Given that carbon footprint of product (

CFP

) is becoming a new dimension for product evaluation

the

CFP

of six kinds of publicly available 12 kV switchgear cabinets from two companies is taken as the base

the carbon footprint of such three representative insulation modes as air insulation

SF

6

gas insulation and environmentally-friendly gas insulation at different boundaries and stages are compared and analyzed

showing that

CFP

is mainly concentrated in the stages of raw material acquisition and product usage

accounting for approximately 80%-92.5% in total. Due to the influence of product structure

insulation method and gas dielectric

the

CFP

of the environmentally-friendly gas-insulated and SF

6

-insulated switchgear cabinets is 31%-35% of that of air-insulated switchgear cabinet

and that of the environmentally-friendly gas-insulated switchgear cabinet is lower than that of SF

6

-insulated switchgear cabinet by 8%-12.5%. It is pointed out through the simplified comparison and analysis of

CFP

and main constituted material of the two stages that not only the

CFP

during the raw material acquisition and product use stage

but also the

CFP

product are basically determined by the product design

therefore the product design needs to balance and optimize these two main stages in order to reduce the

CFP

. It is pointed out further that the material usage efficiency of domestic products still needs to be improved. The comparison

evaluation and selection of product is achieved better through

CFP

and it is suggested setting up unified comparison evaluation mode complying with the attachment B of GB/T 24067—2024.
