Flexibility in Design: What the Model Letters Mean

Understanding the model name of the Trommel-Flex (K) NSHTOEU cable provides insight into its specific features and benefits:

Trommel-Flex: Refers to the cable's flexibility and its suitability for reeling applications where the cable needs to withstand dynamic movement.

(K): Indicates that the cable has added mechanical protection.

NSHTOEU: Specifies that the cable is built according to the standards for reeling cables in harsh environments, offering exceptional mechanical stress resistance and oil resistance.

This careful attention to detail in the cable's naming convention ensures that it is purpose-built to handle medium mechanical stresses, making it ideal for a wide range of industrial applications.

Built for Tough Industrial Applications

The Type Trommel-Flex (K) NSHTOEU Flexible Reeling Cable is built to perform in medium mechanical stress environments, ensuring long-lasting durability and reliable performance. Its flexible design makes it perfect for applications that demand continuous movement and high mechanical resilience, such as cranes, mining equipment, and other heavy-duty industrial machinery.

Whether you're dealing with intense wear and tear from reeling or operating in oil-rich environments, this cable is designed to withstand these tough conditions while maintaining performance.

Conductor and Insulation: Strength Meets Flexibility

The conductor of the cable is made from tinned copper, flexible class 5 according to DIN EN 60228 / DIN VDE 0295. Tinned copper provides corrosion resistance, ensuring that the cable can perform reliably in harsh, oil-laden, or moisture-heavy environments. The flexible class 5 conductor ensures superior flexibility, allowing for easy handling and installation in dynamic applications.

The insulation is crafted from a rubber compound type 3GI3, which conforms to DIN VDE 0207-20 standards. This rubber insulation provides excellent electrical insulation properties, enhancing the overall safety and performance of the cable, even in high-temperature or chemically aggressive environments.

Core Identification and Arrangement

For ease of installation and troubleshooting, the core identification varies depending on the number of cores:

Up to 5 cores: The cores are colored according to DIN VDE 0293-308, making it simple to identify and connect the correct wires during installation.

More than 6 cores: Black cores with white numbers make it easy to identify and differentiate between wires, even when dealing with complex cable assemblies.

The core arrangement includes a central filler, either plastic or textile, covered with rubber if necessary. The cores are twisted at a short length of lay, enhancing the cable's mechanical strength and flexibility.

This design allows the cable to handle medium mechanical stresses without compromising its electrical performance.

Inner and Outer Sheath: Protection Against the Elements

The inner sheath of the cable is made from rubber compound type 5GM3, as specified by DIN VDE 0207-21. This rubber sheath provides excellent protection against abrasion, tearing, and other physical stresses, while remaining flexible enough to handle dynamic movements in reeling applications.

For additional protection, the cable is equipped with torsion protection, which consists of a wide-meshed polyester braid embedded in the sheath. This extra layer of protection ensures that the cable can handle twisting and bending movements without damage, even in the most demanding environments.

The outer sheath is also made from extruded rubber compound type 5GM3, providing exceptional abrasion and tear resistance.

The outer sheath is both oil and flame resistant, which is vital for industrial applications where exposure to harsh chemicals, oils, and heat is common.

The cable’s black color gives it a sleek appearance while providing an additional layer of UV protection when used in outdoor or exposed applications.

Electrical Performance: Designed for Safety and Efficiency

When it comes to electrical parameters, the Trommel-Flex (K) NSHTOEU Flexible Reeling Cable is built to handle the toughest challenges. It has a rated voltage of 0.6/1 kV (600/1000V), making it suitable for a wide range of industrial equipment and machinery.

The maximum permissible operating voltage is 0.7/1.2 kV for AC and 0.9/1.8 kV for DC, ensuring that the cable can handle higher loads when necessary. It also features a test voltage of 2.5 kV for the main cores, ensuring safety and reliability during operation.

This cable complies with the DIN VDE 0298-4 standard for current-carrying capacity, ensuring that it can safely carry the required electrical loads without overheating or compromising performance.

Chemical Resistance and Fire Performance

One of the standout features of the Trommel-Flex (K) NSHTOEU cable is its chemical resistance, especially against oil. The cable complies with the EN 60811-404 standard for oil resistance, which is crucial in industrial environments where oil exposure is a constant challenge.

In addition to its oil resistance, the cable is built to perform well in terms of fire safety. It meets the requirements of IEC 60332-1 (EN 50265-2-1) for fire performance, ensuring that it will not propagate flames in case of a fire. This makes it a safer choice for industrial settings where fire hazards are a concern.

Thermal Parameters: Performance Under Extreme Temperatures

The Trommel-Flex (K) NSHTOEU Flexible Reeling Cable is built to handle extreme temperatures, with a maximum operating temperature of 90°C for the conductor and a short-circuit temperature of up to 250°C. This ensures that the cable can operate safely and efficiently even in environments where heat is a major factor.

For fixed installations, the cable can withstand ambient temperatures ranging from -40°C to +80°C, while for fully flexible operations, it can handle temperatures between -25°C and +80°C.

Mechanical Performance: Built to Last

When it comes to mechanical parameters, the Trommel-Flex (K) NSHTOEU cable delivers outstanding performance. The cable can withstand a maximum tensile load on the conductor of 15 N/mm², making it ideal for applications where pulling and stretching are common.

It also features torsional stress resistance of +/- 50°/m, allowing it to handle twisting movements without damage. The bending radii are designed according to DIN VDE 0298 part 3, ensuring that the cable remains flexible while maintaining its structural integrity.
