When it comes to heavy-duty industrial applications such as vertical spreader reels, choosing the right cable is crucial. The D12YST11YU11Y-JZ, a PUR-HF vertical reeling cable, is designed to handle extreme mechanical stress while maintaining high electrical performance. But what sets this cable apart from others, and why is it becoming a preferred choice in industries around the world, including Indonesia?
What Is the D12YST11YU11Y-JZ Reeling Cable?
The D12YST11YU11Y-JZ is a flexible low-voltage reeling cable with a rated voltage of 0.6/1 kV (600/1000 V), designed specifically for vertical reeling operations, commonly found in spreader reel systems. Manufactured by SPREADER REEL, it complies with DIN VDE 0295 and uses halogen-free polyurethane (PUR-HF) sheathing for enhanced safety and environmental performance.
Its primary purpose is to provide reliable power transmission under high mechanical stress, including tension, torsion, and bending cycles, which are typical in vertical reeling applications. Unlike standard cables, it combines flexibility with durability, making it suitable for harsh industrial environments and even underwater use (up to 50 meters depth, excluding drinking water).
Where Is the D12YST11YU11Y-JZ Used in Real Life?
The D12YST11YU11Y-JZ is widely used in ports, container terminals, and industrial facilities. Its primary application is in vertical reeling operations, such as spreader reels on ERTG (Electrified Rubber Tyred Gantry) cranes, which require fast, repeated vertical movement.
Case Study: Indonesia Container Terminals
In Indonesia, several container terminals have adopted the D12YST11YU11Y-JZ cable for their vertical spreader reels. Engineers reported:
Reduced maintenance downtime due to the cable’s high abrasion and oil resistance.
Enhanced safety, thanks to halogen-free materials and flame-retardant properties.
Long-term cost savings, as the cable tolerates repeated flexing at high speeds (up to 180 m/min) without significant wear.
This real-world example demonstrates the cable’s adaptability to tropical climates, high humidity, and high operational loads common in Indonesia.
What Are the Advantages of Halogen-Free PUR Sheathing?
Halogen-free PUR sheathing is a standout feature of the D12YST11YU11Y-JZ:
Fire Safety – Does not release toxic or corrosive gases in case of fire.
Mechanical Resistance – High resistance to abrasion, cuts, and impact.
Chemical and Oil Resistance – Can withstand industrial oils and chemicals, increasing service life.
Environmental Compliance – Safer for workers and environmentally friendly compared to PVC cables.
This combination makes the cable especially suitable for industrial and port applications, where both safety and durability are paramount.
How to Install the D12YST11YU11Y-JZ Cable Correctly?
Proper installation is crucial for longevity:
Use proper clamps – Ensure tensile loads are taken up by kellum grips or similar supports.
Maintain bending radius – Follow the minimum bending radius of 6 x D to prevent mechanical stress on conductors.
Avoid torsion beyond ±50°/m – Excessive twisting can damage cores.
Consider S-type directional changes – Maintain at least 20 x D spacing to reduce bending fatigue.
Check temperature limits – Ensure operating environment stays within -40°C to +80°C for flexible applications.
Following these guidelines ensures maximum performance and extended service life.
