Abstract. Many insulation systems consist of materials of different nature. In complex electrical equipment, the insulation of which is exposed to high electrical voltages, there are often several such systems at the same time. In order to verify the performance capability of a complex insulation system, electrical tests are carried out in accordance with the standards. In the process of such tests, not enough attention is always paid to the specific features of joint electrical, thermal or other types of aging of materials and to their consequences. This circumstance is the reason for the electrical equipment manufacturers to look for new approaches to the study of the mutual influence of materials, as well as to find modern and less resource-intensive test methods.
This article is devoted to the approbation of the test procedure used to assess the compatibility of the insulating silicone elastomer of the stress cone and the liquid dielectric of the termination, based on the national standards, and used for a long time at the “Izolyator” plant.
Key words: liquid dielectric, oil impregnated-paper bushing, dielectric loss tangent, acid number, purity class, cast silicone composition

Abstract. A high-speed highway in the design encounters many problems, for which it is necessary to find the best ways. One of these problems is the overheating of the wire of the contact network (CN) when passing through the neutral insert with the current collector raised. The authors propose an insulating connection device of the contact network (ICD CN), which will avoid the occurrence of an electric arc, and, consequently, overheating and subsequent failure of the contact wire.
ICD CN is a set of resistances that change towards the end of the section before the neutral insertion. During the study of various methods of forming step resistances, specific values were obtained for each section of the ICD CN, the total length and number of sections of the ICD CN were calculated. A study of the ICD CN was conducted on the burnout of the contact wire due to the ingress of a large current on the resistances of the ICD CN.
The result of the work was a thermal calculation of the conditions for the destruction of the contact wire due to overheating, which made it possible to find a section with maximum heating and maximum temperature change in each section when moving the rolling stock at different speeds: 100 km/h; 200 km/h; 300 km/h; 400 km/h.
Key words: stepped resistances, insulating interface device, contact network, electric arc, overheating of the contact network

THE RESULTS OF THE EVOLUTION OF THE GENERAL PURPOSE INDUSTRIAL PVC PLASTICS MARKET AT THE END OF 2022
O.K. Barashkov, Cand. Sc. (Chemistry), Technical Director of the, Ltd. “Vestplast”
Abstract. The article deals with the current state of the Russian market of general purpose industrial PVC plastics. It is stated that the characteristics of the plastics consumed by the cable plants fail to meet the requirements of GOST 5960–72. The main reason for the situation that is now in evidence is the desire of the cable manufacturers to reduce the production costs. Some specific methods of cost reduction are considered. It is noted that it is necessary to create an effective conformity assessment system as the only barrier excluding the appearance of low-quality products on the market.
Key words: quality, conformity assessment, standards, industrial PVC plastics
