Polygon Tube® double insulation tubing is used as a sleeve within the armatures of electric motors. This secondary layer of insulation protects electrical tool operators from shock and eliminates the need for grounding the unit. Our design and performance engineers use their extensive knowledge and experience in composites science to assist you in determining the best fiber architecture, resin formulations and finishing to produce your ideal application. This can include sizes, colors, along with machining holes and cutouts to fit numerous applications.
Materials and finishes can be customized to your needs, meaning you’ll get exactly what you need
Outstanding dielectric & insulating properties eliminate the risk of capacitive coupling
High Torque Strength means less wear and tear, and less cost for replacements
UL approval to grade AFW-G-10.
Quality control. Every finished tube is tested at 5000 volts minimum to guarantee its dielectric integrity.
MANUFACTURED FOR OPTIMAL PERFORMANCE
Polygon Tube provides high torque strengths and has a UL Certified continuous temperature index rating of 120°C. This patented manufacturing technique produced double insulated tubes with unparalleled physical properties and unmatched electrical insulation.
Standard Tolerances
In comparison to conventional molding or paper tube assemblies, the implementation of the Polygon Tube into the motor assembly enables the manufacturer to reduce production costs. Standard tolerances have been established that allow these composite tubes to be slipped or press-fit into the motor laminations. The armature shaft is then pressed into the assembly, securely locking the laminations and the shaft.
