NSSHKCGEOEU Mining Cable Feature

Durability: Its robust construction makes it suitable for the most demanding and harsh environments in the mining industry.
Safety: The built-in monitoring system provides early warnings for potential issues, preventing failures and ensuring a safer working environment.
Performance: Maintains exceptional performance and reliability even under extreme conditions such as high-speed operation, oil contamination, humidity, and temperature fluctuations.
Ultimate Flexibility: Specifically engineered for “drag-type” or “reel-type” cables, capable of repeated bending, coiling, and uncoiling as equipment moves.
Superior Mechanical Protection: Heavy-duty rubber sheathing and robust construction effectively resist crushing, cutting, and severe abrasion caused by rough mine surfaces and sharp rocks.
