3.6/6kV to 18/30kV NTSCGEWOEU-W Cable
Overview: The TEBAOFLEX NTSCGEWOEU-W cable is a premium flexible medium-voltage power supply cable. Engineered based on DIN VDE 0250-813, it is explicitly designed to withstand extreme mechanical stresses in open-pit mining facilities and is fully rated for continuous operation in permanent water immersion.
Key Specifications:
- Voltage Range: 3.6/6 kV up to 18/30 kV.
- Environmental Resistance: Fully submersible in sewage, salt water, and brackish water.
- Core Design: 3 main conductors with protective earth conductors split into 3 in the outer interstices (…/3E design).
- Sheath Material: Heavy-duty Red 5GM3 rubber compound (Oil, UV, Ozone resistant).
- Application: Open-pit mining trailing, dredgers, floating docks, and submersible pumps.
The Premium NTSCGEWOEU-W Cable for Open-Pit Mining and Underwater Operations
Operating heavy machinery in open-pit mines or dynamic aquatic environments demands a power supply solution that refuses to fail. The TEBAOFLEX NTSCGEWOEU-W cable is an advanced, heavy-duty flexible medium-voltage cable engineered for exactly these extreme conditions. Unlike standard rubber cables, the “W” designation signifies its enhanced capability for permanent immersion in water, making it the ultimate lifeline for submersible pumps, floating docks, and severe industrial operations.
Why Choose the TEBAOFLEX NTSCGEWOEU-W Cable?
As an industry-leading source factory, TEBAOFLEX manufactures the NTSCGEWOEU-W cable strictly according to DIN VDE 0250 Part 813. This cable is built to handle incredibly high mechanical stresses, constant reeling, and severe abrasion typical in mining facilities. Moreover, its specialized inner and outer rubber sheaths allow it to operate continuously in challenging aquatic environments, including raw sewage, heavy salt water, and brackish water, without degrading.
Advanced Cable Construction (…/3E Design)
To ensure flawless power delivery and unparalleled safety (CPR 305/2011 compliant), our cable utilizes a highly specialized symmetrical construction:
- Main Conductors: Finely stranded tinned copper wires, class 5 (DIN EN/IEC 60228) to prevent oxidation.
- Electrical Field Control: Extruded inner and outer semi-conductive rubber stress control layers over the insulation to eliminate partial discharge.
- Insulation: Premium EPR (Ethylene Propylene Rubber) compound type 3G13.
- Protective Earth Conductor: Tinned copper wire spinning, symmetrically split into 3 in the outer interstices (…/3E configuration) to minimize electromagnetic interference.
- Inner Sheath: Synthetic EPR rubber compound based on type GM1b, specifically optimized for waterproofing and filling the interstices.
- Outer Sheath: Heavy-duty rubber compound type 5GM3. Highly resistant to oil (EN 60811-404), ozone, and UV rays. Standard color: Red.

Frequently Asked Questions (FAQ)
1. What does the “W” in NTSCGEWOEU-W signify?
In German cable nomenclature, the “W” specifically denotes enhanced suitability for water applications (Wasser). This means the NTSCGEWOEU-W cable is built with optimized GM1b and 5GM3 rubber compounds that actively resist water ingress, making it perfectly safe for permanent submersion in sea water, sewage, and brackish environments.
2. Can this cable be used on a reeling drum?
Yes. This cable is highly flexible and engineered to handle torsional stresses of +/- 100 °/m and a high tensile load of 15 N/mm². It is an excellent choice for trailing operations behind mobile open-pit mining equipment or winding on heavy-duty motorized reeling drums.
3. How do I request a custom length or different voltage rating?
As a leading industrial cable factory, TEBAOFLEX can manufacture this cable up to 18/30kV and in cross-sections up to 3x185mm². We welcome global wholesale inquiries and project-specific customizations. Please contact our mining solutions team for direct factory pricing and technical support.
