SF6 Gas Insulated Sectionalizer

PRODUCTS

APPLICATION

SF6 gas insulated sectionalizer is designed for a self-contained circuit-opening device used in junction with
source-side protective devices such as reclosers and circuit breakers.
It automatically isolate faulted sections of electrical distribution systems.

SF6 gas insulated sectionalizer is designed for a self-contained circuit-opening device used in junction with source-side protective devices such as reclosers and circuit breakers.
It automatically isolate faulted sections of electrical distribution systems.

The sectionalizer has distinct application advantages

• It can be applied between two protective devices having operating curves, which are close together.
  This is a vital feature in a location where an additional step in coordination is not practical or possible.
• It can be used on close-in taps where fault current is highly frequent, coordinating with fuses.
• It has fault close and latch capability for any fault-closing operations.

CHARACTERISTIC

• Easy maintenance and reliable operation
• Compact design and easy installation
• Safety devices (low pressure interlocking, pressure relief, and safety locks)
