When a Type 8 DWA cable hangs vertically in a mine shaft carrying its full self-weight (typically 10–20 kg per meter), the cable must be secured with cleats at regular intervals to prevent movement, vibration, and sway. However, the traditional approach of simply gripping the cable's outer sheath with mechanical cleats creates a dangerous paradox: sufficient grip force to prevent slip also crushes the delicate insulation layers beneath the sheath. 当Type 8 DWA电缆在矿井竖井中垂直悬挂并承载其全部自重(通常每米10-20公斤)时，必须定期用线夹对电缆进行固定，以防止移动、振动和摇摆。然而，用机械线夹简单地夹紧电缆外护套的传统方法造成了危险的悖论：足以防止滑脱的夹紧力也会压坏外护套下的精细绝缘层。 The Engineering Dilemma: (1) Under-tightened cleats → cable slips under load, creating movement and mechanical fatigue of insulation, eventually leading to internal short circuits. (2) Over-tightened cleats → radial pressure crushes insulation, creating voids and micro-fractures that initiate partial discharge and electrical breakdown.

Deep underground mining operations depend on sophisticated systems for moving workers, equipment, and materials between the surface and mining zones that may be hundreds of meters below ground level. One of the most critical systems in these operations is the basket or cage suspension system that safely lowers and raises workers and cargo through vertical mine shafts. These systems rely on flexible (N)SHTÖU cables to deliver electrical power for lighting, ventilation, and communication equipment in the basket, while the mechanical support for the basket itself is provided by separate wire ropes or cables. The electrical cables must be suspended alongside the main support ropes, and this suspension relies on devices called mesh grips — specialized clamping devices that gently but firmly grip the cable without damaging its insulation or internal conductors.
