タイトルまたは説明

Introduction:
 
Crompton Greaves Limited (CG) is a pioneering leader in the management and application of electrical energy, with a presence in over *0 countries. CG is active in the global power transmission & distribution (T&D) arena, and is amongst the worlds top ten transformer manufacturers.
The company is organized into four operating divisions viz. Transformers, Switchgears, Systems and Services. The company has full and global responsibility and accountability for their operation in their respective field of responsibility.

Vacuum is proven switching medium with numerous advantages over alternative media & Vacuum Interrupter is the heart of the all switchgear units working with vacuum technology as the process of arc initiation, evolution and extinction take place in the Vacuum Interrupter.

CG started manufacturing of vacuum interrupters at Aurangabad, India in ******6 in technical collaboration with the then Westinghouse Electric, USA, to become the pioneer in vacuum technology in India. After completion of collaboration period, CG extended the product range with continuous design up gradation with in-house research and development to offer vacuum interrupters for various applications. In ******4 CG achieved milestone of manufacturing & selling over 1, *0,**0 VIs & continued its leadership in Indian market. Presently, more than *0, *0,**0 units of CG vacuum interrupters are in service satisfactorily across the globe. CG has mastered in manufacturing vacuum interrupters up to *2.5 kV
