Which type of core is used in wire ropes that have higher temperature ratings?

The choice of using a steel core in wire ropes that have higher temperature ratings is based on the material's ability to withstand extreme conditions. Steel cores are designed to provide enhanced strength and stability under high temperatures, which is critical in applications where heat exposure is a factor. Unlike fiber cores, which can degrade or lose their structural integrity when exposed to elevated temperatures, steel cores maintain their properties and do not suffer from thermal degradation.

Additionally, steel cores contribute to the overall load-bearing capacity of the wire rope, making them particularly suitable for heavy-duty applications that require both heat resistance and strength. The robustness of steel as a core material allows it to perform effectively in environments that involve significant temperature fluctuations, ensuring safety and reliability.

Other core types, such as plastic or metal cores, are less common in high-temperature situations primarily due to their lower resilience compared to steel. Plastic cores might not provide the necessary strength, while other metal options may not exhibit the thermal properties needed for high-temperature applications. Thus, the steel core is the preferred choice due to its superior characteristics when dealing with challenging thermal conditions.
