This cable is a mining-grade power cable designed for supplying electrical power to underground mining machines (such as continuous miners).
It is built to withstand harsh conditions, with robust insulation, flame and oil resistance, and mechanical protection provided by a specialized armor.
The design complies with several European and German standards (e.g., DIN VDE 0250, DIN VDE 0207, EN 60228).
Construction Details
1. Conductors
Working Cores:
Made from flexible, multi-stranded tinned copper wires (Class 5 per EN 60228).
May have a semi‐conductive tape applied directly on the conductor for additional performance.
2. Insulation and Screening
Insulation Material:
Uses Ethylene Propylene Rubber (EPR) of type 3GI3, following DIN VDE 0207 Part 20.
Screening:
Both under and on the insulation, extruded semi‐conductive rubber screens are applied.
Color Coding:
Working cores are left in a natural color with numbered identification (1, 2, 3).
Auxiliary cores are marked in brown, black, and gray.
3. Auxiliary and Protective Elements
Auxiliary/Protective Cores:
Consist of 1.5 mm² conductors insulated with EPR.
They are twisted together with tinned copper wires to form a protective core, then covered by a semi‐conductive rubber layer.
Core Assembly:
The three insulated and screened working conductors are twisted together.
The auxiliary/protective cores are placed in grooves alongside the working cores.
A polyester film separator may be added in the cable’s center for additional organization.
4. Sheaths and Armor
Inner Sheath:
Made of EPR rubber (type GM1b) according to DIN VDE 0207 Part 21.
Armor:
Constructed from twisted steel-copper wires (per WT SM/025/0005a, Edition 2) to provide mechanical protection.
The twist angle of the armor lies between 34° and 400°.
Combined copper and steel wires form a concentric grounding element with a 6 mm² cross-section.
Outer Jacket:
Made of poly(chloroprene) (Type 5GM5 per DIN VDE 0207 Part 21) in a bright red color for easy identification.
Characteristics
Oil Resistance:
Meets requirements specified in DIN VDE 0473 Part 811-2-1.
Flame Propagation Resistance:
Complies with DIN VDE 0482-332-1-2 and PN-EN 60332-1-2.
Temperature Range:
Designed for use in environments ranging from –30°C to +90°C.
Packaging:
Typically supplied in 250‑meter lengths on drums; other packaging options are available on request.
Additional Information
Mechanical Protection:
The steel-copper wire armor protects the cable from mechanical damage.
Durability:
The cable is highly resistant to flame spread, abrasion, tearing, ozone, and UV radiation.
Identification:
Clear markings on the outer jacket help with quick identification in the field.

FAQs
What is the primary application of this cable?
This cable is engineered for underground mining operations. It is used to power mining machines—such as continuous miners—in environments where durability and safety are paramount.
What are the voltage ratings and configurations available?
The cable is rated at 3.6/6 kV. Its configuration (indicated as 3x…+3x(1.5STKON+…/3KON)+6UL KON) is designed to meet high-demand power applications in mining operations.
What type of conductors does the cable use?
It employs flexible, multi-stranded tinned copper conductors (class 5 according to EN 60228) that provide excellent conductivity and flexibility under mechanical stress.
What insulation and screening materials are utilized?
The cable features insulation made of Ethylene Propylene Rubber (EPR, type 3GI3) along with extruded semi‑conductive rubber screens both under and on the insulation. This combination enhances electrical performance and environmental protection.
How does the cable protect against mechanical damage?
A robust armor, constructed from twisted steel-copper wires, surrounds the inner components. This armor offers high resistance to impacts, abrasion, and tearing—crucial in the rough conditions typical of underground mining.
What environmental resistances does the cable offer?
It is designed to resist oil (per DIN VDE 0473), flame propagation (DIN VDE 0482-332-1-2/PN‑EN 60332-1-2), ozone, and UV exposure, ensuring reliable performance in harsh environments.
Which standards does this cable comply with?
The cable is manufactured in accordance with European and German standards, including DIN VDE 0250, DIN VDE 0207 (for insulation and inner sheath), and EN 60228 (for conductor quality).
How is electrical safety ensured during fault conditions?
A concentric grounding element is integrated into the cable design. This is formed by twisted copper and steel wires, which helps safely channel fault currents and improves overall system protection during short-circuit conditions.
What are the installation advantages of this cable in mining settings?
Its design features a minimum bending radius of approximately 2.3 times the cable’s diameter, allowing for easier installation in confined or complex underground layouts. Additionally, clear markings on the outer jacket facilitate quick identification during installation and maintenance.
Can this cable be applied in other industrial settings beyond mining?
Although it is optimized for the demanding conditions of underground mining, the cable’s robust mechanical protection and resistance to flame, oil, ozone, and UV make it suitable for other heavy-duty industrial applications where similar challenges exist.
