01
Excellent conductive material
The conductive arm is made of groove shaped aluminum alloy profiles with high conductivity and strength, and has undergone anodizing treatment, which has strong current flow, structural strength, and corrosion resistance.
-
02
New contact finger
Two solutions are available for the contact position, self-propelled contact structure (a high-strength copper alloy) or U-shaped stainless steel spring contact structure. In addition to meeting the general flow requirements, it can also meet the short-time thermal load and electric power load under the short-circuit fault.
-
03
Fully sealed bearing seat
The cast aluminum bearing seat adopts a fully sealed structure, with no loss or solidification of lubricating grease, and no need for oil injection maintenance. The internal structure of the bearing seat adopts a combination support type, and the gravity moment and horizontal force of the product are respectively borne by two special bearings.

04
Maintenance-free transmission
The transmission part of the disconnector is designed according to the requirements of maintenance free, and the self-lubricating sleeve is used with stainless steel shaft pins to ensure that the rotating part does not get stuck.
