Problems solved by technology

[0003] Most of the outer protective materials commonly used for cables are resin materials, and ordinary cables are often used for laying circuits outdoors. However, due to the extreme climate in some areas, such as the winter climate in Northeast China and its severe cold, the mechanical properties of cable materials are seriously reduced in cold conditions. It is easy to cause problems such as embrittlement and fracture, which will affect the service life. Therefore, improving the cold resistance of cable materials is an important research direction at this stage.

Description

technical field [0001] The invention relates to the technical field of cable processing, in particular to a long-acting cold-resistant cable material and a preparation method thereof. Background technique [0002] Cable electric cable; power cable, usually a rope-like cable twisted by several or several groups of wires, at least two in each group, each group of wires is insulated from each other, and often twisted around a center, the whole The outside is covered with a highly insulating covering. [0003] Most of the outer protective materials commonly used for cables are resin materials, and ordinary cables are often used for laying circuits outdoors. However, due to the extreme climate in some areas, such as the winter climate in Northeast China and its severe cold, the mechanical properties of cable materials are seriously reduced in cold conditions. It is easy to cause problems such as embrittlement and fracture, which will affect the service life. Therefore, improving...
