scb10-100kva Dry-type Transformer

The resin-insulated dry-type transformers are independently developed by our company by introducing advanced

foreign technologies, including SC9, SCB9 series and SC10, SCB10 series dry-type transformers with filled thin

insulation. As the coils are encapsulated by epoxy resin, they are flame-retardant, fireproof, explosion-proof,

maintenance-free, pollution-free, and compact in size, allowing direct installation at the load center. Meanwhile, the

scientific and reasonable design as well as casting process enable the products to have lower partial discharge, low

noise, and strong heat dissipation capacity. Under forced air cooling conditions, they can operate continuously at

140% of the rated load for a long term. Equipped with an intelligent temperature controller, they feature functions

such as fault alarm, over-temperature alarm, over-temperature tripping, and black box, and can be connected to a

computer via an RS485 serial interface for centralized monitoring and control.

Due to the above characteristics, the dry-type transformers of our company are widely applied in power transmission

and distribution systems, such as important venues like hotels, airports, high-rise buildings, commercial centers, and

residential communities, as well as harsh environments such as subways, thermal power plants, ships, and offshore

drilling platforms.

10–20kV Resin Cast Dry-Type Distribution Transformer – Safe, Smart & Space-Saving Power Solution

The 10–20kV Resin Cast Dry-Type Distribution Transformer (e.g., SCB10-100kVA) is engineered for modern indoor Power Systems where safety, reliability, and compact design are critical. Fully encapsulated in flame-retardant epoxy resin, its windings are immune to moisture, dust, and mechanical stress—making it ideal for installation directly in load centers such as high-rises, hospitals, data centers, airports, and underground facilities.

Featuring low partial discharge (<10 pC), minimal noise levels, and excellent thermal performance, this transformer supports continuous operation at **140% rated load under forced air cooling**. An integrated intelligent temperature controller provides over-temperature alarms, automatic tripping, fault logging (“black box”), and RS485 connectivity for remote monitoring—enabling predictive maintenance and smart grid integration.

Flame-retardant dry-type power transformer – eliminates fire hazards and oil leaks, suitable for densely populated or sensitive environments
Indoor 10kV cast-resin distribution unit – compact footprint allows direct placement near end-users without dedicated transformer rooms
Smart-monitored F-class insulation transformer – combines Class F (155°C) thermal rating with digital diagnostics for enhanced uptime

Available in capacities from 10kVA to 4000kVA, with standard configurations like Dyn11 or Yyn0 and tap ranges of ±2×2.5%, the SC(B)10 series meets IEC 60076 standards and delivers ultra-low no-load and load losses—reducing energy consumption and operational costs over its service life.

Whether deployed in commercial complexes, industrial plants, or marine platforms, this dry-type transformer offers a maintenance-free, eco-friendly, and future-ready solution for safe and efficient medium-voltage power distribution.
