If you are involved in container terminals, heavy logistics, or industrial automation in Indonesia, you may have heard of the (N)SHTOEU low voltage reeling cable. Designed for Electrified Rubber Tyred Gantry (E-RTG) cranes, this cable combines high mechanical flexibility with reliable power transmission and integrated fiber optics for data communication. But what sets it apart from other low voltage cables, and why is it considered the go-to solution for modern crane operations?
What is the (N)SHTOEU Reeling Cable and How is It Used?
The (N)SHTOEU cable is a flexible low voltage reeling cable primarily used for power supply on E-RTG cranes. Its design allows for:
Continuous reeling and unreeling under high mechanical stress
Integration of fiber optic elements for data and communication
Reliable operation in extreme environments, including temperature fluctuations from -40°C to +80°C
In Indonesia, major container terminals in ports like Tanjung Priok, Surabaya, and Belawan rely on these cables for efficient crane operations. The combination of electrical and optical capabilities ensures that power and data signals reach cranes without disruption, even under continuous motion.
How Does the Fiber Optic Element Improve Performance?
One unique feature of the (N)SHTOEU cable is its integrated fiber optic element, which supports high-speed data transmission. Depending on the fiber type:
Fiber Type | Attenuation | Bandwidth | Typical Use |
|---|---|---|---|
50/125 µm | <2.8 dB/km at 850 nm | >400 MHz | Short-range crane automation signals |
62.5/125 µm | <3.3 dB/km at 850 nm | >200 MHz | Medium-range communication |
E9/125 µm | <0.4 dB/km at 1550 nm | - | Long-range or high-bandwidth control systems |
This allows crane operators to monitor and control E-RTG cranes in real time, reducing downtime and improving operational safety. The split earth conductor ensures electromagnetic interference does not affect data transmission.
How Does (N)SHTOEU Compare to Other Reeling Cables?
When selecting a reeling cable, engineers often compare mechanical flexibility, electrical performance, and additional features. Here’s a comparison of (N)SHTOEU vs. a generic low voltage reeling cable:
Feature | (N)SHTOEU | Standard Low Voltage Reeling Cable |
|---|---|---|
Mechanical Flexibility | High, class 5 conductor, polyester reinforcement | Medium, less flexible conductor |
Fiber Optic Integration | Yes, 12 fibers for data transmission | No |
Temperature Range | -40°C to +80°C | -20°C to +70°C |
Fire & Oil Resistance | IEC 60332-1, EN 60811-404 | Limited or optional |
Suitable for E-RTG Cranes | Yes | Limited |
Expected Lifespan | Long, >10 years under heavy use | Moderate, 5–7 years |
As this table shows, the (N)SHTOEU cable excels in high-stress, long-term operations compared to generic options.
