Irradiation Crosslinkable LSZH Insulation Compound for Photovotaic Cable
This material is used for halogen-free flame retardant(irradiation crosslinkable) wire and cable insulation material. It is made of high quality resin, flame retardant, antioxidant agent and cross-linking agent by mixing granulation. None-halogen property makes the materials non-toxic when burning; it has excellent flame retardancy, good physical and mechanical properties and processing performance; Heat resistance level is 125℃, can pass the VD-1 combustion test.
Standard: EN50618 & TUV1169
Application: Photovoltaic system/solar panel; Wire and cable; Control wire and cable; Railway wire and cable
