Polygon Co. (Walkerton, Ind., U.S.), producer of composite tubing, bearing and pneumatic cylinders, has introduced double insulation dielectric composite tubing for electric motor applications. The Polygon Tube brand of double insulation tubing is said to be customizable to an individual application’s needs to ensure high quality and safety for each motor.

Used as a sleeve within the armatures of electric motors, Polygon Tube double insulation tubing acts as a secondary layer of insulation and provides shock protection to the operators of electrical tools and appliances. The additional layer of insulation allows the appliance to be rated “Double Insulated,” which the company says eliminates the need for grounding of the unit.

Polygon’s design and performance engineers are available to assist customers in determining the best fiber architecture and finishing to produce secondary insulating sleeves that fit users’ needs. Options include custom sizes, and machining holes and cutouts to fit various applications.

According to Polygon, the use of composite materials enables the tubing to be tailored to meet many engineering challenges. The materials’ dielectric and insulating properties are said to eliminate risk of capacitance coupling, and their high torque strength is said to ensure durability. For increased design flexibility, Polygon also offers capabilities in fiber winding and finishing.

Polygon Tube double insulation tubing holds an Underwriter’s Laboratories (UL) certification AFW-G-10, and the company says that every finished tube is tested at 5,000 volts minimum to guarantee its dielectric integrity.
