Abstract
A dielectric element (2) for a high-voltage insulator (1) of very great traction strength, greater than 700 kN, of the type comprising a toughened glass body of revolution about a longitudinal axis (A) having a hollow head (6) extended by a ribbed shed (7). It has a profile that defines a creepage distance lying in the range 550 mm to 800 mm for an outside diameter (DJ) of the shed (7) that lies in the range 380 mm to 450 mm and a pitch (P) that lies in the range 260 mm to 290 mm, said dielectric element also presenting weight lying in the range 10 kg to 13 kg.
