The invention discloses a multi-stranded semi-foamed monitoring coaxial cable with small consumable usage. The multi-stranded semi-foamed monitoring coaxial cable comprises a multi-stranded inner conductor, a semi-foamed insulator arranged at the outer side of the multi-stranded inner conductor, a shielding layer arranged at the outer side of the semi-foamed insulator and a protective sleeve arranged at the outer side of the shielding layer. The multi-stranded semi-foamed monitoring coaxial cable has the advantages that semi-foaming treatment is carried out on the insulator in the production process; the raw and auxiliary materials can be greatly reduced by using a semi-foaming technology; resources are saved; the multi-stranded semi-foamed monitoring coaxial cable responds to the national call of energy conservation and emissions reduction; signal attenuation in the cable can be effectively controlled; the signal transmission performance is good; the flame retarding effect is good; and whether the insulator is damaged or not can be detected and the insulator can be timely repaired, so that an accident is reduced.
