FAQ

Questions engineers ask first

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

What is the difference between MGM 109 Type 1012, Type 1013, and Type 1014?
All three are 640/1100 V ('1'), unscreened ('0'), single-wire-armoured ('1') EPR/PVC mining cables to British Coal MGM 109. The final digit specifies the number of insulated cores: Type 1012 has 2 cores (single-phase lighting/control), Type 1013 has 3 cores (3-phase power), and Type 1014 has 4 cores (3-phase + neutral/pilot).
How does Single-Armoured MGM 109 (Type 1013) maintain ≥ 75 % earth conductance on large cross-sections?
With only a single layer of armour wires, galvanized steel alone cannot match 75 % of the conductance of 70 mm² to 185 mm² copper phase conductors. We intersperse high-conductivity tinned copper wires within the galvanized steel SWA layer so the combined armour conductance exceeds 75 %.
When is Single Wire Armour (Type 1012/1013/1014) selected over Double Wire Armour (Type 1023/1024)?
Single Wire Armour is specified for permanent horizontal galleries, pit-bottom substation rooms, lighting distribution, and surface colliery plants where tighter 8×D routing and lower weight are preferred over the vertical shaft suspension strength of DWA. Each production drum undergoes 100 % conductor DC resistance
Can MGM 109 Type 1013 be terminated with standard industrial BS 6121 SWA glands?
In non-hazardous surface washery buildings, heavy-duty industrial SWA glands can be used; in underground gassy coal roadways (Group I), BS 6708 / ATEX Group I Ex d mining glands and bolted coupler boxes must be used. Each production drum undergoes 100 % conductor DC
