What Applications Are PUR HF Antitwisting 1 kV Cables Designed For?

PUR HF antitwisting power cables are purpose-built for mobile equipment operating under continuous movement and mechanical stress, particularly where twisting forces can damage conventional flexible cables.

Typical Applications Include:

Underground mining equipment
Tunnelling machines and roadheaders
Mobile crushers and conveyors
Drilling rigs and LHD (Load–Haul–Dump) machines
Equipment on cable reels and drums
Mobile substations in harsh environments

With a maximum travel speed of 120 m/min, these cables are suitable for dynamic reeling and trailing operations, where cable rotation and torsional fatigue are major failure risks.

How Does This Cable Perform Mechanically?

Mechanical Performance Highlights:

Maximum travel speed: 120 m/min
High tensile strength (up to 14,400 N depending on size)
Bending radius:
- Fixed installation: 6 × D
- Drum/reeling operation: 10 × D

This makes the cable ideal for frequent movement without conductor fatigue.

What Are the Best Installation Practices?

How Should PUR HF Antitwisting Cables Be Installed?

Respect minimum bending radius (especially on drums)
Avoid forced twisting during installation
Use compatible cable reels with smooth guidance
Ensure adequate strain relief at termination points
Regularly inspect outer sheath for abrasion

Correct installation maximises service life and safety performance.

Frequently Asked Questions (FAQ)

Is this cable suitable for continuous reeling?

Yes. It is specifically designed for dynamic reeling and trailing applications up to 120 m/min.

Can it be used in underground mining?

Absolutely. Its halogen-free, flame-retardant PUR sheath makes it ideal for underground and confined spaces.

Does the antitwisting layer replace steel reinforcement?

No. The synthetic mesh is designed for torsional stability, not tensile reinforcement like steel braiding.

Is it compliant with international standards?

Yes. It complies with IEC, DIN EN, and VDE standards, making it suitable for global mining projects.

How Do You Choose the Right PUR HF Antitwisting Cable?

Ask yourself:

Is the cable subjected to torsional stress?
Is fire safety a critical requirement?
Will the cable be used on drums or moving equipment?
Do you need integrated control cores?

If the answer to these questions is “yes,” this cable is a strong candidate.
