VBI-12 Side-mounted indoor hv vacuum circuit breaker

Model: VBI-12

Description

VBI type vacuum circuit breaker conforms to national standard GB1984-2003 HV Vacuum Circuit Breaker, JB3855-1996<3.6-40.5kV indoor AC high voltage vacuum circuit breaker>, DL/T403-2000<12kv-40.5kv HV vacuum circuit breaker ordering technical conditions>, and IEC62271-100:2001 high voltage AC circuit breaker relevant regulations.

Outstanding Features Make You Stand Out

We play extreme caution to quality and utmost attention to detail, which makes our products so perfect.

    Modularization of Functional Unit

    The main circuit unit and running product are coherent in interchangeability.

  • administration.icon02
    Strong Versatility

    The operating mechanism can be separated from the whole circuit breaker for convenient and easy maintenance and fix.

  • administration.icon02
    Low Maintenance

    No need of adjustment of driving unit; long-acting lubricating, reliable corrosion resistance, and high mechanical stability make low maintenance possible.

  • administration.icon02
    Long-acting Lubricating

    We apply German lubricating grease boasting lower starting torsion, stronger anti-aging and oxidation resistance.

  • administration.icon02
    Strong Corrosion Resistance

    Utilizing zinc-nickel alloy plating line with a German process to make sure our corrosion resistance is 5 to 7 times stronger than ordinary zinc-plating process.

  • administration.icon02
    Strong Expandability

    This product can easily realize diverse arrangements and combinations to meet functions like expandability and control.
