A floor standing modular unit for producing the helical and annular corrugations in the welded conductor of a power cable in tandem with the longitudinal welding design and operation. The combination of the rugged steel frame dynamically balanced corrugating head assembly ensures smooth vibration free operation.A Hollowshaft spidle design is driven by a permament magnet (servo) motor or an AC inverter duty motor and can bust the corrugating speed up to 2000 RPM.
