheath layer of UL4703 standard photovoltaic cables and, in combination with UL insulation, meets the VW-1 combustion grade. 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.
