Feichun's (N)TSCGEWOEU 6 - 35 kV medium voltage cable is specifically designed for use in trailing applications, such as those required by mobile mining equipment, where extreme conditions are common. These cables are known for their robust construction, which is able to withstand harsh environmental factors like abrasion, tearing, and extreme temperatures.
What Are the Applications of Feichun (N)TSCGEWOEU Cables?
These cables are primarily used in trailing applications within mines, providing power to large, mobile equipment like shovels and draglines. The tough exterior and flexible design ensure that the cables can withstand the repeated motion of trailing or reeling, even under extreme weather conditions.
Key Applications Include:
Mining: Feichun (N)TSCGEWOEU cables are essential in providing continuous power to heavy equipment in open-pit and underground mines.
Construction Sites: They can be used to power large construction equipment that requires robust, flexible cables.
Harsh Environments: Withstanding temperatures as low as -50°C, these cables are suitable for cold climates where other cables might fail.
Energy Production: They are also used in power generation sites, especially in areas where mobile power units are needed.
Example from South Africa
In South African mines, where extreme temperatures and rugged conditions are common, these cables are frequently used to power large mining trucks and shovels. For example, one case study from a mine in the Limpopo region shows that after using Feichun (N)TSCGEWOEU cables, the mine significantly reduced the frequency of cable failures, ensuring uninterrupted operations.
What Are the Common Questions About Feichun (N)TSCGEWOEU Cables?
1. How do I choose the right cable size for my equipment?
To select the correct size, you need to consider the voltage rating, current-carrying capacity, and the mechanical stress the cable will face. Feichun cables come in various sizes, with current capacities ranging from 99 A to 620 A, depending on the model.
2. Can I use Feichun (N)TSCGEWOEU cables in humid environments?
Yes, these cables are resistant to UV, ozone, and moisture, making them suitable for use in humid environments like mining pits and construction sites.
3. What are the installation guidelines?
Ensure that the cable is installed with the minimum bending radius to avoid mechanical damage. For flexible installations, the cable should not be bent more than 10 times its diameter.
4. Are these cables suitable for long-term use in mines?
Yes, these cables are designed for durability and flexibility, ensuring that they can handle the harsh conditions of underground and open-pit mining.
5. How do I maintain Feichun (N)TSCGEWOEU cables?
Regular inspection for signs of wear and tear, especially on the outer sheath, will help prevent sudden failures. Additionally, ensuring proper installation and following temperature recommendations will prolong the cable's lifespan.
Conclusion
Feichun (N)TSCGEWOEU cables are an ideal choice for mining, construction, and other heavy-duty applications where flexibility, durability, and reliability are paramount. Their robust construction and resistance to extreme temperatures, UV, ozone, and mechanical stress make them perfect for harsh environments.
