LH Marthinusen (Johannesburg) have one the most well equipped stator coil manufacturing operations in the Southern hemisphere.  Coils of any type and size are manufactured in-house, from the drawing and covering of the copper conductor through to the stretching, forming, pressing and high voltage testing.  Both soft cell (VPI) and resin-rich coils can be manufactured.  This self-sufficiency results in delivery periods being offered in days rather than weeks.
