Experimental Study of the Effect of Ozone and Low Temperatures on the Insulation of Electrical Materials

Ozone and low temperatures influence on isolation of electrical materials are considered. Combination of low temperature food storage with the electron-ion technology (including ozone) gives an ability to solve the problems of products spoilage minimization and reduction of energy consumption. Real objects have storage temperatures from -24°C till +24°С. Ozone is used at the same. Power, electrical and informational communication lines were used. The object of the research was samples of electrical products. Usually they are used in low temperature storage chambers. Combined effect of low temperatures, ozone different densities, mechanical loading on isolation of communicational lines are analyzed. Most samples after exposure of low temperatures and high ozone densities stand the test. That’s why it is possible to use them in practice. Only KG (H07RN-F) didn’t pass the test. The isolation of several samples, such as VVG (NYY-O), VVGng (NYY-J), PWC (H05VV-F) and PW-3, cracked at cooling temperatures -18°С and -24°С. In real use these samples are not so loaded. So, it can be considered, that in conditions of long use, electrical materials are usable (low temperatures and ozone densities till 40 g/m 3 are allowed). The results allow making a conclusion that most modern industrial low temperature storage chambers let use electron-ion technologies.
