What does the designation 'Type 3013' mean in British Coal MGM 109?
In the 4-digit MGM 109 code '3013': '3' = 1.9/3.3 kV rated voltage; '0' = unscreened phase cores; '1' = Single Wire Armour (SWA); and '3' = 3 power cores. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging, and
How does MGM 109 Type 3013 compare with standard industrial BS 6622 / BS 5467 3.3 kV SWA cable?
Standard industrial 3.3 kV SWA cable uses plain copper conductors, rigid XLPE insulation, and steel wire armour with only ~20–35 % earth conductance. MGM 109 Type 3013 uses tinned copper conductors, flexible 90 °C GP4 EPR insulation, and composite steel/copper SWA achieving ≥ 75 % earth conductance.
Why does Type 3013 require more copper wires in the armour than Type 3023?
Because Type 3013 has only one layer of armour wires (SWA) rather than two (DWA), a higher proportion of tinned copper wires must be mixed into the single galvanized steel wire layer on sizes ≥ 35 mm² to meet the mandatory ≥ 75 % earth conductance rule.
Where is Type 3013 typically installed in a mine?
Type 3013 is used for 3.3 kV horizontal pit-bottom galleries, fixed pump and booster-fan motor connections, and surface coal-handling washery plants where vertical shaft suspension is not required. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging, and high-voltage AC
