How do MGM 118 Type 6010 and Type 6020 decode?
Under British Coal Specification MGM 118 for 3.8/6.6 kV ('6') 3-core cables: the second digit '0' indicates unscreened phase cores; the third digit indicates armour ('1' = Single Wire Armour in Type 6010, '2' = Double Wire Armour in Type 6020); and the fourth digit '0' is the MGM 118 3-core 6.6 kV series identifier.
What is the difference between British Coal MGM 109 and MGM 118?
MGM 109 covers 640/1100 V (10xx series) and 1.9/3.3 kV (3xxx series) armoured mining roadway cables, whereas MGM 118 covers 3.8/6.6 kV (6xxx series) medium-voltage armoured mining trunk cables. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging, and high-voltage
When is unscreened Type 6010/6020 specified instead of individually copper-screened Type 6110?
Type 6010 and Type 6020 are specified where existing underground 6.6 kV bolted cable couplers and transwitch terminal chambers are designed for unscreened coordinated-wall EPR cores with collective metallic armour earthing. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging,
How does Type 6010/6020 achieve ≥ 75 % earth conductance at 6.6 kV?
High-conductivity tinned copper wires are stranded alongside the galvanized steel armour wires in calculated proportions so the metallic armour conductance is always ≥ 75 % of one phase conductor. Each production drum undergoes 100 % conductor DC resistance verification, insulation thickness gauging, and high-voltage
