- Basic information
The REISSMANN Sensortechnik heater bands were
specifically designed for the electric motor industry.
These heater bands are delivered as a finished product,
in various combinations, of length and power output.
- Application
The heater bands prevent condensation in electric
motors and also protect against frost damage. If
condensation occurs inside the motor, creepage
currents and short circuits may occur.
- Advantages
• exclusive usage of silicone-free material
• prevention of „outgassing of silicone“
• protection of people and equipment, from dangerous
gases
• very flexible design facilitates the matching of product
to application
- Construction
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 heater band system is sewn into a fiberglass hose
or sleeve (Fig. 1 and 3). The sewing in of the lead-in, at
the end of the fiberglass hose, gives additional strain
relief at the junction between the Teflon insulated
resistance winding and the lead-in.
- Certification
VDE: 40029602
UL: E325880
