CURRENT CARRYING CAPACITY

In Indonesia, the maritime, mining, and industrial sectors demand reliable submersible cables for operations under harsh conditions. Among the options, (N)TSCGEWÖU 8.7/15kV and 12/20kV submersible cables have emerged as top performers, offering flexibility, high voltage capacity, and water resistance. But what exactly makes these cables suitable for submerged applications like pumps, dredges, and floating docks?

What Are the Key Structural Features of (N)TSCGEWÖU Submersible Cables?

The (N)TSCGEWÖU cables are specifically engineered for permanent immersion in saline and brackish water up to 300 meters, while handling high mechanical stress. Their construction ensures durability, safety, and long-term performance.

1. Conductors:

  • Phase and earth conductors are made from Class 5 tinned copper, offering excellent flexibility and corrosion resistance in wet environments.

2. Insulation:

  • A high-quality rubber compound insulates the conductors.

  • Semi-conductive layers (tape and inner/outer layers) provide electrical stability and reduce dielectric stress.

3. Fillers and Sheaths:

  • Central filler: semi-conductive compound on a polyester textile support for mechanical stability.

  • Inner sheath: EPR rubber compound, providing waterproofing.

  • Outer sheath: CM rubber compound, resistant to water, chemicals, and abrasion.

4. Sheath Color:

  • Black for easy identification in industrial and underwater environments.

5. Compliance Standards:

  • VDE 0250 Part 813, HD 22.16, VDE 0295, EN 60228, IEC/EN 60332-1-2 flame retardant.

This robust design ensures the cable maintains mechanical integrity and electrical performance even under challenging underwater conditions.

What Applications Are These Submersible Cables Suitable For?

(N)TSCGEWÖU cables are designed for diverse underwater and industrial applications:

  1. Submersible Pumps:

    • Ideal for brackish and saltwater pumps in ports and coastal industrial plants.

    • Permanent immersion is possible up to 300 meters depth.

  2. Dredging Operations:

    • Handles mechanical stress and repeated bending during dredging.

    • Suitable for offshore and river dredges in Indonesia’s mining and construction sectors.

  3. Floating Docks & Marinas:

    • Provides stable electrical supply for lighting, winches, and docking equipment.

  4. Mining Applications:

    • Can support trailing operations of open-cast mining machinery in wet environments.

  5. Indoor and Outdoor Industrial Use: Resistant to UV, chemicals, and abrasion;Suitable for factories, power stations, and heavy-duty outdoor installations.

Case in Indonesia:
At a major dredging project in Jakarta Bay, 12/20kV (N)TSCGEWÖU cables were deployed to power submersible dredges. They operated continuously in brackish water, withstanding mechanical stress and temperature fluctuations, resulting in zero cable failures during the first 12 months of operation.


FAQ:

1. Can (N)TSCGEWÖU cables be used in both saltwater and freshwater?
Yes. Their rubber insulation and tinned copper conductors make them suitable for saline and brackish water, providing corrosion resistance and long-term performance.

2. What is the difference between fixed and flexed installation?

  • Fixed: Cable remains stationary, e.g., laid on the dock floor or permanently installed on a pump.

  • Flexed: Cable moves frequently, e.g., trailing dredge or floating pump operations. Flexed installations require larger bending radii.

3. How should these cables be installed for optimal lifespan?

  • Avoid sharp bends; maintain minimum bending radius (6× overall diameter fixed, 10× flexed).

  • Ensure proper strain relief at endpoints.

  • Avoid dragging on abrasive surfaces.

  • Periodically inspect the outer sheath for wear.

4. What is the typical lifespan of (N)TSCGEWÖU cables in submerged operations?
With correct installation and environmental conditions, 15–20 years of service life is achievable.

5. How do I select the right cable size for my equipment?
Consider voltage rating, power requirement, length of cable, and installation method. Refer to the nominal cross-sectional area, current-carrying capacity, and voltage drop tables provided by the manufacturer.

6. Can these cables be spliced or repaired underwater?
Splicing underwater is not recommended due to safety risks and water ingress. Repairs should be performed in dry conditions with proper sealing.


What Installation Tips Ensure Maximum Performance?

  • Use proper reels and supports to minimize bending and abrasion.

  • Avoid exceeding tensile load limits during installation.

  • Check environmental conditions, especially water temperature and chemical exposure.

  • Label cables clearly to avoid misconnection in multi-cable operations.

  • Follow local safety standards (IEC, VDE, EN, and Indonesian regulations).
