Polyester-polyamide tape insulated magnet wire and method of making the same

摘要

Magnet wire insulated with dielectric tape material of polyester overwrapped with aromatic polyamide is described. The tape can be spirally wrapped at high speeds onto the magnet wire substrate. The initial layer of polyester provides secure bonding of the subsequently wrapped polyamide layer. The wire is particularly useful in environments where abrasion resistant, high temperature stable magnet wire is needed which is capable of submersive use in oil and maintains its integrity when exposed to other corrosive environments.
