Abstract

The article discusses the issue of increasing the dielectric strength of solid insulation of conduits used in various areas of the electric power industry, chemical and metallurgical industries, as well as in the agro-industrial complex. For a conductor with a voltage class of 6 (10) kV with a specially developed new type of insulating compound, electric strength tests were carried out with a full lightning impulse and one-minute power frequency voltage. As a result of the tests carried out, the functionality of the improved design and the new type of insulation was confirmed.
