Features
-
01
Advanced structure
Employs single-arm folding retractable mechanism. Transmission components and balance springs sealed within current-carrying tubes to minimize environmental impact. Compact profile with convenient adjustment via linkage-based transmission base.
-
02
Superior conductive system
Conductive parts utilize high-conductivity aluminum alloy profiles with excellent electrical properties, high mechanical strength, lightweight construction, and corrosion resistance. Foldable arm joints transmit current through flexible shunt connectors (no movable contacts), ensuring reliability with minimal maintenance and long-term service.

03
Plug-in moving contacts
Self-cleaning moving contacts with stainless steel contact springs and insulated isolation spacers. Spring design prevents corrosion/corrosion and current bypass. Arc-striking contacts can be installed on moving/stationary contacts to enable reliable switching of bus transfer currents and capacitive/inductive small currents.
