6-35kV SC(B) Series Epoxy Resin Insulated Dry-type Transformer

Product Introduction

• The SC(B) Series Epoxy Resin Cast Dry-type Transformer is a high-performance, safe, and reliable dry-type distribution transformer. It features full epoxy resin cast insulation, thin insulation high-voltage windings, high mechanical strength, low partial discharge, excellent short-circuit resistance, and superior lightning impulse performance. The coil surfaces are smooth and aesthetically pleasing, with natural material color, giving the transformer an elegant appearance.
• This series of transformers is compact, lightweight, and maintenance-free, requiring no oil pits or fire protection facilities. It is particularly suitable for urban power grids, high-rise buildings, commercial centers, theaters, hospitals, hotels, subways, stations, docks, airports, and other critical public and industrial installations.

Application Scenarios

• The SC(B) Series Epoxy Resin Insulated Dry-type Transformer is widely used in urban power grids, commercial buildings, residential complexes, industrial facilities, and public infrastructure where high safety, fire resistance, and environmental protection are required.
• It is especially suitable for indoor installations such as high-rise buildings, airports, hospitals, subways, and data centers, as well as applications with strict requirements on reliability and low maintenance.

Product Features

• 1. High-voltage Windings
• Manufactured using impregnated epoxy resin with vacuum casting, ensuring low partial discharge and high electrical strength.
• The inner and outer winding surfaces are reinforced with fiberglass mesh, improving mechanical strength and short-circuit resistance.
• Coils are fully cured and crack-resistant, ensuring safety and reliability.
• 2. Low-voltage Windings
• Foil-type structure ensures balanced ampere-turns.
• Axial cooling ducts enhance heat dissipation.
• Interlayer insulation uses DMD epoxy resin prepreg, fully cured to form a solid structure.
• 3. Core
• Made of imported high-quality cold-rolled silicon steel with three-stage full-step-lap joints.
• Core limbs are bound with F-class strap and epoxy-coated, reducing no-load loss, no-load current, and core noise.
• Core clamps and fasteners are surface-treated for durability and aesthetics.
• 4. Temperature Control and Cooling System
• Axial-flow top-blowing fans with low noise and high air pressure enhance overload capability.
• Intelligent temperature controllers monitor transformer temperature for safer and more reliable operation.
• 5. Enclosure and Output Design
• Enclosure options: IP20 or IP23, with materials including aluminum alloy, cold-rolled steel, or stainless steel.
• Flexible LV output options: side exit, top exit, or custom designs to meet user requirements.
