RUBY MICA COMPANY LIMITED

Giridih, Jharkhand

Our company is a prominent Manufacturer, Exporter and Supplier of Glass Mica Cable Tape from India. Glass Mica Cable Tape is a lamination of uncalcined phlogopite/muscovite mica paper with a glass cloth. Our experts use a high thermal-grade silicon resin as a binder, making it a class ‘H’ insulation product. Glass Mica Cable Tape is suitable for power and control cables, instrumentation and signaling cables owing to its fire resistant properties. Also, our Glass Mica Cable Tape is high-speed taping machine-compatible dues to its supreme flexibility and tensile strength.  We provide Glass Mica Cable Tape in different technical specifications at market leading prices.

At The Forefront of Innovation :Ruby Mica Co. Has developed a high performing range of mica tapes especially for fire resistance cable insulation. After years of rigorous R&D we improvised the process of laminating mica paper and glass cloth together, creating a product that is impervious to twists and turns, rendering the mica paper layer invincible from all possibilities of surface cracking or peeling during its handling and apllication. In the unfortunate event of a fire the silicone binder in the mica tape undergoes pyrolysis forming a protective ceramic layer on the wire considerably enhancing the fire-fighting capabilities of cable tapes.
We strongly believe that good ingredients make a great end-product, hence we start by manufacturing the highest grade of mica paper ourselves, specifically pick recommended backing-materials, finally laminate them together using world-renowned binding resins, which keeps product-aging in check and at the same tiem ensures a longer shelf-life. The moment you receive your consignment, you will discover our expertise and finese shining through our products. A highly reliable product and honest princing policy comes as a standard when you deal with us.

Glass Mica Cable (GMCAB) Tape  : Ruby Mica GMCAB tape is a lamination of uncalcined phlogopite / muscovite mica paper with a glass cloth. A high thermal-grade silicone resin is used as a binder, making it a class 'H' insulation product.


Glass Mica Cable Tape Reinforced With Polyester Film (GMPCAB) Tape :Ruby Mica GMPCAB Tape is a lamination of uncalcined phlogopite/muscovite mica paper with PET film one side and glass cloth on the other, making it a three-layer high-performance mica tape. What makes this tape truly special is its unique blend of high tensile strength imparted by glass cloth, strong electrical resistance borrowed from the pet film and superior thermal-sustenance brought about by the use of the best quality mica there is. A high thermal-grade silicone resin is used as a binder, making it a class 'H' insulation product.
An additonal layer of PET film secures the mica paper in its position at all times, while providing a seamless mica tape lapping on the wires. The addition of pet film to the glass mica tape reduces the hassle and one time-consuming activity for the cable companies who wrap a single layer of pet film on their cables after wrapping the glass mica tape as well. Pet film adds on 3.5kv of break down voltage protection to electric cables operating below 120oC. We ran a lot of suitability tests in our labs in order to study the behavior of Pet film at different temperature increments and found out that it simply vanishes without a single trace at 600 oC. Thus you can rest assured that the pet film enhances the mica tape's workability multi-fold without altering its fire-fighting properties in any way.

Application :Glass Mica Cable Tapes impart fire-resistant properties to the electric cables and are suitable for power and control cables, instrumentation and signaling cables. Circuit-integrity is ensured by these tough and resilient FRLS cable tapes during fire and in high-temperature environments up to 950 oC. Due to their superior flexibility and tensile strength, all our GMCAB / GMPCAB tapes are high-speed taping machine-compatible. The product is compliant to IEC 60371-3-8.

Packing : Tapes are packed in airtight mechanically strong boxes protecting them from dirt, dust and mositure. The packaging also ensures safe transit and storage.

Storage : 12 months at 20 oC

We are instrumental in manufacturing, exporting and supplying Glass Mica Polyester Tape. Our Glass Mica Polyester Tape is known for its unique blend of high tensile strength imparted by glass cloth, strong electrical resistance and superior thermal endurance.

We provide Glass Mica Polyester Tape in two different insulation classes. Further, Glass Mica Polyester Tape finds wide application in overhung insulation of the coils and bars in HT motors and generators.

Ruby Mica Glass / Mica / pet Film Tape is a lamination of uncalcined muscovite mica paper with pet film one side and glass cloth on the other, making it a three layer high-performing mica tape. What makes this tape truly special is its unique blend of high tensile-strength imparted by glass cloth, strong electrical-resistance borrowed from the Pet film, and superior thermal-endurance brought about by the use of best-quality mica there is.

These tapes can withstand the rigorous overhang taping operation through sharp bends and curves without loosing their insulation value. They can be supplied in two different insulation classes. Class H insulation uses only the high thermal-grade silicone resin or modified polyester resin as a binder, whereas class f insulation uses an epoxy resin as a binder.

Less space constraints give way to a thicker insulation for the coil overhangs. An Additional fourth layer of pet film may also be laminated on the glass cloth side. This PGMP Tape has an increased dielectric value, better tensile-strength and provides a seamless mica tape-lapping on the coils.
