Power Industry (Generation & T&D)

Overview

From thermal and hydro to regional distribution grids, CHBEST's oil-immersed transformers, dry-type transformers, and HV switchgear cover the full chain: generation-side step-up, substation step-down, and end-user distribution. Prefabricated E-House substations enable plug-and-play outdoor deployment, slashing construction lead times — ideal for rapid grid rollout in Southeast Asia and Africa.

 Power Plant Step-Up Substation

Pain Point:

Generator output at 10.5kV–20kV must be stepped up to 110kV/220kV for grid interconnection.

Products:

Oil-immersed power transformers (S11/S13 series), HV switchgear (KYN28).

Flow:

Generator → Isolated Phase Bus → Step-Up Transformer → HV Switchgear → Transmission Line.

 Regional Substation

Pain Point:

110kV/35kV incoming must be stepped down to 10kV/0.4kV for urban distribution.

Products:

On-load tap-changing oil transformers, RMU ring main units, MV switchgear.

Flow:

HV Incoming → Main Transformer → MV Switchgear → Feeder RMUs → End Users.

 Rural Grid Upgrades

Pain Point:

Scattered loads, long transmission lines, high losses.

Products:

Amorphous alloy transformers (70% lower no-load losses), compact RMUs.

Flow:

35kV Line → Amorphous Transformer → Pole-Mounted Switch / Compact RMU → LV Distribution.
