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.

For distribution and power transformer coil manufacturing
MTM heavy-duty expandable winding mandrels are made for coil form diameters from 6 in. (150mm) to 50 in. (1,270mm) diameter, and for coil lengths up to 135 in. (3430mm).
Manufactured with a steel structure, the MTM round winding mandrels are designed to provide an infinite adjustment of the outer diameter within the specified range of the mandrel. The expansion system is designed to support the mandrel under compressive load and will not collapse during winding. Aluminum leaves has a radius on 2 edges providing a support surface and spacing against the inside of the coil over the full diameter range.
Suitable for HV and LV coil winding applications, adaptable to any OEM machines
The mandrels are designed to bolt to the winding machine headstock or to be removed with the coil when the coil winding is complete (depending on the application).
The mandrel structure is finished in BLACK or ORANGE unless otherwise specified, and parts are nickel or zinc plated where required.
