Introduction
Cables are the invisible lifelines of modern industry. In harsh and demanding environments such as open-pit mines, dredging operations, offshore platforms, and underwater pumping systems, the reliability of a power cable directly influences safety, productivity, and equipment performance. Among the most advanced solutions for these conditions are (N)TSCGECEWÖU submersible cables, rated for 8.7/15kV and 12/20kV applications.
These cables are engineered to operate under high mechanical stress, deep-water immersion up to 300 metres, and extreme temperature ranges. Their construction, based on tinned copper conductors, robust rubber insulation, and multiple layers of water-proofing sheaths, ensures durability, flexibility, and compliance with stringent standards such as VDE 0250 Part 813 and IEC/EN 60332-1-2 for flame retardancy.

Frequently Asked Questions (FAQ)
Q1: Can (N)TSCGECEWÖU cables be permanently submerged?
Yes. They are designed for continuous operation up to 300 metres underwater, in both salty and brackish water.
Q2: What makes these cables different from standard rubber-insulated cables?
Their multi-layered construction, semi-conductive shielding, and water-blocking compounds make them uniquely suited for high-voltage, submerged, and mechanically demanding environments.
Q3: How do they perform under reeling conditions?
They maintain high current capacity but derating occurs with multiple layers of reeling. Correct drum design and installation reduce losses.
Q4: Are they suitable for extreme climates?
Yes. With a fixed temperature range of –40°C to +80°C, they can operate in cold northern climates and hot desert mines.
Q5: Do they meet international safety standards?
Absolutely. They comply with VDE, EN, and IEC standards, including flame retardancy and conductor specifications.
The (N)TSCGECEWÖU 8.7/15kV and 12/20kV submersible cables are more than just high-voltage conductors—they are lifelines that enable safe and efficient operation in mining, dredging, offshore, and industrial applications. Their unique construction ensures waterproofing, flexibility, mechanical strength, and long-term durability in environments where failure is not an option.
As demonstrated in the South African case study, these cables not only ensure continuous operations but also improve safety and cost efficiency in industries where both are critical.
For organisations operating in demanding underwater or high-stress environments, investing in (N)TSCGECEWÖU submersible cables is not just a technical choice—it’s a strategic decision that safeguards people, equipment, and productivity.
