Engineered Without Compromise
Inaugurating in 2026, ZC Technology's dedicated high-voltage transformer manufacturing facility integrates automated core slitting, step-lap magnetic stacking, multi-strand foil winding, and vacuum epoxy pressure encapsulation.
Whether deployed in high-density metropolitan residential basements requiring flame-retardant dry-type units or outdoor renewable utility substations requiring hermetically sealed oil-immersed units, ZC transformers comply with the latest China National GB 20052-2020 Level 1 and Level 2 energy efficiency standards.
Up to 25% reduction in no-load magnetic core losses compared to traditional legacy units.
Operating noise levels controlled to under 48 dBA through silicone rubber damping pads.
