[Motor and machine protection]

The heaterbands prevent condensation in electric motors and also protect against frost damage. If condensation occurs inside the motor, creepage currents and short circuits may occur.

The carrier material consists of a glass yarn and a resistance wire that is wound round the glass yarn. Afterwards the glass yarn is insulated by Teflon (Fig.2). The junction between the lead-in and the resistance wire are insulated on both sides with shrink tubes. For protection against damage, from external sources, the entire heaterband system is sewn into a fibreglass hose or sleeve (Fig. 1). The sewing in of the lead-in, at the end of the fibreglass hose, gives additional strain relief at the junction between the teflon insulated resistance winding and the lead-in.
