Description

technical field [0001] The invention relates to the technical field of cables, in particular to a high-strength oil-resistant power cable. Background technique [0002] Power cables are cables used to transmit and distribute electric energy. They are often used in urban underground power grids, outgoing lines of power stations, internal power supply of industrial and mining enterprises, and underwater transmission lines across rivers and seas. With the development of the economy, the places where power cables need to be used have become diversified, and there are more stringent and diverse requirements for the performance indicators of power cables, such as tensile strength, service temperature, aging resistance, flame retardancy and other indicators. There are strict requirements, and the continuous improvement of the comprehensive performance of power cables is an urgent need for economic and social development. Most of the existing power cables have problems such as low ...
