Heavy machinery, mining crushers, and metallurgical arc furnaces produce severe harmonics and load surges that push transformers and switchgear to their limits. CHBEST's high-impedance transformers, GGD LV switchgear, and capacitor compensation banks tackle voltage sag and harmonic pollution, keeping production lines running non-stop.
Pain Point:
Generator output at 10.5kV–20kV must be stepped up to 110kV/220kV for grid interconnection.
Products:
Oil-immersed transformer (high-impedance type), GGD LV switchgear, capacitor compensation cabinet.
Flow:
35kV/10kV Incoming → Main Transformer → HV Switchgear → Workshop Transformer → LV Switchgear (with compensation) → Motor Control Center (MCC).
Pain Point:
110kV/35kV incoming must be stepped down to 10kV/0.4kV for urban distribution.
Products:
Prefabricated E-House substation, mobile package substation.
Flow:
HV Incoming → Main Transformer → MV Switchgear → Feeder RMUs → End Users.
Pain Point:
Explosion-proof requirements, corrosive environments, high-capacity arc furnace surges.
Products:
Epoxy-resin cast dry-type transformer, anti-corrosion switchgear.
Flow:
35kV Line → Amorphous Transformer → Pole-Mounted Switch / Compact RMU → LV Distribution.
