As for low-voltage wires and cables, they are mainly divided into two categories according to their purpose: construction wires and electrical equipment wires. In the construction wire, it was natural rubber insulated woven asphalt coated wire as early as the 1960s. Since the 1970s, it has been completely replaced by PVC plastic wires. The situation in electrical equipment lines is similar to that in construction lines, which was originally dominated by natural rubber, but was largely replaced by PVC cables in the 1970s. This situation is both unscientific and unreasonable in terms of the cable industry and user choices. Nowadays, various electrical equipment cables, especially the connecting cables required for booming household appliances, should change the current situation of being dominated by PVC plastic and replace them with rubber cables. Because rubber cables have unique advantages such as softness, good hand feel, no fear of heat, and no melting, they are incomparable to plastic cables. Due to its many advantages that synthetic rubber does not have, CPE can be widely used in the manufacturing of household electrical cords and other flexible cables for electrical equipment. CPE has comprehensive technical properties, such as excellent flame retardancy and high oil resistance, physical and mechanical properties (i.e. mechanical properties), good heat aging resistance, ozone resistance, climate resistance, good electrical properties, and good processing performance. It can be used in general rubber processing equipment, and the rubber material is not prone to scorching. CPE raw materials will not deteriorate after several years of storage, Rubber materials with vulcanizing agents can be stored for 1-2 years without deterioration under better storage conditions.
In summary, the application of CPE in the online cable industry, that is, replacing CR with CPE, is a trend in the online cable industry. This not only alleviates the supply-demand contradiction of CR, significantly reduces the cost of cable products, improves the economic benefits of the cable industry, but also has profound significance in improving the grade of cable products and achieving diversification of cable varieties.
