Research and Production of Transformers with Heat Resistant Insulating Materials

Abstract

At the present stage of development of manufacturing transformers in Kazakhstan and questions about the use of insulating materials for dry-type transformers. The urgency of this problem is due to provide electrical insulation elements in conductive electrical devices between different potentials. By increasing the potential difference (voltage) occurs in isolation critical voltage, where the insulation breaks. This is called the breakdown voltage and insulation property maintaining a certain tension for a long time called the dielectric strength. The aim of the work is to analyze the insulation materials used in transformers, their types and properties.
