Type 440 Mining Cable Application

Underground Mining

Type 440 cables are extensively utilized in underground mining operations, powering essential equipment such as shuttle cars that transport coal or ore from the mining face to conveyor systems, drill rigs for exploration and production drilling, and conveyor systems that move materials throughout the mine.

Open-Cut Mining

In surface mining environments, Type 440 cables supply power to massive equipment like draglines that remove overburden, mobile substations that distribute power across mining sites, and electric shovels that excavate and load materials.

Tunnel Boring Operations

During tunnel construction, Type 440 cables provide temporary power to boring machines, lighting systems, and auxiliary equipment.

Harsh Industrial Environments

Beyond mining, these cables are suitable for any industrial setting characterized by high mechanical stress, abrasive conditions, and challenging operational parameters.
