Technical Advantages 技术优势
The PROTOLON cable system incorporates several advanced engineering features that distinguish it from conventional mining cables. According to research conducted on DIN VDE 0250 standard cables, these design elements significantly enhance performance and reliability in demanding applications.
High Flexibility 高柔韧性
The use of very finely stranded copper conductors (Class FS) combined with high-quality EPR insulation provides exceptional flexibility, enabling the cable to withstand continuous bending cycles on reeling drums without conductor fatigue or insulation cracking.
Superior Tensile Strength 卓越抗拉强度
Polyester braiding reinforcement provides tensile strength up to 30 N/mm², essential for supporting the cable’s own weight across spans that can exceed 100 meters in large mining equipment installations.
Enhanced Environmental Protection 增强环境保护
The polychloroprene (PCP) outer sheath delivers outstanding resistance to oil, ozone, UV radiation, and seawater, ensuring long service life in harsh mining environments where exposure to industrial fluids and extreme weather is common.
Optimized Electrical Performance 优化电气性能
The semi-conductive screening layers ensure uniform electric field distribution, reducing the risk of partial discharge and extending insulation life. Low capacitance values minimize charging currents and improve power factor.
