用作起重机、升降机及干湿环境各类电气装置的连接与控制电缆,尤其适合矿山等重载拖曳工况。设计强调外护套长期耐磨不破损;内置航空钢丝与抗拉纤维等加强件,抗拉强度高、避免断芯;强化抗扭结构,适应巷道内长距离拖拽与频繁转弯而不开裂;并具备良好的防水与耐腐蚀能力。导体为绞合无氧铜,绝缘PVC,芯数2~60芯;内护套TPU/NBR,外护套PUR(颜色可定制)。固定敷设-40~+90℃,移动敷设-30~+90℃,最小弯曲半径7.5D,额定电压600/1000V。
Application：As connecting and control cables for lifts or cranes, also used for various kinds of electric installation in dry or wet environments.
Design requirements:
√ High wear resistance: the cable sheath must be able to withstand the ore friction for a long time without damage.
√ High tensile strength: in mining, the use length of cable is relatively long, and the ground friction is very large, which requires the cable to have a strong tensile strength to avoid core broken.
√ Torsional resistance: the cable needs long-distance drag in the underground roadway, and often turns in the roadway, which is bound to cause the torsion of the cable, the strong torsion resistance avoids the sheath crack.
√ Water resistance and corrosion resistance: in underground mining, there may be water or corrosive liquid, which requires the cable to have enough waterproof and corrosion resistance.
