What is a Transformer Insulation Kit?

A transformer insulation kit is a complete, matched set of all insulation components required to build or rewind a transformer. Rather than sourcing pressboard, densified wood, epoxy components, and other insulation materials from multiple suppliers — a kit supplies everything in one order, cut and fabricated to your transformer's exact design dimensions.

For transformer manufacturers, rewinders, and service engineers, a complete insulation kit eliminates procurement complexity, reduces lead time, and ensures every component is dimensionally compatible before assembly begins. ARiC Insulation has been supplying transformer insulation components and complete kits to India's transformer industry since 1969.

What is Included in an ARiC Transformer Insulation Kit?

Each kit is assembled to match your transformer design specification. Components are manufactured in-house and supplied as a complete matched set. A standard kit includes:

Pressboard components — coil supports, end rings, corner angles, clackbands, and phase barriers manufactured from high-density pressboard to IS 1576 standard. Available in calendered and pre-compressed grades.
Densified wood (Permali / Permawood) components — coil formers, distance pieces, and support blocks manufactured from compressed densified wood for high mechanical strength applications.
Epoxy glass laminate components — epoxy sheets, epoxy tubes, and machined components in G10/G11 equivalent grades to IEC 60893 for high dielectric strength requirements.
FRP components — fibre reinforced plastic sheets, pultruded profiles, and machined parts used for structural insulation within the transformer assembly.
Diamond dotted paper — used between winding layers as a bonding insulation that activates under heat during the drying process.
Pre-compressed pressboard — dimensionally stable under compression, used for critical mechanical support applications where conventional pressboard would compress over time.
Custom components — any additional insulation parts specific to your transformer design, manufactured to drawing.

Transformer Types Covered

ARiC Insulation supplies transformer insulation kits for both major transformer types used in India's power distribution and industrial sectors:

Transformer Type	Details
Oil-cooled (ONAN/ONAF)	Kits include oil-compatible insulation materials — pressboard, kraft paper, diamond dotted paper, and densified wood — all rated for continuous immersion in transformer oil. Suitable for distribution and power transformers up to 66KVA.
Dry-type (Cast Resin / Air Cooled)	Kits include epoxy glass laminates, FRP components, and high-temperature rated insulation materials suitable for dry-type transformers used in indoor substations, commercial buildings, and industrial facilities.
Rating range	Currently supplying kits for transformers up to 66KVA. Higher ratings available on request — contact us to discuss your specification.
Custom ratings	Expanding capability for higher KVA ratings. Contact our team to discuss requirements beyond 66KVA — we will advise on feasibility and lead time.

Why Order a Complete Insulation Kit?

Single source, single order — every component sourced from one manufacturer means one purchase order, one delivery, and one point of contact for quality issues. No chasing multiple suppliers.
Dimensionally matched components — all parts in the kit are manufactured to your transformer drawing simultaneously, ensuring perfect fit and compatibility before assembly begins.
Reduced procurement time — ordering individual components from multiple suppliers adds weeks to your procurement cycle. A complete kit from ARiC typically ships within 10–15 working days of drawing approval.
Consistent material quality — all components manufactured in-house at our Maharashtra facility under the same quality controls, eliminating variation between suppliers.
Ideal for rewinding and refurbishment — transformer service engineers and rewinders can order a replacement insulation kit matched to the original design, making refurbishment faster and more reliable.

Why Choose ARiC Insulation for Transformer Insulation Kits?

50+ years supplying India's transformer industry — established in 1969, we have been supplying transformer insulation components and kits to manufacturers, rewinders, and OEMs across India for over five decades.
Complete in-house manufacturing — pressboard cutting, densified wood machining, epoxy laminate fabrication, FRP processing — all done at our Maharashtra facility. No outsourcing.
CNC machining for precision components — critical dimensions are CNC machined to tight tolerances, ensuring components fit without on-site modification.
Material expertise across all insulation types — our team can advise on the correct material grade for each component in your design, optimising for performance, cost, and availability.
Kits for both new build and refurbishment — whether you are manufacturing a new transformer or rewinding a failed unit, we can supply a complete matched insulation kit to your specification.

Frequently Asked Questions

What transformer ratings do you supply insulation kits for?

We currently supply complete transformer insulation kits for transformers up to 66KVA — covering both oil-cooled and dry-type designs. We are actively expanding our capability for higher ratings. Contact us to discuss requirements beyond 66KVA.

Can you supply a kit for a non-standard or custom transformer design?

Yes. Share your transformer drawing or component list and our team will review it and provide a complete kit quotation. All components are manufactured to your specific dimensions — we do not supply standard off-the-shelf kits.

What is the difference between an oil-type and dry-type insulation kit?

Oil-type kits use pressboard, kraft paper, and densified wood — materials compatible with transformer oil immersion. Dry-type kits use epoxy glass laminates and FRP components rated for air-cooled, non-oil environments. We supply both — specify your transformer type when requesting a quote.

Can I order individual components instead of a complete kit?

Yes. All components available in the kit — pressboard, densified wood, epoxy laminates, FRP components, diamond dotted paper — are also available as individual items. Browse our transformer components range for individual product pages.

What is your lead time for a transformer insulation kit?

Typically 10–15 working days from drawing approval, depending on the number of components and complexity of machining required. Contact us for a specific timeline based on your design.

Do you supply transformer insulation kits outside Maharashtra?

Yes. We supply to transformer manufacturers and rewinders across India. We are also expanding to international markets including the Middle East, UK, and Southeast Asia.
