Analysis Test Results of KZ8A and KZ4AT Series Electric Locomotives Planned for Operation on Azerbaijani Railways

The article reflects the technical characteristics and analysis of the test results Kazakhstani freight and passenger electric locomotives of a new generation of the K8ZA and KZ4AT series, which are developed according to the technology of a French company and are produced in Kazakhstan. An overview of the production and operation of electric locomotives this class abroad, including in Europe, is given. Certification and acceptance tests electric locomotives were carried out, which include vibroacoustic tests, sanitary and environmental tests, as well as checking the level of electromagnetic radiation. Tests of the electric locomotive were completed under the conditions of the climatic chamber, which confirmed the operability outdoor equipment in the range from -50 to $+45^{\circ} \mathrm{C}$. A comparative analysis of the characteristics first Kazakh electric locomotives of the KZ8A and KZ4AT series shows that these locomotives are very economical in terms their life cycle, have higher traction characteristics, increased overhaul runs in comparison with electric locomotives this class. On the basis of the Kazakh electric locomotive of the KZ8A series, a modification of the AZ8A freight electric locomotive for Azerbaijani railways was developed.
