Product Overview
The Type 441 Class 2 mining cable is engineered for versatile performance in demanding mining environments, suitable for both trailing and reeling applications. Its distinctive construction features a semi-conductive cradle that supports and protects the power cores, significantly reducing the likelihood of damage from crushing and squashing during operation. With a central pilot conductor for monitoring and robust interstitial earth conductors, this cable provides reliable power distribution and safety in mobile mining equipment.
