The Suez Canal port modernization project presented unique engineering challenges that demanded exceptional cable performance characteristics. Operating in one of the world's most demanding marine environments, the terminal infrastructure must contend with extreme conditions that would quickly degrade conventional cable systems.

The client's primary requirement centered on sourcing long-life reeling cable systems specifically engineered for RTG crane applications. These cables needed to demonstrate superior resistance to ultraviolet radiation from intense Middle Eastern sunlight, torsional stress from rotational crane movements, persistent salt mist exposure that accelerates corrosion, oil contamination from hydraulic systems, and severe mechanical stress from millions of flexing cycles.

The project demanded a custom-engineered solution meticulously tailored to the port's specific cable reel configurations and festoon system requirements. Unlike standard industrial cables, port crane applications require specialized designs that can accommodate the complex three-dimensional movements inherent in container handling operations while maintaining consistent electrical performance throughout extended duty cycles.

RTG cranes present particularly challenging requirements, as these massive machines must seamlessly transition between stationary power connection points and mobile operational positions across the container yard. The reeling cable system serves as the critical link that enables this mobility while ensuring uninterrupted power delivery and control signal transmission.

Our engineering team conducted comprehensive analysis of the operational environment, including ambient temperature variations, humidity levels, wind loading, mechanical stress patterns, and electrical performance requirements. This detailed assessment formed the foundation for developing a cable specification that would not only meet immediate performance needs but also provide exceptional service life and reliability under the most demanding conditions.

Model Evolution: From Early Proposals to G-300716GPG-M&R-RTGS Finalization

The development of our final cable solution involved an extensive iterative design process that spanned several months of technical collaboration with the client's engineering team. During these comprehensive technical discussions, multiple cable configurations were systematically evaluated and refined to optimize performance for the specific application requirements.

Early design discussions explored specifications similar to established E-chain cable types that had proven successful in comparable applications. Initial proposals included configurations based on proven designs such as the CF310.UL.700.01 shielded single-core cable (1X70C) with a total required length of 1860 meters, which offered excellent electrical performance and mechanical durability for power transmission applications.

Additional early configurations examined included the CF900.05.222 multi-core control cable (18G2.5) with 1550 meters required length, which provided comprehensive control signal capability for crane automation systems. The CF35.UL.160.04 four-conductor power cable (4G16) with 620 meters length was also evaluated for its robust power delivery characteristics in marine environments.

Other design alternatives considered during the development phase included the CF310.500.01.UL shielded cable (1x50)C requiring 2790 meters, the CF35.60.04 shielded cable (4G6)C needing 620 meters, and the CF900.05.219 multi-pair signal cable 6X(2X0.5) with 1240 meters required. Each of these configurations brought specific advantages in terms of electrical performance, mechanical durability, or installation characteristics.

After extensive iterative design reviews, technical validation, and performance optimization, the G-300716GPG-M&R-RTGS model was finalized in May 2025 as the optimal solution for the Suez Canal application. This advanced cable design incorporated the best features from earlier proposals while addressing specific performance requirements unique to the port's operational environment.

The finalized G-300716GPG-M&R-RTGS design was specifically tailored to RTG crane applications, incorporating an integrated anti-torsion braid construction that effectively distributes rotational stress and prevents cable deformation during crane operation. The premium PUR (Polyurethane) sheath provides exceptional resistance to environmental factors while maintaining flexibility across extreme temperature ranges. The multi-core layout optimizes both power transmission and control signal capabilities within a single cable assembly.
