The dielectric constant of the 3GI3 elastomeric insulation used in (N)3GHSSYCY 3x150+3x25/3 cable is approximately 6.2 to 6.8 at standard reference frequency of 1 kHz, with typical measured value around 6.5 for new cable material. The insulation breakdown voltage (also called dielectric strength or withstand voltage) exceeds 30 kV when measured under controlled laboratory conditions on fresh cable samples with 8 mm insulation thickness, typically achieving 32–38 kV before electrical breakdown occurs.
