In today's demanding industrial environments, selecting the appropriate reelable cable for hoists, conveyors, and energy supply chains is crucial for maintaining operational efficiency and safety. The NSHTÖU Crane PUR Cable represents a sophisticated engineering solution designed specifically for applications requiring low to medium mechanical stress while maintaining exceptional durability and performance reliability.

Product Overview

The NSHTÖU Crane PUR Cable is a VDE-certified reelable cable engineered to meet the stringent demands of industrial applications requiring reliable power transmission under challenging conditions. This cable represents a significant advancement in cable technology, incorporating multiple protective features that ensure consistent performance across diverse operational environments.

The cable's polyurethane (PUR) construction provides exceptional resistance to oil, UV radiation, and mechanical stress, making it particularly suitable for outdoor installations and harsh industrial environments. The halogen-free design ensures safer operation by eliminating toxic gas emission risks during fire incidents, while the flame-retardant properties according to IEC 60332-1-2 standards provide additional safety assurance.

One of the most notable characteristics of the NSHTÖU cable is its ability to operate effectively in outdoor environments and withstand short-term industrial water immersion for periods up to two weeks without interruption. This capability significantly expands its application range, allowing for use in washing stations, wet processing areas, and environments where temporary water exposure is unavoidable.

The cable maintains its flexibility and performance characteristics across a wide temperature range, ensuring reliable operation from -25°C to +80°C during flexible use. This temperature tolerance makes it suitable for both cold storage facilities and high-temperature industrial processes, providing versatility that reduces inventory complexity for facility managers.

Unique Design Features

Integrated Supporting Braid

The most distinctive feature of the NSHTÖU Crane PUR Cable is its integrated supporting braid embedded within the outer sheath. This innovative design element serves multiple critical functions that significantly enhance cable performance and longevity. The supporting braid prevents undesirable cable twisting during reeling and unreeling operations, eliminating the formation of corkscrew effects that can damage both the cable and connected equipment.

Traditional cables often suffer from torsional stress during continuous flexing operations, leading to internal wire damage, insulation failure, and reduced service life. The integrated braid distributes mechanical stress evenly across the cable structure, maintaining proper conductor alignment and preventing the spiral deformation that commonly occurs in heavily used reelable applications.

This design innovation is particularly beneficial in crane operations, where cables must maintain their structural integrity while supporting both electrical transmission and mechanical loads. The braid acts as a mechanical backbone, allowing the cable to function effectively as a hawser, drum cable, or towing cable while simultaneously providing reliable electrical connectivity.

Flexible Reeling and Unreeling Capability

The NSHTÖU cable's design enables continuous reeling and unreeling operations without requiring fixed connections during operation. This capability is essential for dynamic applications where cables must move freely while maintaining electrical connectivity. The cable's construction allows for smooth operation across cable reels, drums, and guide systems without binding or jamming.

The flexible design accommodates the complex motion patterns typical of crane operations, conveyor systems, and mobile equipment. Unlike rigid cables that require careful handling and specific routing, the NSHTÖU maintains its performance characteristics even under continuous motion stress, reducing maintenance requirements and extending operational life.

Wide Core Configuration Range

The NSHTÖU cable is available in an extensive range of core configurations, from compact 4G4 mm² arrangements to high-capacity 30G2.5 mm² multi-core variants. This diversity allows engineers to select the precise configuration needed for specific applications, optimizing both performance and cost-effectiveness.

The core sizes range from 2.5 mm² to 95 mm², accommodating everything from control circuits to high-power motor connections. The availability of both 4-core and 5-core configurations, along with specialized multi-core options up to 30 conductors, provides flexibility for complex control systems and power distribution applications.

Technical Specifications

The NSHTÖU Crane PUR Cable operates at a voltage rating of 600/1000V with a test voltage of 4000V, providing substantial electrical safety margins for industrial applications. This voltage rating makes it suitable for most industrial power distribution and motor control applications while maintaining compatibility with standard electrical systems.

The conductor material consists of tinned copper fine-stranded wire conforming to VDE 0295 Class 5 and IEC 60228 Class 5 standards. This construction provides optimal flexibility while maintaining low electrical resistance and excellent current-carrying capacity. The tinning process protects the copper from corrosion and oxidation, ensuring long-term electrical performance even in harsh environments.

The core insulation utilizes rubber compound type 3GI3, specifically formulated to provide excellent electrical insulation properties while maintaining flexibility across the cable's operating temperature range. This insulation system works in conjunction with the outer sheath material to provide comprehensive protection against environmental factors.

The outer sheath employs rubber compound type 5GM3, engineered to provide superior resistance to oils, chemicals, UV radiation, and mechanical abrasion. This compound maintains its protective properties across the full temperature range while providing the flexibility necessary for continuous flexing operations.

Bending radius guidelines specify minimum bend radii that preserve cable integrity during installation and operation. For fixed installations, the minimum bending radius is typically 7.5 times the cable diameter, while flexible applications require consideration of 15 times the diameter to ensure adequate fatigue resistance.

The cable's construction includes precise dimensional tolerances and weight specifications that facilitate proper system design and support structure sizing. Outer diameters range from 18.4mm for the smallest 4G4 configuration to 51.2mm for the largest 4G95 variant, with corresponding weights from 440 kg/km to 5530 kg/km.
