HJ0602 Semi-conductive Insulation Shielding Compound For MV Power Cables [Easy Strippable Grade]

Low peeling force strippable semi-conductive insulation shielding material is an easy-to-peel cross-linked semi-conductive insulation shielding material designed for medium-voltage power cables. It is suitable for extruded insulated cable systems with a rated voltage not exceeding 36kV. The biggest highlight of this product is its low peeling force (≤20N/cm), which can easily separate the insulation layer from the shielding layer, greatly improving the construction convenience and on-site maintenance efficiency. At the same time, it has good electrical properties, processing performance and stable cross-linking characteristics, and is one of the high-quality solutions for medium-voltage cable insulation shielding layers.
It has excellent melt flow performance and is suitable for various dry vulcanization extrusion equipment. Under high-speed extrusion conditions, a smooth, uniform and dense extrusion layer can still be obtained, ensuring the appearance and performance of the finished cable.
