Type (N)SHTOEU 0.6/1KV – Innovative Reeling Cable for E-RTG Power Distribution
Designed to Withstand Severe Mechanical and Environmental Stress with Integrated Fibre-Optic Data for Modern Port Automation
CORDAFLEX XPRT (N)SHTOEU cable is an advanced, flexible low voltage reeling cable engineered specifically for the demanding power supply requirements of Electrified Rubber Tyred Gantry (E-RTG) cranes and similar mobile industrial systems.
Designed to excel under high and very high mechanical stresses, this cable not only ensures reliable electrical performance but also offers optional integrated fiber-optic data transmission for real-time monitoring and automation in port and shipyard environments.
Key Technical Attributes and Construction
This cable is constructed with very finely stranded, tinned copper (Class FS) conductors, which provide exceptionally low electrical resistance and enhanced conductivity. It features a three-core design with a split earth conductor that ensures balanced power distribution and minimizes interference.
Where required, an integrated optical element is placed within the interstices; this consists of six optical tubes, each capable of housing one to four optical fibers, enabling high-speed data communication alongside power delivery.
The core insulation is manufactured from premium EPR rubber (PROTOLON MS), enhanced with a special compound (>3GI3) for superior dielectric strength and durability. The cable’s protective structure includes an inner sheath made from high-quality polychloroprene (PCP) (PROTOFIRM with a compound >5GM5), and a matching outer sheath that offers excellent resistance to oil, UV radiation, ozone, and seawater.
In addition, polyester braiding reinforcement significantly increases its mechanical strength, ensuring the cable can withstand repeated roller bending, reversed bending, and torsional stress.
