An electrical cable () is provided having () a conductive element (), a first layer () having polyimide (PI) surrounding said conductive element (), a second fluorinated layer () having at least one fluorinated compound, surrounding the first layer, and optionally at least one fluorinated semiconductor layer having at least one fluorinated compound, where the total thickness of the assembly of fluorinated layers is at least 0.4 mm.

Electrical cable that is resistant to partial discharges

An electrical cable having an elongate electrically conductive element () and at least one electrically insulating fluoropolymer layer () surrounding the electrically conductive element (). The electrical cable is exempt from polyimide-containing layer between the electrically conductive element and the electrically insulating fluoropolymer layer.

Electrical cable resistant to partial discharges

An electric cable includes an electrical conductor surrounded by a first layer of mica tape made up of mica particles deposited by means of a polymer binder on a backing, a second layer of a polyimide tape, and a third layer of a polytetrafluoroethylene tape, where the first layer is subjected to heat treatment at a temperature of at least 400&#xb0; C. and the ratio R of the weight per unit length of PTFE over the sum of the weights per unit length of the polymer binder and of the polyimide is such that R is greater than or equal to 2 when the section of the electrical conductor is no greater than 0.2 mm, R is greater than or equal to 4 when the section of the electrical conductor is strictly greater than 0.2 mmand strictly less than 0.6 mm, R is greater than or equal to 6 when the section of the electrical conductor is equal to 0.6 mm, and R is greater than or equal to 12 when the section of the electrical conductor is strictly greater than 0.6 mm.
