Any mine uses electricity for a variety of tasks, both underground and on the surface. The necessary electrical power is either obtained through a substation from the nearby electricity supply or, more frequently, from a generating station at the mine.
It is common knowledge that cables used underground at coal mines must resist challenging circumstances, including exposure to roof falls, moisture, and other potential damage-causing factors.
Therefore, Mining cables need to be sturdily constructed to endure the harsh use they experience. In addition, ongoing maintenance is necessary to guarantee their dependability and safety. In actuality, sturdy and dependable cables are crucial for effective coal production.
The primary high- and medium-voltage distribution lines in the mines now employ PVC/XLP insulated cables with metric dimensions. The identical cables were used in inch sizes before metric cable sizes were introduced. In reality, the imperial or inch-sized wires are still in use. Additionally, before PVC-insulated cables were utilized, paper-insulated lead-sheathed cables were the most often used cable.
There is still a sizable number of this kind of cable in use. There are cables available with two to four conductors. Three core cables—one for each phase of the supply system—are often used for three-phase a.c. distribution.
Electricity is needed in many mine locations, both above and below ground. Excellent flexibility, resistance to drag, and torsion resistance are all features of a mining cable's design. These cables retain appropriate temperature characteristics and have great abrasion resistance. A mining power cable is an electrical wire created by joining numerous conductors. They are protected from various elements in the mine by a sheath that covers them.
High-performance materials are used to create mining wire. This makes it possible for electricity to move smoothly between several mine locations. These wires are wrapped with other similar wires and covered in insulation tape. We are one of India's leading producers of mining cables. Our goal is to create the greatest items for everyone at fair prices.
An underground Mining Cable is made to survive adverse weather, roof collapses, moisture, and other hazards that are frequent in mine locations. These wires are extremely dependable and robust. A vertical wire shaft called the Mining Riser Cable aids in improving the efficiency of electric transfer. The fire resistance standards required for installation in a vertical system are met by these cables.
A mobile machine or a fixed system line both employ trailing cables. Galvanized wires or other protective materials are used to substantially insulate and protect these cables. All of our goods, including the mining GPU cable, may be made to order in various sizes and forms by our highly skilled employees to suit your specific requirements.
Many mining applications use flex braided mining cables where a flexible thermal conductivity connector is needed. These cables can transport large voltages with ease in a variety of underground holes. For use in high-temperature and high-pressure applications, they can be press welded, nickel-coated, or coated with tin. In the mining system, voltage is significant. Applications that call for low-voltage electricity use the low-voltage mining cable. In mine sites, they are frequently used to link electric lights and phones and have a voltage of 0.6/1 kV.
The voltage in these locations is controlled by a large number of plugs and sockets. Volts are delivered by the medium-voltage mining cable at 1kV to 100kV. We deal with both static and dynamic products, which are created with the best raw materials and cutting-edge technology to create products of the highest caliber available on the market.

What is Reeling and Trailing Cable?
Electrical power cables for mobile equipment such as huge excavators, draglines, stackers, and reclaimers are known as trailing and reeling cables. The cable enables the mobile device to travel without cutting off its electrical power source.
Cable reeling and trailing present a significant risk to safety (e.g., a damaged trailing cable can lead to earth faults and workers being exposed to electric shock hazards). The Mine Safety and Inspection Regulations of 1995 provide details on the precise design mitigation measures that are required.
A trailing cable is made to travel with the mobile apparatus, but a reeling cable is made to be frequently reeled on and off a cable drum or reeler (such as an iron ore rail-mounted reclaimer) (e.g., a coal mine dragline, a mineral sands mobile processing plant).
Design Guidelines for Cables Used for Reeling and Trailing
Cables for reeling and trailing must adhere to Australian Standard AS 2802, "Electric cables—Reeling and trailing—For mining and general use (other than underground coal mining)" and have a pilot core set up to switch off the electrical supply in the case of a break in the earthing circuit.
The pilot core enables the pilot earth loop or earth continuity monitoring protection to work once an earth continuity relay and related connections of the protection system are connected.
