Industrial Transformer Fabrication Gujarat Manufacturer – Kay Pee Quality
Trust Kay Pee for reliable industrial transformer fabrication Gujarat with oil-cooled transformers and dry-type builds by top local manufacturer. Our 20,000 sq ft facility uses CRGO silicon steel cores, copper/aluminum windings, and advanced winding machines for superior quality and durability.
From core assembly to tank fabrication, every step follows strict quality checks. We produce oil-immersed distribution transformers for outdoor use, cast resin dry-type transformers for indoors, and hermetically sealed units for low maintenance. Kay Pee’s custom transformer manufacturing Gujarat serves textiles, chemicals, and power sectors with fast turnaround.
Oil-Cooled Transformer Advantages
Kay Pee’s oil-cooled transformer advantages make them ideal for heavy industry. Enjoy better cooling through mineral oil circulation, handling up to 120% overload capacity for peak demands without damage. Cost-effective for 100kVA+ ratings cheaper than dry-type while lasting 25+ years.
Oil absorbs heat efficiently, reduces hotspots, and allows natural/submerged cooling (ONAN/ONAF). Perfect for outdoor substations, factories, and Gujarat’s hot climate. As custom transformer manufacturer Gujarat, India. Kay Pee adds Protection against low maintenance. Superior to air-cooled for high-power distribution transformers.
Dry-Type Transformer Fabrication Process
Kay Pee masters the dry-type transformer fabrication process using epoxy resin casting and vacuum pressure impregnation (VPI) for top insulation. Epoxy encases windings completely, preventing moisture and dust ingress – ideal for indoor factories, malls, and hospitals.
VPI under vacuum pulls resin deep into coils for void-free insulation, boosting dielectric strength by 30%. Our Gujarat facility uses Class-H materials (220°C rating) for fire safety (no F10 oil equivalent). Results in dry-type transformers with IP23-54 protection – transformer building services excellence.
Quality Testing at Kay Pee Gujarat Factory
Every transformer passes quality testing at Kay Pee Gujarat factory with 10+ routine tests ensuring zero defects. Key checks include ratio measurement (accuracy ±0.5%), winding resistance, oil BDV (>50kV for new oil).
Additional tests cover no-load losses, load losses, temperature rise, and partial discharge. Type tests like short-circuit withstand verify design strength. As transformer manufacturer India, we provide test certificates for BIS compliance and third-party inspection – confidence in every custom transformer manufacturing Gujarat unit.
