Type Corda-Flex (SMK) (N) SHTOEU Reeling Cable: Built for ERTG's

If you're looking for power flexible cables that can handle the most demanding conditions, especially in ERTG’s (Electrified Rubber Tyred Gantry Cranes), you’ve come to the right place.

The Type Corda-Flex (SMK) (N) SHTOEU Reeling Cable is designed for maximum performance, providing a durable and flexible solution for high mechanical stress environments.

The Importance of Cables for ERTG's

ERTG’s (Electrified Rubber Tyred Gantry Cranes) are essential for moving heavy containers at shipping ports, offering efficiency in port logistics. These cranes operate under intense conditions where reliable power transmission is non-negotiable.

Whether it's for lifting, transporting, or positioning cargo, ERTG's require a robust reeling cable that can withstand high mechanical stresses while maintaining flexibility and durability.

The Corda-Flex (SMK) (N) SHTOEU Reeling Cable is specifically designed to meet these rigorous demands.

Our long-term collaboration with Shanghai Zhenhua, the world’s largest gantry crane manufacturer, has led to the development of a product that addresses real-world challenges.

By closely working with leading crane manufacturers, we ensure that our cables are built to last, even under the most demanding operational conditions.

Flexible Design for Maximum Performance

One of the key features of this reeling cable is its flexible design. Flexibility is crucial in environments where cables must move continuously without breaking or wearing out prematurely.

In ERTG’s, cables are subjected to extreme bending, torsion, and tension as they reel in and out with the crane’s movements. The Type Corda-Flex (SMK) (N) SHTOEU excels in this application by offering high flexibility without compromising on strength or performance.

The flexibility also extends to how the cable handles reeling operations. With a carefully engineered inner and outer sheath system, the cable ensures smooth reeling and unreeling even at high speeds.

This makes it an ideal choice for cranes and heavy equipment in ports where time and efficiency are critical.

What Does the Cable Model Stand For?

The model name Type Corda-Flex (SMK) (N) SHTOEU might look complex, but each part has a specific meaning that reflects the cable's design and intended use:

Corda-Flex: Indicates that the cable has high flexibility, making it suitable for applications where it needs to move frequently without damage.

(SMK): Refers to the cable’s special mechanical characteristics, including enhanced tensile strength and torsional resistance.

(N): Refers to the cable's classification under European standards, ensuring it meets strict quality and performance guidelines.

SHTOEU: Represents the sheath material and its weather-resistant qualities. This cable is designed for use in outdoor environments, withstanding exposure to UV rays, moisture, and other environmental factors.

Design Features and Construction

Insulation

The cable's insulation is made from a special compound based on high-quality EPR (Ethylene Propylene Rubber), which provides both improved mechanical and electrical characteristics.

This ensures that the cable remains functional and safe, even under high-stress conditions. The insulation is designed to handle voltages up to 600/1000V, with a maximum permissible operating voltage of 0.7/1.2 kV in AC and 0.9/1.8 kV in DC.

Core Identification

The core identification system includes light-colored insulation with numbers printed in black for power and control cables, while the earth conductor is green-yellow.

This identification system ensures easy and clear recognition of different cable components during installation and maintenance, reducing the likelihood of errors.

Optical Fiber Properties

In certain configurations, the cable can include integrated fiber optics, providing reliable and high-speed data transmission.

The fiber-optic cores are designed to meet the needs of modern data communication systems, allowing for seamless operation of automated processes in crane systems.

Fiber types: G62.5/125μm, G50/125μm, and E9/125μm.

Core diameters: 62.5μm, 50μm, and 9μm for different fiber types.

Attenuation: Less than 3.3dB/km at 850nm and less than 0.9dB/km at 1310nm, ensuring minimal data loss over long distances.

Bandwidth: Greater than 400MHz at 850nm and 1200MHz at 1310nm, making this cable ideal for high data rate applications.

Inner and Outer Sheaths

The inner sheath is made from PROTOFIRM Special Compound, which is known for its superior mechanical protection while maintaining the flexibility required for reeling applications. The outer sheath is also made from PROTOFIRM Special Compound, combining flexibility and robustness to provide a cable that can perform in both indoor and outdoor environments.

The outer sheath is designed to be resistant to ozone, UV rays, and moisture, making it suitable for unrestricted use outdoors and indoors. The material is also resistant to oil, ensuring that the cable can perform in various industrial settings where oil exposure is common.

Electrical Parameters

The Type Corda-Flex (SMK) (N) SHTOEU Reeling Cable is rated for a nominal voltage of 0.6/1kV. It can handle up to 0.7/1.2kV for AC operations and 0.9/1.8kV for DC operations, making it suitable for heavy-duty applications like ERTG’s.

AC test voltage: 3.5kV for 5 minutes, ensuring the cable can withstand surges and electrical stresses without failure.

Max. operating temperature: The conductor can handle up to 90°C during normal operation, and 250°C in short circuit conditions.

Ambient temperature: The cable can operate in temperatures ranging from -50°C to +80°C for fixed installations and from -35°C to +80°C in fully flexible operations.

Mechanical Parameters

The Type Corda-Flex cable is engineered to handle extreme mechanical conditions:

Max tensile load: The cable can support up to 30 N/mm² on the conductor, allowing it to endure high tension without breaking.

Bending radius: The cable can be bent to tight radii without damaging the internal structure, ensuring long life even in reeling applications.

Additionally, the cable has been tested for reversed bending, roller bending, and torsional stress, making it a perfect fit for ERTG's and other high-stress equipment.

Long-Term Durability

When selecting a reeling cable for ERTG's, long-term durability is key. The Corda-Flex (SMK) (N) SHTOEU offers superior resistance to environmental factors, such as oil, ozone, UV light, and moisture.

Its water-resistant design has been verified through long-term tests, ensuring it can withstand both dry and wet environments without degrading.
