This British Standard specifies requirements and dimensions for flexible cables used in mining and quarrying.<\/p>\n

Specific types of cable covered in this standard are as follows:<\/p>\n

    \n
  1. \n

    non-armoured cables having individually metallic screened cores and a rated voltage of 640\/1100 V, for use:<\/p>\n

      \n
    1. \n

      with coalface cutters and other similar machines: types 7, 7M, 7S, 11, 14 and 16;<\/p>\n<\/li>\n

    2. \n

      in overhead catenary systems and similar applications: types FS4 (flat form cable);<\/p>\n<\/li>\n<\/ol>\n<\/li>\n

    3. \n

      cables with galvanized steel pliable wire armouring, with:<\/p>\n

        \n
      1. \n

        unscreened cores and a rated voltage 640\/1100 V: types 20 and 21; or<\/p>\n<\/li>\n

      2. \n

        individually metallic screened or unscreened cores and a rated voltage 640\/1100 V used primarily for remote control circuits and coalface lighting: types 62, 63, 64, 70 and 71; or<\/p>\n<\/li>\n

      3. \n

        individually metallic screened cores and a rated voltage 640\/1100 V: types 201 and 211; or<\/p>\n<\/li>\n

      4. \n

        a rated voltage 1900\/3300 V used as trailing cables in quarries or for mine roadway cable extension purpose: types 321 and 331;<\/p>\n<\/li>\n<\/ol>\n<\/li>\n

      5. \n

        auxiliary cables with galvanized steel pliable wire armouring having up to 24 individually metallic screened cores and a rated voltage 320\/550 V, primarily for use on large mining machines where interconnection between machine sections or a machine section and auxiliary equipment is required: types 506, 512, 518 and 524;<\/p>\n<\/li>\n

      6. \n

        cables with galvanized steel pliable wire armouring having individually metallic screened or unscreened cores and a rated voltage 3800\/6600 V, used as trailing cables in quarries and rated for roadway extension purposes: types 621, 630 and 631;<\/p>\n<\/li>\n

      7. \n

        non-armoured cable having individually metallic screened cores and a rated voltage 600\/1000 V, primarily for use with hand-held drilling machines in mines: type 44;<\/p>\n<\/li>\n

      8. \n

        non-armoured cable having individually non-metallic screened cores and a rated voltage 600\/1000 V, primarily for use with hand-held drilling machines in mines: type 43;<\/p>\n<\/li>\n

      9. \n

        non-armoured cable having individually metallic screened cores and a rated voltage 3800\/6600 V, primarily for use as trailing cables for large machines at quarries: type 730;<\/p>\n<\/li>\n

      10. \n

        non-armoured cable having individually metallic screened cores and a rated voltage 6350\/11000 V, primarily for use as trailing cables for large machines at quarries: type 830;<\/p>\n<\/li>\n

      11. \n

        non-armoured cables having individually metallic screened cores and rated voltage 1900\/3300 V, for use with coalface cutters and other similar machines: types 307, 307M and 307S.<\/p>\n<\/li>\n<\/ol>\n
