SPREADERFLEX XTRM (N)SHT11Y cable is a next-generation, low voltage reeling cable engineered to excel in applications where vertical reeling operations demand exceptional durability and reliability.
Specifically designed for use in spreader basket systems on mobile harbour cranes, this cable meets the rigorous requirements of extreme mechanical stress and harsh operating conditions found in port and shipbuilding environments.
Key Features and Advantages
High Mechanical Resilience:
Built to endure extreme bending, torsional loads, and roller churning, this cable is optimized for vertical reeling. Its robust construction supports repeated dynamic movements without compromising structural integrity.
Superior Conductor Performance:
The cable features extremely finely stranded, bare copper (Class FS) conductors that offer minimal electrical resistance and high conductivity. These conductors are arranged in a two-layer system: the first layer consists of 5 preassembled elements (including a CAN-BUS pair), and the second layer comprises 22 cores of 2.5 mm diameter, ensuring precise core identification with black insulation and light printed numbers and a green-yellow earth conductor.
Advanced Insulation and Sheathing:
Utilizing ethylene tetrafluoroethylene (ETFE) for core insulation, the cable benefits from excellent dielectric properties and resistance to environmental degradation. The insulation is laid up in two layers to further enhance performance. An inner and outer sheath made of high-quality polyurethane (PUR)—with a proprietary compound—provides outstanding protection against oil, UV radiation, ozone, and seawater. This makes the cable ideal for permanent water immersion and operation in cold environments.
Enhanced Structural Support:
A central aramid support element significantly increases the cable’s tensile strength, offering a breaking load of up to 20,000N. This design ensures a safety factor of 5 when the cable is suspended vertically for heights of up to 50 meters.
Optimized Electrical Specifications:
With a rated voltage of 0.6/1KV (up to 1.2KV maximum) and a nominal voltage of 1000V, the cable undergoes rigorous testing at 3.5KV. It is capable of maintaining continuous operation at temperatures up to 90°C, withstanding short-circuit conditions up to 250°C.
Environmental and Thermal Robustness:
The cable is designed to operate in ambient temperatures ranging from -50°C to +80°C in fixed installations and -35°C to +80°C for flexible applications. It is also flame retardant (in accordance with EN/IEC 60332-1-2), ensuring high levels of safety.
Low EMI and Integrated Control:
Its symmetrical three-core design and precise manufacturing tolerances ensure extremely low electromagnetic interference (EMI). For enhanced functionality, the cable may include an integrated CAN-BUS pair to support control and communication in modern automated systems.
Operational Efficiency in Vertical Reeling:
Engineered for vertical reeling operations, the cable supports a maximum hoist travel speed of 160 m/min and a maximum lifting height of 90 m. The recommended bending radii are 4×D for fixed installations, 5×D for flexible operations, and 20×D for S-type directional changes, where D represents the cable’s diameter.
