The Relationship Between Dielectric Constant and Insulation Materials of Power Cables
Core Correlation Between Cable Dielectric Constant and Insulation Materials The dielectric constant (relative permittivity, εr) is a fundamental electrical parameter defining an insulation material’s ability to store electrostatic energy in an electric field. For low-voltage (LV) power cables complying with IEC 60502-1, the dielectric constant directly determines cable capacitance, partial discharge performance, and voltage withstand […]
