Hermetically Sealed Transformer Manufacturing
Hermetically sealed oil-filled distribution transformers are built in a fully closed tank, typically with a gas cushion instead of an open conservator. They tolerate outdoor moisture and contamination better. Common on distribution feeders and industrial supply points. Rating and voltage class follow the project brief.
Hermetically Sealed Oil-Immersed Distribution Transformer
MBB Hermetically Sealed Oil-Immersed Distribution Transformers are manufactured in accordance with international standards to deliver high energy efficiency, long service life, and reliable performance.The hermetically sealed tank prevents the insulating oil from contacting ambient air, minimizing moisture ingress and extending transformer lifetime while reducing maintenance requirements. These transformers are ideal for industrial plants, power distribution networks, commercial buildings, infrastructure projects, and renewable energy applications.FeaturesPower ratings from 50 kVA to 5000 kVAOperating voltage up to 36 kVLow-loss, high-efficiency designMaintenance-free hermetically sealed constructionManufactured in accordance with IEC 60076High short-circuit withstand capabilityReliable, long-lasting performance for demanding applications
Used Transformer Supply
Supply of used or refurbished distribution and power transformers. Ratings, voltage and physical condition are checked before matching stock or sources. Overhaul, oil analysis or rewind needs are assessed separately. Useful for budget spare units and temporary supply.
Cast Resin Dry-Type Transformer (5 kVA – 3150 kVA)
MBB Cast Resin Dry-Type Transformers are engineered to deliver maximum safety, energy efficiency, and reliable performance for industrial facilities, commercial buildings, hospitals, data centers, renewable energy plants, and critical infrastructure.The epoxy resin insulated windings provide excellent resistance against moisture, dust, chemicals, and harsh environmental conditions. Their oil-free construction minimizes fire risk while significantly reducing maintenance requirements.Manufactured according to IEC 60076-11, MBB dry-type transformers ensure low losses, high efficiency, and long operational life.Technical SpecificationsPower Rating: 5 kVA – 3150 kVAVoltage Class: Up to 36 kVFrequency: 50 / 60 HzInsulation: Cast ResinCooling: AN / AFProtection Class: IP00 – IP23 (Optional)Low-loss designMaintenance-free operationLow noise levelManufactured according to IEC 60076-11ApplicationsIndustrial PlantsManufacturing FacilitiesData CentersHospitalsShopping MallsHotelsMetro & Railway SystemsWind Power PlantsSolar Power PlantsPublic BuildingsCommercial ComplexesHigh-Rise Buildings
Dry Type Transformer Manufacturing
MBB Trafo manufactures dry-type (cast-resin / isolated) distribution transformers. Typical ratings serve LV/MV distribution panels in ventilated or indoor switchgear rooms. Oil-free construction suits sites with stricter fire constraints. Units are built to the buyer’s voltage, power and protection-class specification.
New Transformer Supply
Supply of brand-new distribution and power transformers, covering dry-type, oil-immersed and hermetic options. Power, voltage and connection group are matched to the buyer specification. Factory tests and documentation can be planned before delivery. Suited to industrial plants, construction feeds and grid renewal projects.
Oil-Immersed Transformer Manufacturing
Oil-immersed distribution and power transformers use mineral or dielectric oil for cooling the windings. They serve utility feeders, industrial plants and OSB substations. Power rating, voltage ratio and vector group follow the order specification. Tank, radiators and protection gear are selected per application.
Services
Custom Winding and Coil Work
Custom winding and coil work covers transformer rewind, enamelled-wire coil manufacture and repair. Failed or end-of-life units can be assessed for winding replacement. Power, voltage and insulation class follow the existing core or a new design. Workshop-based special manufacturing and overhaul.
Custom Transformer Manufacturing
MBB Trafo builds custom power and distribution transformers to the buyer specification. Voltage ratio, vector group, impedance, protection class and mechanical envelope are set per project. Dry-type, oil-immersed or hermetic designs can be selected. Aimed at OEM and special-build needs.
Transformer Buy and Sell
Buy-and-sell service for new and used distribution/power transformers. Buyer needs are filtered by power, voltage and type (dry, oil, hermetic). Seller stock or dismantling sources are assessed. Supports fast spare cover and plant or grid renewal projects.
