Introduction to the basic knowledge of conductor shielding layer and metal shielding layer
Conductor shielding layer (also called inner shielding layer, inner semi-conductive layer) The conductor shielding layer is a non-metallic layer extruded on the cable conductor, which is equipotential with the conductor and has a volume resistivity of 100~1000Ω•m. Equipotential with the conduct...Read more -
