XAT/EVA FO 35 kV Armoured Mining Cable

XAT/EVA FO cable is a 35 kV armoured power-and-fibre assembly for fixed feeder and substation connections. The configuration brings three copper phase conductors together with two grounding conductors, a separate ground-check conductor and 12 single-mode optical fibres. FA and AA+FA are alternative armour constructions within this electrical arrangement.

Each power core combines XLPE-TR insulation with extruded semiconductive layers and an individual copper-tape screen. Low-smoke, halogen-free filling, inner covering and an EVA outer sheath complete the assembled cable around its power, grounding and optical elements.

Select the armour before checking the route dimensions. AA+FA adds steel wires beneath two steel tapes; FA uses two steel tapes. The resulting differences in diameter, weight and bending radius affect support space, handling arrangements and the path into the equipment. The Specifications tables keep the final-position and installation bending limits separate for each construction.

For a quotation, identify the armour option and required length, and provide the feeder route, support arrangement and power, grounding, ground-check and optical termination requirements. Include the project optical-fibre specification and installation pulling requirements so these can be addressed with the cable selection.

Browse the mining and tunneling cable range for related duties. For route selection, consult the fixed armoured mining cable guide.

Construction

The two XAT/EVA FO constructions share three screened power cores, two bare grounding conductors, a separate yellow PE-insulated ground-check conductor and one optical unit containing 12 single-mode fibres. Their armour layers differ.

Select and identify the armour option in the order and end-connection drawing. Keep the phase screens, grounding conductors, ground-check circuit and optical fibres identifiable when planning termination.

Applications

XAT/EVA FO cable is intended for fixed power transmission and distribution connections to and from substations, including outdoor and underground industrial routes in dry or damp environments.

• Fixed mine feeder routes requiring medium-voltage power and integrated optical fibres.
• Supported cable routes between distribution equipment and substation connections.
• Installations where low-smoke, halogen-free coverings form part of the project specification.

Plan supports and handling around the selected construction's diameter, weight and bending limits. Use the installation radius while placing the cable and the final-position radius for its installed route. Define any pulling, elevation and termination requirements in the project drawing.

For equipment that drags or repeatedly reels its supply cable, select a cable construction intended for that movement duty.

Specifications

Dimensions and weights are nominal or approximate as indicated. Apply the bending limits for the selected armour; the final-position and installation values describe different stages of the route.

For selection, state the electrical system, cable length, installation method, optical-fibre requirements and the termination arrangement for each conductor and optical element.
