URSUS® MT KN PLUS
The URSUS® MT KN PLUS represents a paradigm shift in high-performance reeling cable engineering. Designed for applications operating at 240 metres per minute—more than 3× faster than standard TBM or mining hoist cables—this cable combines extreme mechanical durability with unprecedented lightweight performance, enabled by Kevlar®-reinforced core construction.
Applications requiring ultra-high-speed reeling (deep-sea drilling riser deployment, offshore wind turbine installation vessels, ultra-fast tunnelling machines, and extreme industrial winches) have long sacrificed either speed capability or mechanical reliability. Conventional cables break under the torsional and tensile stresses of 240 m/min operation. The URSUS MT KN PLUS eliminates this compromise: it delivers double the tensile strength of standard cables while reducing overall weight and diameter, enabling faster deployment cycles, larger cable payloads per reel, and dramatically improved operational efficiency.
![VDE 0250 rubber cables are required to comply with IEC 60332-1 flame retardancy testing, which evaluates the vertical flame propagation characteristics of single insulated wires and cables under fire conditions. This standard establishes that the cable must self-extinguish after flame removal and the charred zone must not extend within 50mm of the upper mounting clamp. Most VDE 0250 rubber cables constructed with flame-retardant materials such as chloroprene rubber (CR/Neoprene) or compounds with flame-retardant additives are designed to pass this critical fire safety test.[1][2] VDE 0250橡胶电缆必须符合IEC 60332-1阻燃测试要求，该测试评估单根绝缘电线电缆在火灾条件下的垂直火焰蔓延特性。该标准规定电缆在移除火焰后必须自熄，且碳化区域不得延伸至上固定夹具50mm范围内。大多数采用阻燃材料（如氯丁橡胶或添加阻燃剂的化合物）制造的VDE 0250橡胶电缆均设计为通过此关键防火安全测试。](https://feichuncables.com/blog/wp-content/uploads/image-576.avif "What is the Requirement for Flame Retardancy (IEC 60332-1) in Standard VDE 0250 Rubber Cables? 3")
