DIMENSIONS

Submersible high-voltage cables are critical components in industries where water, mechanical stress, and flexible operation are daily challenges. Among them, the (N)TSCGECEWÖU 8.7/15kV and 12/20kV submersible cables stand out for their durability, flexibility, and suitability for harsh environments such as pumps, dredges, floating docks, and open-cast mining equipment.

What Are the Key Features of (N)TSCGECEWÖU Submersible Cable?

The (N)TSCGECEWÖU series is designed to provide flexible high-voltage connections under water, including saline and brackish environments, up to depths of 300 meters. Key characteristics include:

  • Voltage Ratings: 8.7/15kV and 12/20kV

  • Test Voltages: 24kV for 8.7/15kV, 29kV for 12/20kV

  • Ambient Temperature:

    • Fixed: -40°C to +80°C

    • Flexed: -25°C to +60°C

  • Minimum Bending Radius:

    • Fixed: 6 × overall diameter

    • Flexed: 10 × overall diameter

  • Submersibility: Permanent immersion up to 300m

These features make it ideal for trailing operations in open-cast mining, as well as submerged pump and dredge installations, where mechanical stress, bending, and water exposure are constant factors.

In Which Industries and Applications Is the (N)TSCGECEWÖU Cable Used?

The versatility of the (N)TSCGECEWÖU cable makes it suitable for:

  1. Submersible Pumps: For irrigation, municipal water, and industrial pumping stations.

  2. Dredging Equipment: High flexibility allows trailing operations for excavation in rivers, ports, and offshore.

  3. Mining Equipment: Trailing high-voltage supply to excavators, conveyors, and mobile equipment.

  4. Floating Docks & Marine Installations: Resistant to saline water immersion, UV, and mechanical stress.

Case – Indonesia:
In the Sumatra tin mining project, 12/20kV (N)TSCGECEWÖU cables were installed on trailing mining excavators in brackish water conditions. Operators reported reduced downtime due to cable failure and improved safety due to the tinned copper conductors resisting corrosion.

Frequently Asked Questions (FAQ)

Can (N)TSCGECEWÖU Cables Be Used in Saltwater Environments?

Yes. The tinned copper conductors and CM rubber outer sheath make the cable resistant to corrosion from saltwater, allowing permanent immersion up to 300 meters.

What Is the Maximum Load Current for 50mm² Cable?

For 50mm², the current capacity is 216A when laid on the floor and 173A when reeled, assuming ambient temperature of 30°C.

How Does (N)TSCGECEWÖU Compare With XLPE Submersible Cables?

While XLPE offers good electrical insulation, it is less flexible, making it harder to handle in trailing or dredging operations. (N)TSCGECEWÖU offers higher flexibility, better mechanical stress resistance, and longer immersion capability.

What Are the Typical Failures and How to Prevent Them?

Common failures include abrasion, bending fatigue, and water ingress at terminations. Prevention involves proper bending radius, protective guides, and high-quality waterproof terminations.

Is This Cable Suitable for Trailing Mining Equipment?

Absolutely. The flexible construction, high tensile load, and submersibility make it ideal for trailing conveyors, mobile excavators, and dredges in mining environments.
