Type 506 / Type 512 / Type 518 / Type 524 for control connections inside large mining machines and interconnection between surrounding machine segments
Type 506 / Type 512 / Type 518 / Type 524 mining cable is specified in the supplied BS 6708 datasheet for control connections inside large mining machines and interconnection between surrounding machine segments. This page keeps the source-listed voltage, test reference, core functions and dimensional tables together so a procurement engineer can compare the requested model against the cable marking and the equipment connection. The editorial focus is the auxiliary-control function rather than the primary power path, not a generic promise of performance.
The supplied construction uses multiple individually screened cores laid in contact with flexible galvanized steel armour between inner and outer sheaths, with EPR or TPE insulation and a heavy-duty chloroprene jacket. That arrangement matters because This family is intended for control and interconnection duties; it should not be presented as a primary high-current power cable. The family should therefore be selected by model, core function and installation route as well as by voltage. The mining and tunnelling cable range provides the wider TEBAOFLEX product context.
- Choose by: confirm core count, circuit function, screen termination and whether the cable is carrying control/auxiliary circuits rather than machine power.
- Confirm before ordering: existing sheath marking, conductor area, cable length, route, support or handling system, terminations and the required inspection documents.
- Do not infer: values not listed in the supplied PDF, such as a different current basis, water/oil/UV performance, certification scope or mechanical interchangeability.
For machine interconnection projects, pair this control-cable data with the Mining & Tunnelling solutions page so the control route and primary power route are reviewed as separate requirements.
For a technical quotation, send the equipment nameplate or existing cable marking, voltage and size requirement, installation conditions, quantity, destination and any project-specific test or documentation requirement.
Type 506 / Type 512 / Type 518 / Type 524 construction
The cross-section below is the supplied construction drawing for Type 506 / Type 512 / Type 518 / Type 524. The ordering decision is driven by This family is intended for control and interconnection duties; it should not be presented as a primary high-current power cable.

Source-listed construction
| Construction element | Source-listed value |
|---|---|
| Conductor | Electrolytic stranded tinned copper wire, IEC 60228 Class 5 |
| Insulation | EPR or TPE insulation |
| Screen | Tinned copper and nylon braided screen over cores |
| Lay-up | All cores laid up in contact with each other |
| Armour | Galvanized steel pliable armour |
| Sheath | Heavy-duty chloroprene outer sheath |
| Cable design | Composite individual screens with pliable armour between inner and outer sheaths |
Do not use the drawing as a substitute for the dimensional tables. Confirm the cable end preparation, screen and earth termination, armour bonding and machine interface with the equipment documentation before installation.
Type 506 / Type 512 / Type 518 / Type 524 applications

The supplied datasheet identifies this cable for control connections inside large mining machines and interconnection between surrounding machine segments. Google result patterns for the BS 6708 family also separate cables by equipment duty, voltage class, core function and whether the route is armoured, screened, flat or auxiliary. That is why this page keeps the Type 506 / Type 512 / Type 518 / Type 524 construction separate from nearby Type numbers.
- Primary duty: control connections inside large mining machines and interconnection between surrounding machine segments.
- Model boundary: This family is intended for control and interconnection duties; it should not be presented as a primary high-current power cable.
- Project check: match the cable marking, core map, voltage, termination, route geometry and handling method to the machine drawing.
- Environmental review: confirm the actual mine/quarry conditions and any authority, inspection or documentation requirements; do not infer a certification or material-resistance claim from the model number.
For primary low-voltage power rather than control interconnection, compare the Type 70/71 mining cable; the conductor purpose and termination schedule should decide the selection.
The cable should be released only after the equipment route, required length, conductor area, core functions and connection details are agreed. If the intended duty is different from the source-listed application, request an engineering review through the quotation process.
