FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

How do MGM 112 Type 62, Type 63 and Type 64 differ from one another?
Aligned with BS 6708 Type 62, 63 and 64, all three are 660/1,100 V pliable-wire-armoured underground mining auxiliary cables in 4, 6 and 10 mm² conductor sizes: Type 62 has 2 individually copper/nylon-screened cores; Type 63 has 3 individually copper/nylon-screened cores; and Type 64 has 3 individually copper/nylon-screened live cores plus 1 unscreened earth core laid around a central rubber cradle.
Where are Type 62, Type 63 and Type 64 typically installed in underground mines?
They are used for 110 V to 1,100 V flameproof underground roadway lighting strings, conveyor pull-wire signalling, methane/ventilation interlocking circuits and small auxiliary drives where individual core screening and pliable steel wire armour are required.
How do Type 63 / Type 64 relate to MGM 112 Type 201 / Type 211?
Type 63 (3 screened cores) and Type 64 (3 screened + 1 earth) are the small-cross-section auxiliary series (4–10 mm²), whereas Type 201 and Type 211 extend the same individually screened pliable-wire-armoured architecture across power cross-sections up to 150 mm².
What if individual core screens are not required on my 2-, 4- or 5-core auxiliary circuits?
For unscreened armoured 660/1,100 V mining cables in 2-core, 4-core or 5-core configurations, select our MGM 112 Type E2 / E4 / E5 Unscreened Armoured Auxiliary Cable.
