Product Description

GLBS-12/24 kV Load Break Switch
1. Brief Introduction
The GLBS is a SF6 load break switch which relies on the chemical properties of SF6 for insulation and arc-quenching. It is a 12-24 kV medium voltage load break switch is designed for applications with indoor and outdoor medium voltage switchgear panels. It consists of a three position rotary switch mechanism mounted and sealed within an epoxy gas tank charged with SF6 gas. It is available as a line switch (AL or BL) or a fuse-switch (BF) with fuse-holders as well as an operating mechanism with tripping capability. Terminals connecting to cables and bus-bars can be of the cone-shaped variety for accommodating silicone bushings on the cable or bus-bar system. Motor operation is optional for the GLBS.

2. The GLBS had the following features:
1. High load breaking capacity (transfer current or maximum breaking capacity of 2600 A)
2. Large creepage distance and superior insulation properties
3. Arc proof and tested for internal arcing
4. Maintenance free or low maintenance requirements
5. Compact dimensions
6. Rugged design ensures long mechanical and electric life
7. Low gas pressure system requiring less than 1kg of SF6 per switch
