BUFLEX Reeling Cable for Mobile Mining Equipment
The BUFLEX 0.6/1kV reeling cable with 2 pilot cores is a low-voltage power and control cable for mobile equipment in mining and tunnelling routes where mechanical damage is a persistent concern. Buyers may also encounter the spelling BUTFLEX cable in project enquiries. This page uses BUFLEX as the product designation while retaining BUTFLEX as a search and cross-reference term.
Three power cores, three divided earth cores and two pilot/control cores share a compact round construction. The central strength member supports the cable assembly, while the yellow halogen-free PUR sheath is specified for abrasion, tearing and hydrolysis resistance. This makes the design relevant to mobile drills, loaders and similar equipment that repeatedly pays cable in and out along a controlled path.
- Suitable for: one-plane reeling or guided movement up to 60 m/min.
- Confirm before ordering: conductor size, reel geometry, route length, tensile load and pilot-core interface.
- Choose another construction when: the route imposes multi-plane flexing, uncontrolled torsion or a different voltage class.

Construction
The BUFLEX cable cross-section shows a compact three-phase layout with divided earth cores, two pilot/control cores and a central strength member. Each confirmed layer has a specific electrical or mechanical function.
| Layer | Confirmed construction | Buyer relevance |
|---|---|---|
| Conductor | Flexible plain copper, Class 5 to IEC 60228 | Fine stranding supports repeated bending in the specified reeling path. |
| Central element | Central strength member | Supports the laid-up core assembly under movement and tensile load. |
| Insulation | XLPE special compound on power, earth and control cores | Separates the power, protective-earth and control circuits within the 0.6/1 kV design. |
| Core identification | Power: brown, black, grey; earth: yellow/green; control: white, blue | Helps installers distinguish circuit functions during termination. |
| Binder | Non-hygroscopic synthetic tape when required by the manufacturing design | Maintains the cable assembly before bedding. |
| Bedding | Special flexible thermoplastic compound | Provides a resilient layer between the core assembly and outer sheath. |
| Outer sheath | Halogen-free special PUR compound, yellow RAL 1018 | Specified for abrasion, tear and hydrolysis resistance in harsh handling environments. |
Ordering check: The two pilot/control conductors sit in the interstitial areas. Confirm their required cross-section and machine interface rather than treating them as spare power conductors.
Applications
This BUFLEX mining reeling cable is intended for mobile equipment operating on a controlled, one-plane cable route. The confirmed 60 m/min maximum speed and 6 × OD minimum bending radius should be checked against the actual reel, sheaves, rollers and travel distance.
- Power and pilot/control connection for mobile mining and tunnelling equipment.
- Reeling routes that bend the cable in one plane only.
- Drilling rigs, loaders and other heavy mobile machinery using guided cable travel.
- Harsh environments where abrasion, tearing and hydrolysis resistance are selection priorities.
Application Boundary
Do not assume suitability for random multi-plane flexing, forced twisting, vertical suspension or continuous submersion. Those duties change the mechanical and environmental requirements. Confirm reel diameter, roller profile, acceleration, tensile load and cable storage arrangement before approving a substitute.
