Type 630 / Type 631 BS 6708 3800/6600 V Armoured Mining Cable

Type 630 / Type 631 for excavating and crushing machines and equipment

Type 630 / Type 631 mining cable is specified in the supplied BS 6708 datasheet for excavating and crushing machines and 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 high-voltage armoured screen-and-earth decision, not a generic promise of performance.

The supplied construction uses three individually screened phase cores with galvanized steel pliable armour; Type 631 adds one unscreened earth core while Type 630 is the three-phase screened construction. That arrangement matters because Type 630 and Type 631 are both armoured 3800/6600 V choices; the earth-core distinction is the essential ordering boundary. 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 phase voltage, earth-core requirement, screen termination, armour interface and the machine protection arrangement.
• 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 high-voltage armoured replacement review, the BS 6708 mining cable replacement guide helps separate voltage, armour and screening choices across the BS 6708 families.

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 630 / Type 631 construction

The cross-section below is the supplied construction drawing for Type 630 / Type 631. The ordering decision is driven by Type 630 and Type 631 are both armoured 3800/6600 V choices; the earth-core distinction is the essential ordering boundary.

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 630 / Type 631 applications

The supplied datasheet identifies this cable for excavating and crushing machines and 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 630 / Type 631 construction separate from nearby Type numbers.

• Primary duty: excavating and crushing machines and equipment.
• Model boundary: Type 630 and Type 631 are both armoured 3800/6600 V choices; the earth-core distinction is the essential ordering boundary.
• 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.

A screened trailing layout at the same higher voltage can be compared through the Type 730 mining cable; confirm armour, screening and termination requirements for the actual route.

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 630 / Type 631 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_630_TYPE_631_3_8_6_6KV_ARMOURED_CABLE_datasheet.pdf; 3 pages; 5 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 630 / Type 631 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.
