Technological Violations on Overhead Lines with Voltage of 10 Kv

10 kV overhead power networks are the longest distribution networks. About 60-70% of power interruptions occur in these networks. Based on a general analysis of technological violations associated with emergencies, the article presents the statistics for five years on the breakage of phase wires of overhead lines. A break is one of the most dangerous injuries that pose a serious danger to people and animals as well as lead to fire hazardous situations. The causes of wire breakage of 10 kV overhead lines, the frequency of their occurrence are considered in detail. The influence of climatic (season of the year, adverse weather conditions, thunderstorms, ice rains, etc.) and other (non-compliance with operating requirements, deterioration of materials and structures, unauthorized actions, etc.) factors on the possibility of wire breaks is shown. The characteristic accidents with people caused by touching broken wires are described.
