(N)TMCGEH3S 6/10 kV Mining Trailing Cable

(N)TMCGEH3S cable for mobile mining power

TEBAOFLEX (N)TMCGEH3S is a 6/10 kV mining trailing cable for electrical connections that move with the machine. The reference configuration is 3 × 120 + 2 × 50 + 1 × 16 mm²: three power conductors, two protective-earth conductors and one ground-check conductor in the same cable. It gives procurement and maintenance teams a clear starting point for matching the power circuit, grounding arrangement and monitoring circuit to an existing installation.

The separate pilot core matters when reviewing a replacement. A cable with a 10 mm² pilot, a different earth arrangement or an added optical unit has a different construction, even when the power-core size and voltage look similar. Match the complete designation and circuit allocation before comparing quotations. The reference data in Specifications support preliminary selection; the agreed cable drawing and project operating conditions govern the final order.

• Ordering focus: retain the full 3 × 120 + 2 × 50 + 1 × 16 mm² designation on the enquiry.
• Equipment interface: check the power termination, earth connections and ground-monitoring circuit together.
• Movement review: identify trailing duty and any drum or guide arrangement before selecting the cable.
• Installation fit: verify cable diameter, connector entry, route clearance and thermal conditions as one system.

Construction

The (N)TMCGEH3S 3 × 120 + 2 × 50 + 1 × 16 mm² build uses three individually screened EPR power cores in a triangular lay-up. Two earth conductors and the insulated pilot occupy the spaces around the power cores, inside a reinforced assembly and orange TPU sheath.

The conductor screen, EPR insulation and insulation screen are applied and cross-linked in a coordinated triple-extrusion process. The metallic braid provides the individual phase screen; it is a separate component from the semiconductive insulation screen.

Applications

(N)TMCGEH3S cable is intended for mobile mining power connections exposed to repeated movement and abrasive ground contact. Its screened phases, separate earth conductors and ground-check core suit equipment layouts that require power supply and earth-continuity monitoring in one cable.

• Electric shovels and excavators: trailing supply between the distribution point and moving machine.
• Mining drills: mobile electrical feeds where the route and handling system accommodate the cable.
• Draglines, dredges and material-handling equipment: installations requiring flexible medium-voltage power and a pilot circuit.

Match the cable to the movement

Describe whether the cable trails along the ground, passes over guides or winds onto a powered reel. For reel-fed use, review drum geometry, tension, travel speed, reverse bending and the number of layers before accepting a construction. A trailing-cable designation alone does not establish a reeling speed or flex-cycle rating.

Keep the route clear of vehicle crossings and crushing points. Check connector size and pilot-circuit compatibility as well as voltage and phase cross-section. The ground-check conductor carries the monitoring circuit; the earth conductors provide the protective-earth path.

(N)TMCGEH3S specifications

The featured construction is the 6/10 kV, 3 × 120 + 2 × 50 + 1 × 16 mm² cable described above. The size-series data below are published reference-design values for preliminary comparison; confirm the final dimensions and operating limits on the agreed TEBAOFLEX quotation and drawing.

Reference operating and test envelope

Reference dimensions, weight and electrical data

All configurations below use a 16 mm² pilot. Cross-sections are in mm². These values must be read as complete rows for their respective construction.

Current-rating conditions: continuous operation, free in air at 30 °C ambient, three loaded cores, DC or 50–60 Hz AC. Apply the appropriate installation corrections; these figures are not wound-on-drum current ratings.

120 mm² reference-design detail

Do not transfer diameter, weight or current values from a 10 mm² pilot version, LED variant or different jacket construction. Establish the required bend radius, pulling arrangement, connector entry and load current together before manufacture.

Standards

The following construction and test references support the specification of this (N)TMCGEH3S cable. State the required editions and inspection documentation in the purchase specification.

The official IEC 60228 scope explains the conductor sizes, wire requirements and resistance criteria covered by the standard.

Inspection information for the order

Specify the conductor-resistance results, power-core and pilot-core voltage tests, dimensional checks and sheath test records required for acceptance. Test voltage is separate from service voltage; agree the test duration and circuit connections in the inspection plan.
