Under the background of ‘Dual Carbon’

carbon emission is one of the important evaluation criteria for the material selection of cable bracket. However

there is currently a lack of relevant models for calculating carbon emission of cable bracket. In this paper

a carbon emission calculation model for the whole life cycle of cable bracket based on the carbon emission factor method is constructed

in which the impact of brackets’ material consumption and eddy current losses on carbon emission activities is considered. The total consumable material of cable bracket in the whole life cycle is calculated considering the load-bearing performance and corrosion rate of different material

and the eddy current loss is calculated considering the induced current capability of different material and the corresponding carbon emission is calculated in combination with carbon emission factor. Finally

the Xiongdong-Zanxi 220 kV cable project in China is taken as an example

the whole life cycle carbon emission of the line using two different material brackets is calculated. The results show that the carbon emission of 304L stainless steel bracket is much lower than that of Q235 carbon steel bracket. While

304L stainless steel as a new material for cable bracket has good energy-saving and emission reduction effects.
