The SERIES 507 is the most economical fluoroplastic insulated wire. Individual conductors are coated with a layer of color coded FEP. The insulated conductors are then parallel duplexed with an additional layer of color coded FEP. The finished construction has a continuous temperature rating of 400°F (204°C). Abrasion, moisture and chemical resistance exceed most other insulations. This construction is widely used when pulling long lengths of wire through conduit. FEP’s low friction coefficient and abrasion resistance are suited for these applications.
