What is a PUR-HF Low Voltage Festoon Cable?
The term PUR-HF refers to Polyurethane – Halogen-Free. This type of festoon cable combines mechanical strength with safety-oriented materials. Its unique design allows it to function as:
Energy and control cable in festoon systems, chain systems, and reeling applications.
A flexible connection cable that resists torsion, tensile stress, and mechanical load.
A safe, eco-friendly solution because it is halogen-free, flame retardant, and resistant to oils, solvents, and alkalines.
In essence, PUR-HF festoon cables are engineered for dynamic environments where cables are in continuous motion and exposed to harsh conditions.
Usage Scenarios of PUR-HF Low Voltage Festoon Cable
1. Mining and Mineral Processing
South Africa’s gold, platinum, and coal mines require robust festoon systems for cranes, conveyors, and reeling equipment. PUR-HF festoon cables are ideal due to their abrasion resistance, torsional strength, and flexibility in confined tunnels.
2. Ports and Logistics
Festoon systems are widely used in container cranes and automated logistics hubs. The high travel speed tolerance (up to 200 m/min) makes PUR-HF cables suitable for Gantry Cranes (RTGs), Ship-to-Shore Cranes (STS), and automated storage and retrieval systems.
3. Industrial Automation
In automotive and manufacturing plants, festoon cables power robotic arms, overhead cranes, and moving assembly systems. Their halogen-free design ensures low smoke and toxicity, reducing risks in enclosed spaces.
Case Studies: South African Applications and Trends
Port of Durban Crane Upgrades
Durban, the busiest port in Africa, recently invested in container handling automation. Crane operators reported frequent cable fatigue and jacket cracking due to high UV exposure and fast operating speeds. After switching to PUR-HF festoon cables with yellow outer sheaths for visibility, performance reliability improved, and maintenance cycles were extended.

Frequently Asked Questions (FAQ)
1. Why use PUR-HF festoon cables instead of PVC cables?
PVC cables are cheaper but degrade faster under mechanical and chemical stress. PUR-HF cables offer longer life, environmental safety, and higher reliability.
2. Can PUR-HF festoon cables be used in underground mines?
Yes. Their mechanical strength and halogen-free flame-retardant properties make them safe for confined, hazardous environments such as underground tunnels.
3. Are PUR-HF festoon cables suitable for outdoor use in South Africa’s climate?
Yes. Their temperature resistance (–50°C to +80°C) and UV-resistant polyurethane jacket make them suitable for extreme weather conditions.
4. How do these cables support sustainability goals?
They are halogen-free (reducing toxic emissions in case of fire) and long-lasting, which reduces waste and maintenance.
5. What is the maximum travel speed for festoon applications?
They can operate up to 200 m/min in festoon systems, making them ideal for modern automated cranes and material handling equipment.
The PUR-HF Low Voltage Festoon Cable is more than just an electrical conductor; it is a strategic investment in safety, durability, and operational efficiency. With a robust design, compliance with international and South African standards, and proven case studies in mining, ports, and renewable energy, these cables are becoming indispensable in modern industries.
