RHEYFIRM® (RS) 与 RHEYFIRM® (RTS) 对比：何时选择 RHEYFIRM® KE 凯夫拉 (N)TSKCGECWÖU 超长垂直行程电缆
1. Introduction to RHEYFIRM® Cable Series 概述
The RHEYFIRM® cable series represents the industry benchmark for flexible reeling and trailing cables designed for extreme mechanical stress applications. These cables are engineered to DIN VDE 0250-813 standards, which remain the globally recognized specification for tough rubber-sheathed flexible reeling cables used in cranes, mining equipment, and material handling machinery.
When vertical travel distances exceed conventional limits, particularly in deep shaft mining, high-rise elevator systems, and ship-to-shore crane applications, the selection between standard steel-reinforced cables and Kevlar (aramid fiber) reinforced alternatives becomes critical for operational safety and longevity.

4. RHEYFIRM® KE Kevlar (N)TSKCGECWÖU: Ultra-Long Vertical Travel Solution 超长垂直行程解决方案
For applications requiring vertical travel distances exceeding 300 meters, conventional steel-reinforced cables face significant limitations due to self-weight loading. The RHEYFIRM® KE series incorporates Kevlar (aramid fiber) reinforcement to address these challenges.
4.1 Kevlar Reinforcement Advantages 凯夫拉加强优势
Kevlar Aramid Fiber Properties 凯夫拉芳纶纤维特性
According to DuPont technical documentation, Kevlar aramid fiber provides strength comparable to steel while maintaining only 14-15% of the weight. This characteristic makes Kevlar-reinforced cables the optimal choice for ultra-long vertical applications where cable self-weight becomes a limiting factor.

The engineering decision between steel and Kevlar reinforcement depends on the specific vertical travel requirements and operating conditions. For deep shaft mining hoists exceeding 500 meters, Kevlar reinforcement provides significant advantages in reducing total suspended cable weight while maintaining required tensile strength.

6. Application Selection Guidelines 应用选型指南
Deep Shaft Mining Hoists 深井矿山提升机
Recommended 推荐: RHEYFIRM® KE (N)TSKCGECWÖU
Vertical travel >300m requires Kevlar reinforcement to manage cable self-weight. The non-conductive nature of aramid fibers provides additional safety in potentially explosive atmospheres.
Ship-to-Shore Cranes (STS) 岸桥起重机
Recommended 推荐: RHEYFIRM® (RTS) (N)TSCGEWTOEUS
High reeling speeds up to 190 m/min with multi-plane deflection capability. Integrated optical fiber options available for data transmission.
Open-Pit Mining Excavators 露天矿挖掘机
Recommended 推荐: RHEYFIRM® (RTS) R-(N)TSCGEWTOEUS
Level-wind reel applications with high torsional stress. Steel reinforcement provides crush resistance for drum winding.
High-Rise Elevator Systems 高层电梯系统
Recommended 推荐: Kevlar-core traveling cable
Travel heights >160m benefit from Kevlar reinforcement. Reduced cable weight enables smaller pulleys and lower energy consumption.
