Type 245 Flexible Rubber Mining Cable 1.1–6.6 kV

Type 245 mining cable for longwall and continuous-miner service

This Type 245 mining cable is a flexible rubber cable family listed in the supplied datasheet for longwall shearers, continuous miners and peripheral longwall cable service. The family is organized by voltage and conductor area so a buyer can start with the machine supply requirement: Type 245.1 covers 1.1 kV, Type 245.3 covers 3.3 kV, and Type 245.6 covers 6.6 kV. The same page keeps those variants together while preserving their separate dimensional data.

The cable combines flexible tinned-copper conductors, EPR insulation, semiconductive screening, central extensible pilot conductors, interstitial earth conductors, open-weave reinforcement and a heavy-duty PCP sheath. The pilot arrangement is relevant where the cable system requires earth-continuity monitoring and control circuits, as stated in the source application note. See the mining and tunnelling cable range for adjacent cable families.

• Choose by: voltage variant, conductor area and the machine’s cable-service requirement.
• Confirm before ordering: existing cable marking, route, length, drum or guide arrangement, terminations and required documents.
• Important boundary: the supplied datasheet does not state a minimum bending radius, permitted tensile load or travel speed, so those values must be confirmed for the actual installation.

Type 245 mining cable construction

The Type 245 construction uses a flexible power-core arrangement with semiconductive layers, earth-continuity and control elements, textile reinforcement and a heavy-duty rubber sheath. The conductor screen is specified for cables rated 3.3 kV and above; the source does not state that screen for the 1.1 kV variant.

Layer arrangement

The supplied product image shows the black outer sheath, visible braid and exposed core arrangement. Final cable termination and the connection of pilot and earth functions must follow the equipment and protection design.

Type 245 mining cable applications

The supplied datasheet identifies Type 245 for longwall shearer cable service and also for continuous miners and peripheral longwall cable service. Its three central pilots are stated to support earth-continuity monitoring and control circuits.

• Longwall shearers: select the voltage variant and conductor area required by the machine supply.
• Continuous miners: confirm the existing cable marking, core functions and protection-system interface before cross-referencing.
• Peripheral longwall service: confirm route length, handling method, guide or drum arrangement and cable quantity.
• Mobile mine cable routes: the datasheet gives application and temperature limits but does not provide a minimum bend radius, tensile load or travel speed; obtain those values for the actual route before release.

For a quotation, provide the equipment nameplate or existing cable marking, voltage, conductor area, required length, installation route, terminations, inspection documents and any project-specific standard or marking requirement. Do not treat a Type 245 size-only match as proof of mechanical interchangeability.

Type 245 mining cable specifications

The following values are transcribed from the supplied Type 245 datasheet. The dimensional tables are separated by voltage variant because the insulation, screen and available conductor-area ranges differ. Confirm the final size, route and document requirements before quotation.

How to use the dimensional data

Use the voltage variant first, then check conductor area, nominal outer diameter and mass against the machine interface, cable supports and handling equipment. The source does not state current capacity, minimum bending radius, tensile load or travel speed; those items require project confirmation.
