Features
-
01
Advanced structure
The product adopts single-arm folding and telescopic structure, transmission components and balance spring are sealed in the conductive tube, reducing the impact of natural environment on the product, compact and simple appearance. Transmission base adopts connecting rod structure, easy to adjust.
-
02
Excellent conductive system
The conductive part is made of aluminum alloy profiles with high conductivity, good conductivity, high strength, light weight and strong anti-corrosion ability. The current in the folding part of the conductive arm is transmitted through the soft connection, there is no active contact, and the conduction is reliable, achieving less maintenance, no inspection and long-term reliable operation.
-
03
Stable static contact structure
The hanging static contact is fixed by pure aluminum hinge wire ring, with high flow capacity. At the same time, the static contact is fixed by the steel rope triangle suspension, easy adjustment, good stability, and can reduce the displacement of the static contact head.
-
04
Features clip-on contacts
The contact head is clamp type, and the external pressure spring is added to the moving contact knife to ensure constant contact pressure. The lower end of the contact knife is connected with the contact seat for soft connection, no active contact point, reliable conduction, to avoid overheating caused by poor contact.
