Type 260 Mining Power Cable Reinforced Steel Wire (SWA) Armored Protective Layer: The Ultimate Solution for Basalt and Granite Deposits

When it comes to mining operations in tough environments like basalt or granite deposits, selecting the right power cable is crucial for ensuring both safety and efficiency.

The Type 260 Mining Power Cable with a reinforced Steel Wire Armored (SWA) protective layer is designed to meet these challenges head-on. Engineered in compliance with the highest Australian standards, this cable is the ideal solution for mining in harsh environments where ordinary trailing cables simply won't suffice.

Understanding the Challenges of Mining in Basalt and Granite Deposits

Mining in environments dominated by hard rock formations such as basalt, granite, quartzite, and iron ore comes with its own set of unique challenges. These types of deposits are characterized by their extreme hardness, making them difficult to excavate and process.

Additionally, the process of breaking down these rocks often results in the scattering of solid small rock fragments and sharp-edged rocks across the mining site.

In such rugged environments, conventional trailing cables are highly susceptible to damage. The constant friction and contact with these sharp fragments can quickly wear down the sheath insulation of the cables, leading to tears, exposure of the internal conductors, and ultimately, cable failure.

This not only poses a serious safety risk but also results in costly downtime as damaged cables need to be repaired or replaced.

Why the Type 260 Mining Power Cable Stands Out

The Type 260 Mining Power Cable is specifically designed to overcome these challenges. Its most distinctive feature is the reinforced Steel Wire Armored (SWA) protective layer, which provides unmatched durability and protection in the most demanding mining conditions.

Advanced Armoring for Superior Protection

The SWA protective layer used in the Type 260 Mining Power Cable is far more advanced than the standard armoring found in ordinary SWA cables. This layer is woven from ultra-soft and fine steel wire, which provides exceptional flexibility without compromising on strength.

This means that the cable can bend and move easily during operation, reducing the risk of kinks and damage that can occur with more rigid armored cables.

The steel wire used in this protective layer is also tinned to prevent oxidation, which is crucial in mining environments where moisture and corrosive elements are often present.

The result is a highly flexible yet incredibly durable cable that can withstand the rigors of mining in environments full of sharp rock fragments.

How This Armored Cable Maximizes Protection

In a typical mining environment, cables are exposed to a wide range of mechanical stresses. The constant movement of equipment, combined with the abrasive nature of the surrounding rocks, can cause significant wear and tear on ordinary cables.

The Type 260 Mining Power Cable addresses these issues head-on:

Friction Resistance:

The ultra-soft steel wire braiding provides a smooth surface that resists friction, preventing the cable from wearing down even when it is dragged across sharp rocks.

Impact Resistance:

The tightly woven steel wires absorb and distribute the force of impacts, protecting the internal conductors from damage even in the event of sudden shocks.

Flexibility:

Despite its rugged construction, the Type 260 cable maintains excellent flexibility, allowing it to be used in applications where the cable needs to bend and flex frequently.

Compliance with Australian Standards: Safety and Reliability Guaranteed

One of the key selling points of the Type 260 Mining Power Cable is its compliance with Australian standards. Australian standards are among the strictest in the world when it comes to mining safety and equipment durability.

By choosing a cable that meets these standards, you are ensuring that your operations are not only compliant but also optimized for safety and reliability.

Australian standards cover everything from the materials used in the cable's construction to its performance under stress.

This means that the Type 260 cable has been rigorously tested to ensure it can withstand the harsh conditions found in basalt and granite mining operations.

Structural Characteristics of Basalt and Granite Deposits

To fully appreciate the importance of using a specialized cable like the Type 260 Mining Power Cable, it's essential to understand the nature of basalt and granite deposits.

Basalt is an igneous rock that forms from the rapid cooling of basaltic lava exposed at or very near the surface of the Earth. It is highly dense, durable, and often used in construction due to its strength.

Granite, on the other hand, is a coarse-grained igneous rock composed mainly of quartz, mica, and feldspar. It is one of the most durable stones used in construction, and like basalt, it poses significant challenges in mining due to its hardness and the sharpness of its fragments when broken.

In mining operations where these types of rock are present, the small, sharp-edged rock fragments produced during excavation can easily damage standard cables.

The Type 260 Mining Power Cable is designed to withstand these conditions, providing superior protection against the physical and environmental stresses found in such deposits.

Applications

 

These armoured cables are mainly used as feeder cables for power supply where mechanical protection and strength is required, and also can be the feeder to machinery and i.e. transportable mining substation (sand mining).
