For distribution transformer coil manufacturing

MTM manufactured 2-way and 4-way expandable mandrels for integration with MTM and other OEM winding machines. Mandrels are designed to accept a variety of forms allowing rectangular, square, and obround coil constructions.

Manufactured with a steel structure, the MTM rectangular winding mandrels are designed to provide an infinite adjustment of the outer diameter within the specified range of the mandrel (expanding range typically 1.50 in). The expansion system is designed to support the mandrel under compressive load and will not collapse during winding. Aluminum leaves are designed to accept forms and can be designed to provide a mounting location for the starting busbar.

Suitable for HV and LV coil winding applications, adaptable to any OEM machines

The mandrels are designed to bolt to the winding machine headstock, however, MTM can design custom mounting solutions to meet specific applications. The mandrel structure is finished in BLACK or ORANGE unless otherwise specified and parts are nickel or zinc plated where required.
