LCA study of HV Circuit Breaker
The Life Cycle Assessment (LCA) for the LTB-D 145 kV high voltage circuit
breaker is performed to make an Environmental Product Declaration (EPD). The
report is conducted according to the recommendations and requirements given in
the ISO 14040 series of LCA standards and the LCA fulfills the requirements of a
certified EPD according to ISO TR 14025.
- The usage phase dominates the environmental impact of the breaker.
- Epoxy is, together with SF6, on ABB´s restricted list of hazardous
- Easy dismantling and separation of materials will facilitate recycling and
decrease the environmental impact from the materials.
- SF6 has an extremely high influence on the global warming potential,
therefore, a minimum of leakages and a secure gas recovery at dismantling
are of outmost importance.
