Medium voltage cables and their accessories must pass 100% exit checks in dielectric strength and partial discharge measurements.
During type tests, they must also undergo several controls such as electrical aging, rising to breakdown by voltage levels, endurance tests during which the dielectric stresses are applied simultaneously with the heating / cooling cycles.
In addition to our high voltage and high current sources, we propose the design and the supply of safety cages to ensure the protection of persons.
