The application discloses a tension type impressed current
cathodic protection system, which comprises a composite cable made of a steel core aluminum stranded wire with an outer sheath, a first insulation connecting structure arranged at the upper end of the composite cable and used for insulatingly connecting the composite cable with a member to be protected, a cable
branch structure arranged at the upper end of the composite cable and used for electrically connecting the composite cable with a
power control cabinet, an auxiliary
anode arranged on the composite cable and used for releasing current, and a second insulation connecting structure arranged at the lower end of the composite cable and used for insulatingly connecting the composite cable with a gravity foundation. The tension type impressed current
cathodic protection system disclosed by the application has the advantages of light weight and low price compared with the existing composite cable
copper as a power line under the same current carrying requirement, and the production
processing technology of the steel core aluminum stranded wire is simplified as the steel core aluminum stranded wire only needs to be coated with a wear-resistant sheath.
