Product Overview:

At Hi-Volt Switchgears, we offer a wide range of CG Vacuum Interrupters that are trusted for high-performance and long-term reliability in medium-voltage switchgear applications. With models such as the 11kV 34599 M3+ and 11kV 33379 M3+, these interrupters are suitable for use in circuit breakers, vacuum contactors, and reclosers.

The Vacuum Interrupter (VI) serves as the core component of a circuit breaker, responsible for arc extinction and current interruption. Designed for reliability and high performance, this 11kV vacuum interrupter from Crompton Greaves is engineered to deliver consistent operation under demanding conditions.

Every component of the interrupter is the result of extensive research and development carried out by CG’s advanced R&D team. Special attention is given to optimizing the high-voltage performance using electrostatic analysis during the design phase, ensuring effective insulation, compact size, and long service life.

Built with ceramic materials for enhanced durability and electrical strength, this interrupter is ideal for use in medium-voltage switchgear, offering stable arc-quenching capabilities, excellent dielectric properties, and minimal maintenance requirements.

Key Features

• High Interrupting Capacity: Efficient arc quenching ensures safe interruption even under heavy load conditions.

• Compact Design: Space-saving structure with robust mechanical integrity for various installations.

• Superior Dielectric Strength: Polyurethane and silicon encapsulation enhances external insulation and safety.

• Long Life & Reliability: Built for endurance with low maintenance needs.

• Low Chopping Current: Reduces overvoltage during inductive load interruptions.

Uncompromised Quality

CG vacuum interrupters are manufactured under strict quality control systems. These interrupters comply with IS, IEC, and ANSI standards and are certified with the latest ISO 9001, ISO 14001, and OHSAS 18001 certifications. Each unit undergoes rigorous testing to ensure optimal dielectric performance, mechanical durability, and safety.

Advanced Research & Development

CG began its journey in vacuum technology in 1985-86 in collaboration with Westinghouse Electric, USA. Since then, continuous in-house R&D has led to the expansion of their interrupter range up to 72.5kV. The dedicated R&D facility focuses on improving performance, life cycle, and material technology, making CG one of the largest vacuum interrupter manufacturers in India with over 1.5 million units deployed globally.
