PYJJ-35 semi-conductive crosslinkable insulation screen is a type of insulation material used for XLPE cables up to 35kV. It is designed to provide a semi-conductive layer between the conductor and the insulation, reducing electric stress and preventing electrical breakdown.
The material is crosslinkable, meaning it can be chemically or physically crosslinked to improve its mechanical and electrical properties. This makes it suitable for use in harsh environments where the cable may be exposed to high temperatures, chemicals, and mechanical stress.
PYJJ-35 semi-conductive crosslinkable insulation screen is typically made of a blend of polyethylene and carbon black, which gives it its semi-conductive properties. It is applied as a thin layer over the conductor and is crosslinked along with the insulation during the cable manufacturing process.
