Type 633 mining cable for 19/33 kV reeling and section feeders
Type 633 mining cable is a medium-voltage screened cable family rated 19/33 kV for electrically driven machines, movable and portable electric apparatus, section feeders and the open-cast mining equipment listed in the supplied SANS datasheet. It is a practical starting point for procurement teams comparing dragline, shovel, drill and other large mobile-equipment connections where a higher-voltage cable schedule and cable-management method must be reviewed together.
The standard Type 633 arrangement uses three individually screened flexible power cores laid up with three insulated pilot cores. Each power core uses Class 5 tinned annealed copper and triple-extruded EPR with a strippable semi-conducting screen. The source also defines a 633-ECC option: one pilot core is replaced with a tinned conductor. Nylon/tinned-copper braid, CR polychloroprene sheathing and open nylon reinforcement complete the listed construction.
Select Type 633 or 633-ECC according to the equipment earthing and monitoring design, then match conductor area, reeling route, termination, cable length and handling equipment. Specifications preserves the separate dimensional, ECC, electrical and service tables from the PDF. For adjacent voltage and construction comparisons, visit the Антикапиллярный провод | GXL и TXL | SAE J1128 category and use the related products below; the RFQ should state whether the ECC conductor is required.
Type 633 and 633-ECC screened MV construction
Type 633 uses individually screened medium-voltage power cores laid up with three insulated pilot cores. The ECC designation changes the monitoring/earth arrangement by replacing one pilot core with a tinned conductor; that choice should remain visible in the equipment and termination schedule.

| Дирижер | Гибкая многожильная луженая отожженная медь 5-го класса |
| Изоляция | EPR thermosetting compound with strippable semi-conducting core screen, triple extruded |
| Power-core screen | Each power core individually screened with tinned copper / textile braid |
| Пилотные ядра | Three pilot cores insulated with EPM in the standard Type 633 construction |
| ECC option | One pilot core replaced with a tinned conductor |
| Усиление | Open nylon braid, minimum 16 strings |

The cross-section distinguishes the power, pilot and ECC paths visually; use the original PDF tables and cable schedule to approve the selected core area, screen data, dimensions and mass.
Type 633 for high-voltage mobile mining connections
Type 633 is the higher-voltage option in this two-product set. Its source application combines portable and movable equipment with section-feeder duty, and names open-cast machines where reeling and cable handling are part of the installation brief.
- Medium-sized draglines, shovels and drills in open-cast mining as listed by the source
- Portable electric apparatus and section feeders requiring the 19/33 kV rating
- Reeling purposes and other industrial applications covered by the supplied datasheet
- Equipment interfaces where the standard three-pilot design or 633-ECC tinned-conductor option must be selected explicitly
- Before ordering, confirm reel/guide layout, termination geometry, cable length, earth-fault scheme and the machine supply voltage
The PDF lists a 9 × overall-diameter minimum bending radius and tabled maximum tension values, but it does not state a reeling speed or dynamic service life. Treat those as project engineering inputs rather than generic Type 633 claims.
Type 633 / 633-ECC 19/33 kV Mining Cable technical data
The dimensional, electrical and service values below are transcribed from the supplied PDF for Type 633 mining cable. Tables remain separated by the construction or service section used in the source, so the applicable row can be matched to the equipment schedule without inventing a merged product range.
Use the source-listed conductor area, core dimensions, overall diameter, mass and electrical values together. Where the PDF gives a bending, tension, current or short-circuit value, it remains in the table; where it does not, no universal project rating is added.
