Features
-
01
Advanced structure
Employs single-arm folding pantograph design. Transmission components and balance springs are sealed within current-carrying tubes to minimize environmental impact. Compact profile with linkage mechanism base for convenient adjustment.
-
02
Premium conductive system
Conductive parts utilize high-conductivity aluminum alloy profiles ensuring excellent electrical performance, high mechanical strength, lightweight construction, and superior corrosion resistance. Current transmission at folding joints achieved through flexible shunts without movable contacts, guaranteeing reliability while enabling minimal maintenance and long-term inspection-free operation.
-
03
Stable static contact structure
Suspended static contact secured by pure aluminum stranded wire ring for enhanced current-carrying capacity. Triangular steel-cable suspension provides convenient adjustment, superior stability, and minimized vertical displacement.
-
04
Unique clamp-type contact
Features scissor-type contact mechanism. Moving contact blade incorporates external compression spring to maintain constant contact pressure. Blade lower end connects to contact seat via flexible shunts (eliminating movable contact points), ensuring reliable conductivity and preventing overheating from poor connections.
