FIELD: electrical engineering. SUBSTANCE: insulator has cap, fastening section securing it on support, and circular ribs. Novelty is that cap and fastening section are built as integral part and second part is secured on external surface of fastening section in a non-spaced relation to form region of circular ribs. Area on surface of first part contacting the carrying member or the current- carrying hardware is connected to surface of second part through current- conducting jumper. First part is made of polymers of high-strength thermoplastic material class, mainly fiber-filled thermoplastic materials such as fiber-filled polybutylene terephthalate and second part is produced from polymers of tracking-resistant class such as silicone resin. EFFECT: enhanced reliability, reduced material and labor consumption. 2 cl, 3 dwg
