Type 307S BS 6708 1900/3300 V Three-Core Pilot Coal Cutter Cable

Type 307S for excavating, crushing and coal-cutting equipment

Type 307S 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 three-core pilot-unit option for 3.3 kV face equipment, not a generic promise of performance.

The supplied construction uses three copper/nylon screened phase cores, one unscreened pilot unit with three thinner cores and a bare earth conductor, laid up together under a heavy-duty chloroprene sheath. That arrangement matters because Type 307S uses an unscreened three-core pilot unit, making its control-core arrangement distinct from both Type 307 and Type 307M. 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 the three-core pilot unit and the separate pilot test requirement before matching the cable to the machine control system.
• 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 a three-core pilot specification, use the BS 6708 mining cable replacement guide to check the differences between the Type 307 family variants before approving a substitute.

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 307S construction

The cross-section below is the supplied construction drawing for Type 307S. The ordering decision is driven by Type 307S uses an unscreened three-core pilot unit, making its control-core arrangement distinct from both Type 307 and Type 307M.

Source-listed construction

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 307S 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 307S construction separate from nearby Type numbers.

• Primary duty: excavating, crushing and coal-cutting equipment.
• Model boundary: Type 307S uses an unscreened three-core pilot unit, making its control-core arrangement distinct from both Type 307 and Type 307M.
• 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 a single unscreened pilot construction, the Type 307 coal cutter cable is the adjacent reference; pilot function must be confirmed from the cable schedule.

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.

Type 307S specifications

The summary below identifies the supplied model family. The source-transcribed tables that follow retain the PDF's dimensional, electrical and construction values, including available sizes, resistance, current, diameter, mass, bending or pulling data when the PDF provides them.

Complete source-transcribed technical tables

Source PDF: BS6708_TYPE_307S_1900_3300V_POWER_SUPPLY_CABLE_datasheet.pdf; 3 pages; 4 extracted tables. Values are not recalculated or replaced by third-party values.

Use the table values with the equipment drawing and approved termination plan. If the requested conductor area, current basis, mechanical limit or environmental condition is not listed in the supplied PDF, treat it as a quotation-stage confirmation item.

Type 307S standards and references

The product page preserves the BS 6708 reference appearing in the supplied PDF. The BSI record currently identifies BS 6708:1998 as withdrawn on 22 May 2026; this status note is a standards-reference update, not a claim that the product is currently certified or approved. See the official BSI BS 6708 scope record for the published status.

For an RFQ, state the required standard documents, inspection scope, test report, cable marking, destination rules and any replacement-equivalence requirement. The model number alone does not establish legal installation compliance.
