11KV & 33KV PCVCB

PCVCB, or Polymer Clad Vacuum Circuit Breaker, from Arpan Power Projects is a reliable outdoor circuit breaker for 11KV and 33KV medium-voltage networks. It combines vacuum interruption technology with polymer insulation to deliver high interrupting capacity, safe fault clearing and very low maintenance. Our PCVCB is built for demanding outdoor conditions and can be configured to match your system rating and protection needs.

What Is a PCVCB?

A PCVCB is a vacuum circuit breaker whose poles are insulated with polymer material. When a fault occurs, the contacts open inside a sealed vacuum chamber and the arc is extinguished quickly, which protects the line and the connected equipment. The polymer insulation is lightweight, resists weather and pollution, and helps the breaker perform reliably outdoors.

How Does a Polymer Clad Vacuum Circuit Breaker Work?

Under normal conditions the contacts inside the vacuum interrupter stay closed and carry the load current. During a fault, the operating mechanism opens the contacts, and an arc forms for a brief moment in the vacuum. Because there is no gas to sustain it, the arc is extinguished at the first current zero, and the circuit is isolated quickly. The polymer cladding insulates and protects the interrupter, helping the breaker stay reliable in outdoor conditions.

Key Features of 11KV PCVCB and 33KV PCVCB

• Vacuum interruption technology for fast and dependable fault clearing
• Polymer insulation that resists weather, dust and pollution
• High interrupting capacity for medium-voltage distribution networks
• Low maintenance requirement and long service life
• Lightweight, compact construction for easy handling and installation
• Available for both 11KV and 33KV systems
• Ratings and protection can be customised to your project

Benefits of Polymer Clad Vacuum Circuit Breakers

Using a PCVCB improves the safety and reliability of your outdoor network. The sealed vacuum interrupter needs far less servicing than older oil or air-based breakers, which cuts downtime and running cost. Polymer insulation is lighter than traditional materials, so the breaker is easier to transport and install. Together, these advantages make it a cost-effective choice for utilities, industries and renewable energy projects that need dependable protection over many years.
