Key Features of PROTOLON(SC) (N)TSKWOEU-J Cable

Flexible Bare Copper Conductors

The foundation of any reliable low voltage rubber cable for ships lies in its conductor design. The PROTOLON(SC) cable features finely stranded bare copper conductors that provide exceptional flexibility while maintaining excellent electrical conductivity. This enhanced flexibility proves crucial during docking operations when cables must be maneuvered around dock equipment and connected to various vessel configurations. The stranded copper construction allows the cable to bend and flex without compromising the electrical connection, ensuring reliable power transfer even under mechanical stress.

The conductor design also facilitates easier handling by dock personnel, reducing installation time and minimizing the risk of damage during connection procedures. This flexibility becomes particularly valuable in challenging weather conditions where quick, efficient connections are essential for maintaining port operations.

EPR Insulation and Rubber Sheathing

The cable's insulation system utilizes high-quality EPR (Ethylene Propylene Rubber), renowned for its superior electrical and mechanical properties in marine applications. This weatherproof marine rubber cable for ship power supply incorporates dual-layer protection with both inner and outer rubber sheaths manufactured from vulcanized rubber compounds. The outer sheath provides exceptional resistance to oil, UV radiation, moisture, and abrasion – critical properties for equipment exposed to harsh marine environments.

This robust sheathing system ensures the cable maintains its integrity during prolonged exposure to saltwater spray, extreme temperatures, and mechanical wear. The oil-resistant properties prove particularly valuable in port environments where hydraulic fluids and fuel spills are common occurrences. Additionally, the UV-resistant formulation prevents degradation from constant sun exposure, extending the cable's operational lifespan significantly.

Three-Core Symmetrical Design

One of the standout features of this 0.6/1kV ship power cable is its symmetrical three-core configuration, specifically engineered to minimize electromagnetic interference (EMC). This low EMC ship-to-shore power cable 0.6/1kV design ensures that sensitive electronic equipment aboard vessels remains unaffected by electrical noise during power transfer operations.

The symmetrical arrangement of conductors creates a balanced electromagnetic field, reducing the potential for interference with navigation systems, communication equipment, and other critical shipboard electronics. This feature becomes increasingly important as vessels incorporate more sophisticated digital systems that require clean, stable power sources.

Integrated Control Cores

Beyond power transmission, the PROTOLON(SC) cable incorporates dedicated control cores that enable advanced functionality in modern shore connection systems. This control-core marine cable for flexible ship connections supports automated power management systems, remote monitoring, and safety interlocks that ensure secure power transfer operations.

The control cores facilitate communication between shore-based power management systems and shipboard equipment, enabling features such as automatic voltage matching, load monitoring, and emergency disconnect functions. This capability allows the cable to adapt to different vessel types and their unique power control requirements, from cargo ships to cruise liners to naval vessels.

Broad Temperature Range

Marine environments present extreme temperature challenges, from arctic ports to tropical harbors. The PROTOLON(SC) cable operates reliably across a temperature range from -40°C to +80°C in fixed installations and -25°C to +80°C during flexible operation. This broad temperature tolerance ensures consistent performance regardless of geographical location or seasonal variations.

The cable can withstand maximum operating temperatures of 90°C and short-circuit conditions up to 250°C, providing safety margins that exceed typical operating requirements. This thermal performance makes it suitable for deployment in the most demanding marine environments worldwide.

Flame Retardant and Safety-Driven Design

Safety remains paramount in marine applications, where fire risks pose significant threats to vessels and port facilities. The PROTOLON(SC) cable meets stringent flame propagation standards according to DIN EN 60332-1-2, ensuring it will not contribute to fire spread in emergency situations. The flame-retardant properties provide crucial time for evacuation procedures and fire suppression efforts.

The cable's construction also includes features that enhance overall system safety, including protection against electrical faults and mechanical damage that could compromise vessel or port safety.
