O2nGcekż/w-G(W) 3.6/6 kV Double-Screened Mining Cable

O2nGcekż/w-G(W) is a 3.6/6 kV flexible mining cable for trailing supplies to mobile mining and industrial machinery. Individual copper composite screens surround the EPR-insulated power cores, while a second, concentric copper screen surrounds the inner sheath. An ON5 inner sheath and ON4 outer sheath form the double polychloroprene construction. This arrangement must be specified as a complete cable system when replacing a screened trailing lead.

The family offers three distinct auxiliary arrangements. The pilot-free version has three screened power cores and distributed bare protective conductors. The three-pilot version places a pilot/earth unit in each outer interstice. The six-pilot version uses three screened pairs. The designations 4, 7 and 10 count the protective function as one; they are not a literal count of separate insulated cores. The final number in each configuration gives the nominal protective area, rather than the area of every individual earth element.

Select the full -G or -GW designation in the enquiry. The -GW construction adds tapes that swell in contact with moisture to restrict longitudinal water movement. This feature does not define an unlimited immersion rating. The tables separate the available core arrangements from configurations with stated cable diameters, helping match the cable to glands, connectors and handling equipment. TEBAOFLEX supplies this family from a 50 m minimum order, with a lead time of 7–45 working days. Include the voltage, power size, pilot arrangement, protective circuit, sealing option and actual trailing conditions for a matched quotation.

Where 3.6/6 kV underground mine distribution shifts from flexible trailing duty to fixed roadway, incline or shaft-zone installation requiring copper-tape core screens and galvanized round steel wire armour, see: YHKGYFoyn 3.6/6 kV Individually Screened Steel-Wire-Armoured Underground Mine Power Cable.

Construction

The double-screen system consists of individual power-core screens and a separate concentric screen over the inner sheath. Protective-conductor and pilot layouts change with the 4-, 7- or 10-functional-conductor construction; the main image shows the pilot-free 3 × 95 + 35 mm² base -G build.

Applications

Use the complete power, pilot, protective-conductor and screen arrangement to match the machine circuit and cable-handling conditions.

• Trailing power supply to mobile mining and industrial machines operating within the 3.6/6 kV rating.
• Heavy-duty routes where abrasion, tearing and oil exposure influence the choice of outer sheath.
• Machine connections requiring both individual power-core screens and a separate overall copper screen.
• Circuits needing no pilots, three pilots or three screened pilot pairs, using the corresponding protective-conductor layout.
• Routes requiring longitudinal water-blocking tapes, when the -GW option and termination sealing are explicitly specified.
• Replacement projects where cable diameter, protective-circuit continuity and screen terminations must match the machine and connectors.

For route and construction selection, see our mining and tunnelling cable solutions.

For a chain-handled coal-cutter connection, compare NTSKCGEcWÖU coal-cutter chain cable. Check its concentric control/protective-conductor arrangement and mechanical protection against the double-screen construction required here.

For a different three-power, earth-and-pilot trailing arrangement, review NTSKCGEWÖU 3.6/6 kV trailing cable. Match the protective circuits, pilot function and sheath system before selecting a replacement.

For fixed armoured feeder or control routes, see TECK90 600 V / 1 kV armoured control and power cable. This is a different installation duty; it is not a replacement for a moving trailing cable.

Specifications

Configuration areas are in mm². In the configuration notation, the first term identifies three power cores, any middle term identifies pilots, and the final term is the nominal protective area.

Functional conductor classes 4, 7 and 10 count the protective function once. They do not mean four, seven or ten individually insulated cores. In the pilot-free build, the earth conductors are distributed in three outer interstices.

The notation 3 × 2 × 4 means three pairs of 4 mm² pilots. It does not mean three 8 mm² pilot conductors.

Use only the listed discrete combinations. A power-size range does not make every pilot size and protective area interchangeable.

Overall dimensions are provided only for the listed rows. Confirm the finished diameter and tolerance for the selected -G or -GW construction before choosing glands, connectors and cable-handling hardware.

Specify the required current, duty cycle, ambient conditions and handling arrangement for rating selection. No universal current, reel speed, bend radius or pulling-tension value is assigned to all configurations on this page.

The 90°C limit refers to the conductor. Agree ambient and handling temperatures separately for the intended installation.

Water-swelling tapes in -GW limit longitudinal water movement. Fluid compatibility, immersion depth and duration, end sealing and entry protection require separate specification.

Coordinate the protective conductor, individual screens and overall-screen terminations with the machine protection and earthing system. Pilot cores do not replace the protective circuit.

Standards

Official standards and approval references

Conductor and compound references describe parts of the construction. They do not by themselves establish product approval for a particular mine or hazardous location.

Specify the required flame-test method, acceptance documents and standard editions with the enquiry. General flame-retardant characteristics do not establish circuit integrity in a fire.

• IEC 60228:2023 — Conductors of insulated cables — Official scope covering conductor cross-sectional areas, wire construction and resistance, including flexible copper conductors. The required conductor-standard edition must be agreed for the selected cable.

Certifications and document support

Review our company certificates and document scopes when identifying the documentation required for the quoted construction.

Provide the destination mine, full -G or -GW designation, voltage, power/pilot/protective arrangement and required approval or test documents. Identify the individual and overall-screen termination method, operating temperatures and handling duty so the quotation and supporting documents refer to the same construction.
