NTMTWOEU 600/1000 V Underground Mine Hoist Cable

NTMTWOEU 600/1000 V underground mine hoist cable

TEBAOFLEX NTMTWOEU is a flexible rubber-sheathed cable for suspended use on user-operated mine hoists in underground mining. The supplied application identifies control and telephone connections in a travelling mine-lift cable, where the arrangement needs more than a conventional fixed control cable: it needs a central support element and an anti-torsion construction suitable for the stated suspended duty.

The source information allows NTMTWOEU to operate as a self-supported cable at up to 200 m length with a 5× safety factor. That is a selection reference, not a substitute for the project hoist calculation. Confirm suspension geometry, cable mass, termination load, routing, drum or guide arrangement and site approval before the final design is released.

• Suitable for: stated suspended control and telephone connections on underground mine hoists or lifts.
• Reference configurations: supplied options from 8 × 2.5ST + 2 × 1FM(C) to 19 × 1.5(C)ST + 6 × (2 × 1FM)C.
• Confirm before ordering: core functions, suspended length, hoist interface, support method, route and required documentation.
• Choose another construction when: the application needs a fixed control cable, a power-only trailing cable or a different support/load design.

NTMTWOEU construction

The supplied NTMTWOEU build uses flexible control and communication conductors around a central steel support element. A textile anti-torsion braid and PCP rubber outer sheath complete the stated suspended mine-hoist construction.

Applications

NTMTWOEU is supplied for the stated use as a travelling or suspended cable for intrinsically safe control and telephone connections in user-operated underground mine hoists. This wording describes the intended control-system application; final circuit safety, equipment acceptance and installation responsibility remain project-specific.

Hoist-cable selection checks

• Confirm the core allocation for control, telephone or pilot functions against the hoist wiring schedule.
• Calculate suspended length, load path, support point and termination so the selected core configuration and cable mass suit the actual shaft arrangement.
• Use the supplied 200 m self-supported reference and 5× safety factor only after validating the specific hoist duty and applicable site requirements.
• Specify the required cable marking, inspection, test documentation and completed length before quotation.

TEBAOFLEX can review the existing NTMTWOEU marking and hoist wiring requirement before quotation, helping procurement teams separate a suspended control/telephone cable need from a standard mining power-cable request.

NTMTWOEU specifications

The following nominal configurations, dimensions and weights are transcribed from the supplied NTMTWOEU data. Confirm the final drawing and load calculation before order release.

Dimensions and weight

No bending radius, tensile-load value, test voltage, temperature range or individual core electrical data was supplied for these configurations. Confirm such requirements in the project specification rather than treating them as published NTMTWOEU ratings.

Standards

The supplied product information names the following standard references for NTMTWOEU.
