Type 307M BS 6708 1900/3300 V Screened Pilot Coal Cutter Cable

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

Type 307M 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 fully screened pilot option in the 3.3 kV family, not a generic promise of performance.

The supplied construction uses three screened phase cores and one screened pilot core laid up in contact with the bare copper earth conductor, with EPR insulation and a heavy-duty chloroprene sheath. That arrangement matters because The screened pilot is the defining Type 307M feature; it is not interchangeable with Type 307 or Type 307S solely by voltage. The family should therefore be selected by model, core function and installation route as well as by voltage. The Ассортимент кабелей для горнодобывающей и туннельной промышленности provides the wider TEBAOFLEX product context.

• Выберите по: confirm the need for a screened pilot and match pilot continuity, termination and monitoring requirements to the machine system.
• Подтвердите перед заказом: 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 equipment-specific routing and handling questions around the 3.3 kV class, review the Mining & Tunnelling solutions page with this Type 307M data.

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 307M construction

The cross-section below is the supplied construction drawing for Type 307M. The ordering decision is driven by The screened pilot is the defining Type 307M feature; it is not interchangeable with Type 307 or Type 307S solely by voltage.

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 307M 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 307M construction separate from nearby Type numbers.

• Primary duty: excavating, crushing and coal-cutting equipment.
• Model boundary: The screened pilot is the defining Type 307M feature; it is not interchangeable with Type 307 or Type 307S solely by voltage.
• 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.

When the specification calls for a three-core pilot unit instead of a screened single pilot, compare the Type 307S cable and retain the exact model in the equipment 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 307M 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_307M_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 307M 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.
