RES-I-GLAS Type R is superior in tensile strength, durability, insulation value, ease of application and storage shelf life, due to the uncompromised use of highest grade raw materials and consistent manufacturing process. Constructed of high tensile electrical grade glass yarns laid parallel and bonded with fully catalyzed thermosetting resins. High tensile, high modulus, low elongation, high impact strength band. Eliminates insulation and creepage problems experienced with steel wire banding. Tape is supplied semi-cured (B-Stage) in a soft well balanced flat ribbon form and this assures that each yarn bears an equal share of the load. - Type R B-Stage resin isolates the individual glass yarns, thereby preventing cutting and shearing of these yarns. Tape is stiff, hard and springy. Have successfully replaced steel wire on all types of armatures including traction, large generator, motor generator, power shovel, steel mill and diesel locomotive traction motors and generators. Very popular with winders because of its ease of application and because it eliminates the hazards present in the breaking and lashing of stressed steel.
