Premium 0.6/1kV Crane Travelling Cable for High Mechanical Stress
When operating large-scale industrial machinery, the reliability of your power transmission is critical. The TEBAOFLEX 0.6/1kV HTC series (including HTC-FP2, HTC-FP3, HTC-RP2, HTC-RP3) is an advanced, heavy-duty crane travelling cable explicitly engineered to withstand the harshest environments. Designed as a flexible medium-voltage reeling cable, it handles extreme dynamic tensile loads, multiple changes of direction within one plane, and continuous running over rollers without compromising electrical integrity.
Why Choose the TEBAOFLEX Crane Travelling Cable?
As a leading factory-direct manufacturer, TEBAOFLEX produces this crane travelling cable using superior materials that ensure longevity and safety. The insulation is crafted from premium Ethylene Propylene Rubber (EPR), providing excellent thermal and electrical stability. The robust outer sheath is made of PCP (Polychloroprene) or similar high-grade mixtures, offering unparalleled resistance to oil, UV rays, weather, and severe abrasion.
To learn more about international electrical standards for heavy machinery, you can refer to the official International Electrotechnical Commission (IEC) guidelines.
Primary Applications in Heavy Industry
Our heavy-duty crane travelling cable is the backbone of mobile power systems worldwide. It is primarily utilized for:
- Port Terminals: Fast-moving container cranes, Ship-to-Shore (STS) cranes, and Rubber Tyred Gantry (RTG) cranes.
- Mining Operations: Large mobile equipment, heavy-duty excavators, and tunneling machinery.
- Steel Mills & Logistics: Material handling systems requiring continuous reeling and flexing under high mechanical stress.
Detailed Cable Construction
The internal structure of our 0.6/1kV HTC-FP2(S) crane travelling cable is meticulously designed to prevent core breakage during constant movement. The construction layers are as follows:
- Main Conductor: Tin-plated copper wire (TA), Class 5 flexibility.
- Control Conductor: Tin-plated copper wire (TA), Class 5 + Stainless steel wire (St) for ultimate tensile strength.
- Insulation: Cross-linked Ethylene Propylene Rubber (EPR).
- Wrapping: Protective binding tape.
- Property Filler: High-tensile Martha/textile fillers for structural integrity.
- Shielding: Braided tin-plated copper wire (TA) to prevent electromagnetic interference (EMI).
- Inner Tape: Additional protective tape layer.
- Outer Sheath: Heavy-duty Black PCP or similar rugged mixture.

Frequently Asked Questions (FAQ)
1. Why is stainless steel wire included in the conductor?
In high-stress applications, a crane travelling cable is subjected to massive pulling forces. The addition of stainless steel wire (St) in the control cores (2.5mm² and 1.5mm²) absorbs the mechanical tension, protecting the copper wires from breaking and ensuring continuous signal transmission.
2. Can this cable operate in freezing port environments?
Yes, the TEBAOFLEX cable features a cold-resistant PCP sheath and EPR insulation, allowing it to remain highly flexible in temperatures as low as -35°C during dynamic operations, and up to -50°C when statically installed.
3. Do you offer custom cable configurations for bulk orders?
Absolutely. As a direct source factory, we can manufacture customizable cables tailored to your specific port machinery or excavator requirements. Please contact our engineering team for bulk pricing and custom specifications.
