PUR D2X11Y 1 KV REELING CABLE FOR DRILLS AND LHD
Feichun PUR D2X11Y 1 KV REELING CABLE FOR DRILLS AND LHD
Application:
This is a flexible low voltage reeling cable with optimized dimensions and flame retardant, halogen-free polyurethane outer sheath. The cable is used as power supply for underground mining and tunnelling equipment and designed for frequently changing dynamic loads, such as reeling operation on drilling machines, scoops and LHD’s. Suitable to withstand the high mechanical stresses caused by reeling application and the abrasion to be expected in trailing operation.

In underground mining and tunnelling operations, power cables are exposed to extreme mechanical stress, frequent reeling, abrasion, torsion, moisture, and confined environments. Choosing the wrong cable can lead to premature failures, safety risks, and costly downtime.
Feichun PUR D2X11Y 1 kV Reeling Cable is specifically engineered for drilling rigs, scoops, and Load–Haul–Dump (LHD) machines, where cables must perform reliably under continuous dynamic movement.
What Is Feichun PUR D2X11Y 1 kV Reeling Cable Designed For?
Feichun PUR D2X11Y is a low-voltage (0.6/1 kV) flexible reeling cable designed for underground mining and tunnelling equipment subject to:
Continuous reeling and unreeling
High tensile and torsional stress
Severe abrasion during trailing operation
Confined spaces with strict fire and halogen-free requirements
It is commonly used as a power supply cable for:
Underground drilling machines
LHDs (Load–Haul–Dump machines)
Scoops and bolters
Mobile tunnelling equipment
How Is Feichun PUR D2X11Y Cable Structurally Designed for Reeling Applications?
The cable structure is optimized to balance flexibility, mechanical strength, and electrical stability.
What Type of Conductor Is Used and Why Does It Matter?
Finely stranded bare copper conductor (Class 5)
Conforms to DIN EN 60228 / IEC 60228 / VDE 0295
Why this matters:
Class 5 stranding ensures excellent flexibility, reducing conductor fatigue during repeated bending and reeling cycles.
Why Is XLPE Used as Core Insulation?
Each power core is insulated with XLPE (cross-linked polyethylene).
Key advantages of XLPE:
High thermal resistance (90 °C continuous)
Excellent dielectric strength
Superior ageing performance
Lower insulation losses compared to PVC
What Is the Purpose of Split Earth Conductors?
Feichun PUR D2X11Y uses a split earth conductor design, laid symmetrically around the main cores.
Benefits include:
Improved earth continuity during cable movement
Enhanced safety for mining personnel
Better mechanical balance during reeling
How Are the Cores Arranged to Withstand Dynamic Stress?
Three main power cores laid together
Split earth conductor and control cores placed in interstices
Very short lay length twisting to minimise internal stress
Core identification:
Main cores: brown, black, grey
Control cores: blue, white
Why Are Halogen-Free Inner and PUR Outer Sheaths Critical?
Inner sheath: Halogen-free polymer
Outer sheath: Flame-retardant polyurethane (PUR)
PUR advantages in mining:
Exceptional abrasion resistance
High cut and tear strength
Resistance to oils, grease, moisture, and chemicals
Long service life under harsh reeling conditions
What Are the Best Installation Practices for PUR D2X11Y Reeling Cables?
Use properly aligned reeling drums
Avoid exceeding the specified bending radius
Ensure even cable winding to prevent torsional stress
Inspect outer sheath regularly for mechanical damage
Avoid sharp edges and pinch points
