Manufacturing source: Baoding Zhongyi Electric Group Co., Ltd. — Supplier Profile

Equipment overview

Built around the confirmed duty

The official page identifies NOMEX paper as the principal insulation material and describes H-class or higher C-class insulation options. The source also identifies VPI vacuum-pressure impregnation, open construction for heat dissipation, moisture resistance and improved electrical and short-circuit performance.

Working principle

The core and windings transfer power through electromagnetic induction. NOMEX insulation and VPI impregnation provide the dry insulation system, while the open construction supports air cooling.

Power and transmission equipment selection is based on power or torque, speed, load profile, service factor, electrical supply, mounting, environment, efficiency and integration requirements.

Core features

  • Open structure for effective heat dissipation
  • VPI vacuum-pressure impregnation
  • Source-described moisture resistance and short-circuit capability
