Problems solved by technology

[0002] Generally, the outer layer of core insulation of multi-core cables is protected by a sheath layer, so the environmental resistance requirements are low, but due to the secondary vulcanization process of the extruded sheath, the plastic material is extruded through a low-temperature extruder, and the secondary vulcanization There is no special impact on the process, but the insulation performance of plastic is poor, it is easy to age, and the mechanical performance and environmental resistance are far from those of rubber. In some occasions with high requirements for use and safety, it is generally not recommended to use plastic materials, such as rail transit vehicle cables, etc.
Although the rubber material has excellent performance, the insulating rubber is easy to expand and deform during the secondary vulcanization, and the contact extrusion part of the wire core is easy to become thin, which seriously affects the insulation performance.
