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.
