SC(B)11 Cast Resin Dry-Type Transformer

Product Overview

The SC(B)11 epoxy-resin cast dry-type transformer optimizes the core and winding design on the SC(B)10 platform, further reducing loss and noise — the mainstream series balancing performance and cost for building and industrial power distribution. HV and LV coils are cast under vacuum and pressure, giving the resin insulation full encapsulation combined with inter-turn impregnation.

Key Features

• Low partial discharge: advanced resin mixing plus vacuum-film degassing removes bubbles completely;
• Flame-retardant and explosion-proof: glass-fiber insulation is self-extinguishing and the resin releases no toxic gases at high temperature;
• High mechanical strength: filled resin minimizes expansion mismatch and curing shrinkage; prefabricated reinforcement inside the encapsulation gives strength above pure epoxy, withstanding sudden short-circuit forces;
• Optional temperature control system with axial fans for forced-air overload capacity.

Typical Applications

Indoor distribution in high-rise buildings, commercial centers, rail transit and industrial plants.
