We, Fibreglass Fabricators is an Indian origin company engaged in manufacturing Fiberglass Epoxy Pultruded sections used for electrical insulation in Electrical Transformers, Insulators, Lighting Arrestors, Drop out fuses, GOAB Switches, Heavy Motors and various other applications . We are situated at Kolkat in India and serving electrical industry since 1978.

As a new development, Fibreglass Fabricators has introduced itself in the Composite/Polymer insulator market with its new product, Fiberglass Epoxy Pultruded Composite Insulator Core Rod suitable for application in Composite/Polymer Insulators and Lighting Arrestors.

We manufacture a wide variety of FRP Epoxy Pultruded sections such as FRP Rods, FRP Tubes/Pipes, Dog Bone, Corner Angle, Hat section, Threaded Rods, Studs, FRP Strips/Flats, FRP Nuts and FRP Angles etc. We are supplying our products to major manufacturers in India and as well as other countries. It is the confidence and trust of our clients that has helped us to maintain the quality standards of our products.

Advantages:

Epoxy resins are impregnating compounds with the highest available quality of all comparable polymers for the pultrusions of FRP rod materials. Hot curing epoxy resin in combination with anhydride hardener gives an aging/hydrolysis resistant high strength matrix component. Polyester resins are not hydrolysis resistant and have lower mechanical and electrical properties.

Epoxy fiberglass filament wound tube is composed of continuous filaments with controlled orientation in a matrix of cured epoxy resin.  It is produced with varying angles of fiberglass filaments winding.  The angles of winding can be varied to suit different applications and strength requirements.  Typically, fiberglass filaments are wound in two directions across each other and at an angle of 50-55 degree to the longitudinal axis of the tube.

 

Epoxy fiberglass filament wound tube has good electrical insulation properties and excellent moisture resistance.  It offers excellent resistance to weather and ultraviolet rays.  Epoxy fiberglass filament wound tube is light and strong.  Its applications include high voltage insulators, fuse tubes, antennas, battery casings, bushings of high voltage equipment, railroad bushings, bearings, collars, tool handles, pressure tubing, structural tubing, reverse osmosis shell, and high pressure bottles.

Applications :

 

• Tubes for Lightening Arresters.
• OLTC Tanks & Hollow Shafts.
• Selector Column, Switch pillars, Centering Tubes for Tap-Changers.
• Fuse bodies for low & medium voltages.
• End Rings/Edge Blocks for transformers 11 KV to 400 KV applications.
• Coil formers 11 KV to 220 KV applications.
• Insulating Tubes for transformers.
• Rupturing Chambers, Arc pots for switchgears.
• Insulating rods & Operating rods (hollow) for low voltage, medium voltage & high voltage for vacuum circuit breakers, SF6 circuit switchgears.

Product Range :

 

• Tubes from ID 12mm to 3000 mm
• Wall thickness from 0.8 mm
• Length of tube up to 3m

Advantages :

 

• Filament winding is a versatile technique for composites fabrication suited for axially symmetrical components such as cylindrical pressure vessels, pipelines, cylinders for storage of high pressure gases, rocket motor casings, large underground storage tanks and electrical applications.
• Apart from strength to weight advantages and low cost of manufacturing, filament wound composite parts have better corrosion and electrical resistance.
