TT5 WinderThe ‘TT5 Winder’ was designed and manufactured by ETSM Technical Services Ltd. for use in the electrical distribution transformer industry. The T5HD winder has a 5 HP electric motor to drive the winding process. This motor drives a multi speed gearbox. The T5HD is equipped with a spring operated disk brake that is released pneumatically. Winding is controlled using a foot pedal that accelerates the winder up to the maximum speed to which the winder is set. There is also an option for the T5HD winder to control a de-reelers functions (by others), via the control panel.
