WOVEN TAPE
Description
These tapes are produced by weaving on narrow fabric looms in various thickness & weave density. The tapes are available generally in plain weave & twill weave upon request. The tapes are rolled on to a core to a required length. Core size and tape length are as per customer requirement. The tapes are in loom state condition with uniform selvedge.

Application
Our woven tapes find application in electrical industry for insulation purposes, in stator & rotor coils in rotating machines, transformers power cables, epoxy cast coils, dry type transformers and general FRP applications

Common Features
  • Excellent di-electric properties.
  • Good chemical resistance.
  • Good reinforcement to insulating varnishes
  • Armoring against mechanical damage.
  • The Glass Fibre Tapes serve as high temperature reinforcement to electrical insulating varnishes on the coil of the motors. Glass Tape are suitable upto class C, have dimensional stability and are incombustible.
  • The Polyester Fibre Tapes finds application in electrical rotating machine industry for armoring of mica based insulation, finishing and tying of coils. These Woven Polyester Tapes are suitable upto class F and is heat shrinkable supporting added tightness to the windings.
  • The Glass + Polyester Fibre Tapes are usually used for similar application as glass tape but has advantage of non fraying edges due to polyester yarn being in the weft direction and glass in the warp direction. These Woven Glass + Polyester Tapes are hybrid tapes with high tensile & incombustible properties of glass fibre in the machine direction and ease of handling of polyester fibre across. Or vice versa where polyester is in machine direction as warp to support shrinkage & glass across in weft for use temperature enhanceme
  • The Cotton Fibre Tape being Heat Class A material can with stand 105°C finds it application in oil filled transformer , rotating electrical machines for the purpose of core wrapping ,press board cylinders bandaging reinforcement for insulating varnishes and and other general industrial purposes.
Selection of Woven Tape
  • The choice of our woven tape to be used for a particular job usually depends on the following
  • Temperature class : Class A-105 C, o o Class B 130 C, Class H-180 C, Class C o above 180 C
  • Thickness : The allowable thickness of the tape in relation to the end use can be an important criterion. The nominal thickness measured between the selvedges, for woven tapes are usually from 0.09 mm. to 0.23 mm. Higher thickness are available upon request.
  • Width of the tape : Depending on the end use, various widths from 10 mm to 100 mm can be used. The tolerance on width is + 1.0 mm for nominal widths upto and including 25 mm and + 1.5 mm for nominal widths over 25 mm oupto 10% based on the requirement.
  • Weave Density : No of ends in warp & weft direction per unit length signify weave density. Various options are available.
  • Length of the tape : Standard 50 meters. However available as per customer requirement in other lengths also.
  • Breaking Strength : This is an important criteria, since while winding, the tape should not tear off or disloca
Technical Data
Typical values shown for 25 mm unit width of standard thickness. For other widths proportionate values are applicable.Tape are available in width ranging from 10 mm to 110 mm. Item code along with width in mm is required to convey the requirement of the desired tape. For tapes not covered by this table, the customer may.
