    The Fact about Alu-Zinc Steel

    90% of Metallic Parts of SecoGear are utilizing Alu-Zinc Steel

    Alu-Zinc Steel is 3-7 times longer lifetime than Hot Dip Galvanized steel

    Good environment choice

    Alu-Zinc surface is twice harder

    SecoVac Embedded Pole VCBTechnology Challenge

    Main technical challenge of embedded pole technology

    The cracking of embedded pole caused by the different heat coefficient multiplier between ceramic tube and the epoxy resin (Ceramic : Epoxy Resin = 1:10)

  • 30 /GE Consumer & Industrial /

    5/20/2008

    SecoVac Embedded Pole VCBInnovative Technology

    Solution:A special cushion layer made of high insulation, gas tight and strong elastic material was employed around the surface of the ceramic tube of vacuum interrupter before it was embedded, so the cracking is thoroughly avoided.
