Introduction
In the harsh, rugged environment of underground mining, coal cutting machines and other mobile equipment require a power supply connection that can withstand extreme mechanical stress, frequent flexing, and harsh environmental conditions. This is where Feichun Cable's Type (V) NSSHCGEOEU 0.6/1KV coal cutter cable excels. With its robust design and high-performance features, this cable ensures uninterrupted power delivery, enhancing productivity and safety in mining operations.
Feichun Cable Type (V) NSSHCGEOEU 0.6/1KV Coal Cutter Cable with Concentric Earth Conductor
Feichun’s Type (V) NSSHCGEOEU is a specialized coal cutter cable designed to deliver consistent power in the most demanding chain operation scenarios. Rated at 0.6/1KV (Um 1.2KV), it excels in underground mining and open-pit environments, trailing behind coal cutting machines, conveyor drives, stacker-reclaimers, and drilling jumbos within cable protection chains that absorb heavy tensile forces.
Key Features & Construction
The Type (V) NSSHCGEOEU 0.6/1KV cable boasts a range of features that make it ideal for mining applications:
Concentric Earth Conductor
One of the standout features of this cable is its concentric earth conductor. This helically applied steel-copper braid is situated between the inner and outer sheaths, providing a robust earth path and mechanical reinforcement. This design ensures that the cable can handle the mechanical stresses and electrical demands of mining operations.
Flexible Copper Cores
The cable utilizes very finely stranded tinned copper (class FS) conductors, which offer maximum flexibility and resistance to metal fatigue. This flexibility is crucial in mining environments where the cable must navigate around machinery and through confined spaces without breaking.
EPR Insulation (PROTOLON)
The heat-resistant rubber core insulation, known as PROTOLON, maintains dielectric integrity up to 90°C. This insulation can withstand the thermal cycling associated with the frequent starts and stops of heavy machinery, ensuring consistent power delivery.
Outer Conductive Layer
Beneath the inner sheath, an easy-strip semi-conductive rubber layer facilitates smooth conductor transitions and controlled stress distribution. This layer enhances the cable's overall reliability and durability.
Inner & Outer Sheaths
The cable's inner and outer sheaths provide additional protection:
- Inner Sheath: The EPR compound GM1b protects the cores from mechanical abrasion.
- Outer Sheath: The PROTOFIRM PCP sheath offers resistance to oil, ozone, UV, and water, making it suitable for splash zones and temporary immersion.
Mechanical & Environmental Performance
The Type (V) NSSHCGEOEU 0.6/1KV cable is designed to perform reliably under rigorous mechanical and environmental conditions:
- Tensile Strength: Rated at 15 N/mm², it withstands the pull-out forces of cable handlers.
- Torsional Endurance: The cable accommodates ±25°/m of twist without damaging the conductors.
- Bending Radius: The minimum bending radius is 2.3 × D under tensile load, with a recommended 20 × D between direction changes to prevent kinking.
Temperature Range
The cable is built to operate in a wide range of temperatures:
- Fixed: –40°C to 80°C
- Flexible: –20°C to 60°C
Short-Circuit Rating
In the event of a fault condition, the conductor temperature can rise up to 250°C, ensuring that the cable can handle short-circuits without failing.

Additionally, the cable is approved by MSHA P-07-KA140034, MA China, EAC, and BAS Bosnia-Herzegovina. It is also compliant with RoHS and the Low Voltage Directive (2014/35/EU).
Ideal Applications
The Type (V) NSSHCGEOEU 0.6/1KV cable is engineered for a variety of mining applications where its durability and flexibility are paramount:
Coal Cutter Power Feeds
This cable is ideal for trailing behind shearers and continuous miners in cable chains. Its robust construction ensures it can withstand the constant movement and mechanical stress associated with these machines.
Conveyor & Stacker Drives
In conveyor and stacker systems, the cable resists abrasion on idler rollers and long travel distances. Its flexibility allows it to navigate the complex routing paths typical in these systems.
Drill Jumbo & Bolter Cables
For drill jumbos and bolters, the cable’s flexible routing capabilities are essential in confined drift headings. It can bend and twist without damaging the conductors, ensuring reliable power delivery.
Reclaimer & Shuttle Car Lines
The cable's ability to withstand frequent flexing, torsion, and exposure to hydraulic fluids makes it ideal for reclaimer and shuttle car lines. These applications require a cable that can handle the harsh conditions and constant movement.
Conclusion
Feichun’s Type (V) NSSHCGEOEU 0.6/1KV coal cutter cable combines robust mechanical design, premium materials, and stringent certification, delivering uninterrupted power and extended service life in the harshest mining conditions. Whether it’s powering coal cutters, conveyors, drill jumbos, or other mobile equipment, this cable is engineered to meet the demanding requirements of underground mining and open-pit environments.
In my experience, the reliability and durability of the Type (V) NSSHCGEOEU 0.6/1KV cable make it an invaluable asset in any mining operation. Its ability to withstand extreme mechanical stress and harsh environmental conditions ensures that it will continue to deliver consistent power, enhancing both productivity and safety.
