Electrical Insulation and Dielectric Materials

Electrical insulation and dielectric materials includes various forms of materials that surround and protect electrical conductors and prevent unwanted current flow, leakage or crosstalk. Electrical specifications include electrical resistivity, dielectric strength, and dielectric constant. Resistivity is the longitudinal electrical resistance (ohm-cm) of a uniform sample of unit length and unit cross-sectional area. Dielectric strength is the maximum voltage field that electrical insulation and dielectric materials can withstand before electrical breakdown occurs.
