Designed to endure extreme mechanical stresses—including high-speed vertical reeling, repeated bending, torsional loads, and roller churning—this cable is ideal for use in demanding environments such as port operations, shipyards, and heavy material handling.
Key Construction Features
Robust Conductor: Crafted with very finely stranded, tinned copper (Class FS), the conductor offers exceptionally low resistance and high conductivity for efficient power transmission.
Advanced Core Insulation: The core is insulated with ethylene tetrafluoroethylene (ETFE), laid up in a maximum of three layers, and supported centrally by an aramid support element. This construction significantly increases the cable’s permissible tensile force.
Screening and Control: An individual screen made of tinned copper braid provides 60% coverage (with TSP 80%), ensuring that the control cores maintain low electromagnetic interference (EMI) and reliable signal integrity.
Protective Sheathing: The cable is encased in an inner sheath of polychloroprene (PCP) rubber (PROTOFIRM with a special compound >5GM5) and further protected by an outer sheath of the same high-grade material. This dual-layered sheath guarantees outstanding resistance to oil, UV radiation, ozone, and seawater, making it ideal for marine and industrial applications.
