Heavy electric equipment materials
The W-Cu alloy is widely used as a heat
resistant material for the electric arcs
produced when extremely ultra-high voltage
or extra-high voltage circuit breakers
are opened and closed.
The technology to join arc resistant
materials and conductors together
is very important to prevent accidents
resulting from decreases in joining
strength caused by the heat generated
by arcs and the types of joint interfaces
that discharge heat to the outside.
Seunglim Electric Co., Ltd.
has environment friendly manufacturing
technologies including joining methods
composed of FGM(Functional Gradient
Material) layers of ultra high temperature
heat resistant joining materials.
