Product Highlights
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.The rotating contacts Disconnectors transfers the current from the terminal stud to the moving blade through silver plated bronze ball contacts that are housed in a bronze housing and pressed against the stud and housing though a stainless steel spring. The rotating contact construction is completely sealed to ensure maintenance free operationThe contacts are self cleansing type and provided with Dead Centre Mechanism that ensures the locking of Disconnector in both close and open position in case of extreme external forces such as wind force, short circuit force, seismic force etc.
Product Highlights
The base is made of steel plates on which the insulators are mounted. The individual bases are connected by means of a tie rod.
The main blade is made of two aluminum tubes with a hinge in the middle and has silver-plated copper contacts at the jaw end. During closing of the Disconnector, the main blade makes a horizontal stretching movement. Full contact pressure of the main contacts achieved by full stretching of the main blade.
The main contacts are of the reverse-loop design, which makes them suitable for very high short circuit currents. All contact fingers are made of silver-plated copper and are equipped with stainless steel springs to ensure reliable contact pressure.
Product Highlights
The pantograph mechanism is installed on the support insulator and transfers the movement of the operating rod insulator to the arms of the Pantograph Disconnector. The mechanism is housed in an Aluminium enclosure, protecting it from pollution and ice. The springs that compensate the weight of the pantograph arms are also installed inside the housing.
Each Pantograph is equipped with four aluminum arms to ensure a rigid construction with a very high short circuit rating. The main contact arms are made of Aluminium with copper contacts of silver plated surface. The counter contact is a horizontal copper bar, silver plated, which is hung to the bus bar system. The current transfer takes place from the trapeze to the bottom aluminum housing through four arms and number of silver plated bronze ball contacts that are housed in grease packed bronze housing. Disc springs are provided to maintain the contact pressure on the bronze balls against the bronze castings.
The Pantograph Disconnectors are equipped with the dead centre mechanism that ensures the locking of Disconnector in both close and open position in case of extreme external forces such as wind force, short circuit force, seismic force etc.
The Double Break Disconnectors are of simple construction, centre post rotating breaks at both the ends. The three column Disconnectors are mounted on a fabricated steel frame and the rotating post is supported by two ball bearings to ensure smooth operation.
