Frequently Asked Questions & Technical Guidance

What distinguishes URSUS-FEICHUN cables from standard industrial power cables?
URSUS-FEICHUN cables incorporate specialized anti-twisting polyester braid technology and dual-layer 5GM5 rubber sheathing. This engineering approach delivers superior resistance to continuous flexing, torsional stress, and mechanical deformation compared to conventional industrial cables. The tinned copper conductors and 3GI3 insulation compound provide enhanced electrical performance in harsh environmental conditions.
How does the maximum working speed of 180 m/min benefit crane operations?
The 180 m/min specification enables rapid load positioning in high-throughput port operations and container handling facilities. This speed capability reduces cycle times while maintaining cable integrity, directly impacting operational efficiency in time-critical industrial applications such as ship-to-shore crane operations and automated container terminals.
What is the significance of the ±50°/m torsional stress rating?
The ±50°/m torsional stress specification indicates the cable’s ability to withstand rotational forces during reeling operations. This parameter is crucial for applications involving continuous winding and unwinding, such as cable drums on rotating cranes or mobile equipment. The anti-twisting element prevents conductor displacement and maintains electrical continuity under extreme rotational stress.
How do environmental resistance properties benefit marine applications?
The combination of oil resistance (IEC 60811-404), ozone resistance (IEC 60811-403), and UV resistance (ISO 4892-2) makes URSUS-FEICHUN cables ideal for marine environments. These properties prevent degradation from salt spray, hydraulic fluids, and intense sunlight exposure common in port facilities, shipyards, and offshore installations.
What installation considerations apply for extreme temperature environments?
For mobile applications down to -30°C, standard URSUS-FEICHUN cables maintain flexibility and electrical performance. For static installations requiring operation to -50°C, specific installation procedures ensure optimal performance. For environments below -40°C in mobile applications, the URSUS VS K variant provides enhanced cold weather performance.
How does the laying-up specification affect installation requirements?
The ≤8 times laying-up cores diameter specification defines minimum bend radius requirements during installation. This parameter ensures conductor integrity and prevents insulation damage during cable routing through drum systems, cable trays, and confined spaces in industrial installations.
