| Varglas VPI Acrylic Sleeving |
Description
Varglas VPI Acrylic Sleeving is a Grade A, acrylic coated Fiberglas® sleeving that has been overbraided with a secondary Fiberglas® braid which, in addition to providing increased physical protection, affords motor manufacturers, as well as rewinders, employing vacuum pressure impregnation (VPI) with both interior and exterior surfaces that are highly suitable for the absorption and retention of the low-viscosity, solvent-type and solventless resins utilized during the impregnation and drain cycles.
Because of its acrylic lineage, Varglas VPI Acrylic Sleeving is resistant to most acids, organic solvents, oils and water and exhibits fair resistance to alkalies. It is compatible with modified polyester, acrylic, epoxy, phenolic and formvar wire enamels and is designed to perform for long periods in a 155°C range without loss of any electrical or physical properties. And, since it is Grade A, it provides a minimum average short-time dielectric strength of 7000 volts before vacuum impregnation.
Specifications
The mainstay in
this composite is our standard Grade A Varglas A397 Acrylic Sleeving which
conforms to MIL-I-3190/3, latest revision; NEMA TF-1, Type 6; and
ASTM-D372.
Under the Component Program of Underwriters
Laboratories, this acrylic coated sleeving is recognized for 155°C, 600
volt service under UL File #E63450. The Canadian Standards Association
certifies its use for 155°C, 600 volt service under CSA File
#LR-58486"HFS". It also is recognized in systems work, per UL Safety
Standard 1446, to facilitate product acceptance by UL.
Applications
Varglas VPI
Acrylic Sleeving is used primarily to insulate the coil and phase leads in
random- wound and formed-coil motors which are to be resin-impregnated,
after assembly, utilizing vacuum pressure impregnation (VPI) processes.
However, because of the increased physical protection provided by the
Fiberglas® overbraid, Varglas VPI Acrylic Sleeving can also be used
whenever additional abrasion resistance and insulation system
compatibility are required in applications subjected to continuous
operating temperatures of 155°C.
