ABI Engineering Services brings in handling OLTC units across all major makes and models, delivering precision servicing, installation, and refurbishment for industries that demand consistent performance and zero downtime. We ensure your transformer operates safely, efficiently, and smoothly, even under fluctuating load conditions. Our OLTC Service Capabilities 1. OLTC Sales (All Capacities) We supply high-quality OLTC units suitable for various transformer ratings: New OLTCs from trusted OEMs Replacements for aged or failed units Compatible with distribution & power transformers Long mechanical life with high switching reliability Every OLTC is tested before delivery for assured performance. 2. OLTC Servicing & Overhauling End-to-end maintenance for smooth tap-changing operations: Diverter switch cleaning Contact replacement Selector mechanism inspection Lubrication & alignment Motor drive servicing Seal & gasket replacement We restore old OLTC units to near-new condition. 3. OLTC Fitting & Integration Precise installation for trouble-free functioning: Mounting & coupling Electrical interconnections Drive mechanism alignment Tap sequencing checks Functional and timing tests Our technicians ensure perfect synchronization with the transformer. 4. OLTC Oil Filtration (Diverter Oil) Oil purity is critical for OLTC life. We perform: Moisture removal Gas removal BDV improvement Filtration & dehydration Diverter compartment cleaning Healthy oil prevents arcing, carbon buildup, and contact wear. 5. OLTC Spares Supply We provide genuine spares for all leading OLTC types: Diverter & selector contacts Motor drive units Gear mechanisms Gaskets & O-rings Contact kits Seals & insulation components RTCC components All spares meet OEM-grade quality. 6. OLTC Refurbishment Complete rebuild solutions for malfunctioning or old units: Mechanical overhauling Drive mechanism recalibration Full cleaning & reconditioning Replacement of worn parts Housing repairs Refurbishment extends OLTC life significantly. 7. RTCC Panel Integration We supply and integrate Remote Tap Changer Control Panels: Auto/Manual modes Voltage monitoring Remote tap command Smooth tap sequencing Industrial protection features Ensures total OLTC automation and stable regulation. 8. OLTC Troubleshooting & AMC We provide rapid response for issues such as: Tap change failures Motor drive faults Contact wear Diverter issues Overheating Noise/vibration problems Annual Maintenance Contracts ensure long-term reliability and safety. https://www.abiengineeringservice.in/vacuum-circuit-breaker.htm https://www.abiengineeringservice.in/vacuum-circuit-breaker.htm Mon, 02 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/control-transformer.htm https://www.abiengineeringservice.in/control-transformer.htm Thu, 12 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/transformer-bushing-rod.htm https://www.abiengineeringservice.in/transformer-bushing-rod.htm Thu, 12 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/hinge-assembly-3-roller.htm https://www.abiengineeringservice.in/hinge-assembly-3-roller.htm Thu, 12 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/porcelain-transformer-bushing.htm https://www.abiengineeringservice.in/porcelain-transformer-bushing.htm Thu, 12 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/oltc-spares.htm https://www.abiengineeringservice.in/oltc-spares.htm Thu, 12 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/sf6-breaker.htm https://www.abiengineeringservice.in/sf6-breaker.htm Thu, 12 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/ctr-moving-electrical-contact-assembly.htm https://www.abiengineeringservice.in/ctr-moving-electrical-contact-assembly.htm Sat, 14 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/oltc-motor.htm https://www.abiengineeringservice.in/oltc-motor.htm Sat, 14 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/rtcc-panel.htm https://www.abiengineeringservice.in/rtcc-panel.htm Sat, 14 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/oltc-main-spring.htm https://www.abiengineeringservice.in/oltc-main-spring.htm Sat, 14 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/oltc-moving-contact-assembly.htm https://www.abiengineeringservice.in/oltc-moving-contact-assembly.htm Sat, 14 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/camshaft-assembly.htm https://www.abiengineeringservice.in/camshaft-assembly.htm Sat, 14 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/bearing-sleeve.htm https://www.abiengineeringservice.in/bearing-sleeve.htm Sat, 14 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/direction-sensing-switch.htm https://www.abiengineeringservice.in/direction-sensing-switch.htm Sat, 14 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/oltc-resistance-ring-band.htm https://www.abiengineeringservice.in/oltc-resistance-ring-band.htm Sat, 14 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/olg-oltc-oil-seal-assembly.htm https://www.abiengineeringservice.in/olg-oltc-oil-seal-assembly.htm Sat, 14 Feb 2026 00:00:00 +0530 https://www.abiengineeringservice.in/bakelite-sheet.htm https://www.abiengineeringservice.in/bakelite-sheet.htm Tue, 31 Mar 2026 00:00:00 +0530 We offer high-quality Bakelite Sheets in green color, available in standard sizes with a thickness range of 1-50mm.
