Custom SCB14 20 kV Three-Phase Epoxy Resin Cast D | RFQ Sourcing Details

This SCB14 three-phase dry-type distribution transformer is designed for power transformation and distribution duties. The supplied identifies a 20 kV series with listed capacities from 30 to 2,500 kVA and also describes broader 10 kV, 20 kV, and 35 kV product grades.

Buyers should confirm the exact voltage class, rated capacity, vector group, tapping arrangement, and secondary voltage for each project. The transformer uses epoxy resin vacuum-cast coils and an F(H)-class heat-resistant insulation system.

Its described construction includes a compact integral cast-coil structure intended to resist cracking. Because it is oil-free, it avoids the oil-leakage considerations associated with liquid-filled transformer designs.

The listed technical characteristics include low partial discharge, high insulation reliability, and low-maintenance operation;project-specific test values and acceptance limits should be agreed before ordering.

Published SCB14/20 table entries cover 200, 250, 315, 400, 500, 630, 800, 1,000, 1,250, 1,600, 2,000, and 2,500 kVA. The same table also includes SC14 entries at 50, 100, and 160 kVA. Listed impedance voltage is 6% through most of the range, while separate 2,000 and 2,500 kVA entries show 8% configurations.

Listed IP00 and IP20 dimensions, losses, noise levels, weights, and track spacing vary by rating and configuration. Customization is stated to be available for voltage, frequency, operating environment, packaging, and sample-based requirements, with OEM and ODM service offered.

The product information lists indoor and outdoor suitability and an ambient-temperature range of -40°C to +40°C.

Buyers should not assume that one enclosure or environmental configuration covers every installation;confirm ingress protection, ventilation, temperature-rise limits, altitude, humidity, pollution level, seismic requirements, and installation location.

Before procurement, request a model-specific technical schedule and drawing.

Confirm rated primary and secondary voltages, frequency, capacity, phase arrangement, vector group, impedance, tap range, enclosure rating, cooling designation, insulation and temperature-rise limits, accessory package, cable-entry arrangement, footprint, total mass, losses, noise limit, and required routine or type tests.

The source information contains an inconsistent attribute describing an oil-immersed cooling method despite identifying the product as an epoxy resin cast dry-type transformer, so the final cooling designation should be resolved in the approved datasheet.
