In recent years，the environmentally friendly cable material based on polypropylene (PP) exhibits broad application prospects. Due to the difficulty in recycling thermosetting plastics, they can pose significant environmental issues that cannot be ignored. Therefore, recyclable thermoplastic polypropylene material is more in line with the positioning of cable material for high transmission capacity and environmentally friendly power cables while advocating for green environmental protection. This is also one of the future development directions of high-voltage power cable materials.

WANMA MACROMOLECULE insulation and shielding material for 110kV Polypropylene cable can possess the unique advantages of plasticization and recycling, together with excellent insulation and temperature resistance property, which can increase current carrying capacity, simplify processing technology, reduce production costs, and improve production efficiency. It does not require high-temperature vulcanization and cross-linking, and the production process produces less by-products. When using CCV or VCV production lines for processing, it reduces the workload of cleaning vulcanized pipelines. The vulcanized pipelines do not require heating, which can effectively save energy for customers.

Polypropylene material not only provide strong support for the deepening development of WANMA MACROMOLECULE environmentally friendly material, but also provide new momentum for green reform of the cable industry. They will also contribute to the achievement of the goal of "carbon peaking and carbon neutrality".
