Applications
– Distribution networks
– Capacitor switching
– Frequent switching duties
– Arc furnace duty
– Rapid auto-reclosing
– Switching unloaded transformers and reactors
Salient features
– Extruded / forged electrical grade aluminium for low powerloss and increased reliability
– Sealed for life poles
– Silicon encapsulated vacuum interrupter to reduce possibility of internal flash over
– Application of total contact force throughout the service life even at maximum contact erosion without any maintenance
Pole assembly
– Pole assembly consists of three poles and a common duct
– Each pole comprises of a vacuum bottle, current transfer contacts and an insulating pull rod placed in the porcelain housing
– Robust housing for protection against hazardous conditions
– Primary terminal connectors can be provided, such asNEMA 4
– Poles are interconnected with each other as well as to the operating mechanism with a linkage arrangement
– Simple design - minimizes spare parts
Mounting structure
A robust extruded steel angle structure is used for mounting the breaker which can be extended for mounting current transformers depending on customer requirements.
Base cabinet
The base cabinet is made of painted mild steel with an optionfor stainless steel. The cabinet houses a spring operatedmechanism which is mechanically linked to all three poles.
The cabinet also includes the following:
