Centre Break Disconnectors

We manufacture and supply a Centre Break Disconnectors in Hyderabad, Telangana, India.

The horizontal Centre Break Disconnector is of simple design of two post rotating contacts, with break at the Centre, used in outdoor high voltage Sub-station. The two column Disconnector are mounted on a fabricated steel frame, supported by two ball bearings to ensure smooth operation.

BASE ASSEMBLY :
The base frame is made out of a fabricated steel structure designed to withstand all the external forces like wind load, dead weight of Insulator & contacts, short circuit force and seismic force etc. Both the rotating post is supported by two nos. ball bearing one at top & one at bottom of the bearing housing with adequate distance between them to avoid wobbling of Insulator

CONTACTS :
The main Contact consists of a U- Shaped tube, in which the main contacts and the rotating contacts are installed. The U-shaped tube is either Copper/Aluminium with copper contact fingers plated with silver. Each contact fingers is provided with stainless steel springs to ensure reliable contact pressure.

The jaw and fist type contacts are so designed that the current transfer takes place through multi-point contacts that are equipped with stainless springs, which ensure low contact resistance. Wiping action carried out during closing & opening of isolator and the design ensures low operational torque and smooth & effective closing of contacts.
