Type 241 Mining Cable

Type 241 Mining Cable Description:

Type 241 Mining Cable form part of the mining equipment cable portfolio, suitable for general mining and underground mining applications. These include mine supply cables for continuous miners, pump connection cables, longwall supply cables, and power cables for mining equipment. The voltage range spans 1.1kV to 11kV, with an operating temperature range of -25°C to 90°C. All feature flexible tinned copper conductors，EPR insulation, and a heavy-duty rubber (PCP) sheath for excellent mechanical strength, . Each cable comprises three insulated cores and one monitoring core: the monitoring core provides reinforcement, enabling longer transmission distances without compromising connectivity.

Type 241 Mining Cable Applications

Type 241 Mining Cable is suitable for multiple purposes, including main feeder cables for continuous mining machines, pump cables, and power supply cables. The integral semi-conductive shield provides protective earth contact before any object penetrating the sheath can reach the power conductors.
Type 241 Mining Cable serve as versatile flexible feeder cables for longwall mining systems and other applications requiring mechanical strength and crush resistance. They are also suitable for underground coal mining environments.
