Products
From transformers to complete switchgear
SCBH19
Rated capacity:
30–2500 kVA
Voltage class:
10 kV / 0.4 kV

SCBH19 Amorphous-Alloy Dry-Type Transformer
Amorphous-alloy dry-type transformer meeting the Chinese Grade 1 efficiency standard, with vacuum-cast epoxy insulation and 15%–30% lower no-load loss.
SBH25
Rated capacity:
30–2500 kVA
Voltage class:
10 kV / 0.4 kV

SBH25 Amorphous-Alloy Oil-Immersed Transformer
Amorphous alloy wound core in a fully sealed corrugated tank; no-load loss is about one third to one quarter of a comparable S13 silicon-steel unit.
GCS
Rated voltage:
AC 380 V / 660 V, 50/60 Hz
Rated current:
≤ 4000 A

GCS AC Low-Voltage Withdrawable Switchgear
Withdrawable LV switchgear assembly for 50/60 Hz, 380/660 V networks up to 4000 A, used for incoming and feeder circuits and centralised motor control.
YBM
Rated capacity:
to order
HV rating:
to order

YBM Prefabricated Box Substation (European-Style)
Factory-built assembly of HV switchgear, distribution transformer and LV switchgear in a fully enclosed steel housing: small footprint, safe operation.
Applications
Efficient power for grids and industry.
Coreda supplies distribution areas and industrial parks with low no-load loss, maintenance-light equipment for urban distribution networks, energy storage, power facilities, high-speed rail and wind power.

Urban Distribution Networks
Urban grids are built from large numbers of 10 kV substations that stay energised around the clock, so no-load loss accounts for a significant share of annual energy losses. Coreda combines amorphous-alloy transformers with prefabricated substations to place low-loss, low-noise equipment inside residential and commercial load centres.
Typical equipment:
- Amorphous-alloy transformers
- Prefabricated substations
- Ring-main supply
- Indoor substation rooms
Energy Storage
A storage plant cycles between charging, discharging and standby every day, and the transformer stays energised through standby, so its no-load loss is charged straight to auxiliary consumption. Coreda configures the step-up unit with fully sealed amorphous-alloy transformers, compact substations and withdrawable LV switchgear to keep auxiliary consumption and site work down.
Typical equipment:
- Amorphous-alloy transformers
- Pad-mounted substations
- Withdrawable LV switchgear
- Containerised step-up units
Wind Power
Wind turbines stay connected to the grid through low-wind and standstill periods, leaving the step-up transformer at no load or light load for long stretches, and the equipment is spread across an unattended site. Coreda delivers the step-up unit as a complete box-type substation, with amorphous-alloy or low-loss silicon-steel transformers inside to limit site losses and inspection work.
Typical equipment:
- Box-type substations
- Amorphous-alloy oil-immersed transformers
- 35 kV collection
- Salt-fog and dust protection
High-Speed Rail
Substations serving station buildings and lineside facilities usually sit on basement levels or in enclosed plant areas, where fire protection, noise and access for maintenance are all constrained. Coreda organises station supply around amorphous-alloy dry-type transformers and modular MNS withdrawable LV switchgear, for flame retardance, efficiency and work inside the night window.
Typical equipment:
- Amorphous-alloy dry-type transformers
- Class H flame-retardant insulation
- Modular LV switchgear
- Basement substations
