Présentation du produit

Type 307 for excavating, crushing and coal-cutting equipment

Type 307 mining cable is specified in the supplied BS 6708 datasheet for excavating, crushing and coal-cutting equipment. 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 unscreened-pilot 3.3 kV coal-cutter configuration, not a generic promise of performance.

The supplied construction uses three copper/nylon screened phase cores, one unscreened pilot core and a bare copper earth conductor, laid up together and covered by a heavy-duty chloroprene sheath. That arrangement matters because Type 307 has an unscreened single pilot; Type 307M screens the pilot and Type 307S uses an unscreened three-core pilot unit. The family should therefore be selected by model, core function and installation route as well as by voltage. The gamme de câbles pour l'exploitation minière et le creusement de tunnels provides the wider TEBAOFLEX product context.

  • Choisir par : confirm the existing pilot arrangement, phase area, cable handling route and 1900/3300 V equipment interface.
  • Confirmez avant de commander : 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.

Le BS 6708 mining cable replacement guide gives procurement teams a concise way to compare the Type 307 pilot and screening variants before selecting a 3.3 kV route.

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.

Construction

Type 307 construction

The cross-section below is the supplied construction drawing for Type 307. The ordering decision is driven by Type 307 has an unscreened single pilot; Type 307M screens the pilot and Type 307S uses an unscreened three-core pilot unit.

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.

Applications

Type 307 applications

The supplied datasheet identifies this cable for excavating, crushing and coal-cutting equipment. 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 307 construction separate from nearby Type numbers.

  • Primary duty: excavating, crushing and coal-cutting equipment.
  • Model boundary: Type 307 has an unscreened single pilot; Type 307M screens the pilot and Type 307S uses an unscreened three-core pilot unit.
  • 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.

If the pilot-screen requirement changes, use the Type 307M screened-pilot cable as the close model comparison and verify the monitoring circuit before procurement.

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.
