Fabricated cable duct bank with low-carbon core and production process thereof

The invention relates to the technical field of underground prefabricated cable line structure engineering of an electric power engineering power distribution network, and particularly discloses an assembly type cable duct bank with a low-carbon core and a production process of the assembly type cable duct bank. The fabricated cable duct bank comprises a cable protection tube, a steel reinforcement framework, a concrete package and a low-carbon core, wherein the steel reinforcement framework is embedded in the concrete package; the cable protection pipe and the low-carbon core are both embedded in the concrete package and located in the steel reinforcement framework. The number of the cable protection pipes is multiple, two ends of each cable protection pipe are provided with horn-shaped openings convenient for penetration of cables, and the outer walls of the multiple cable protection pipes are all attached to the surface of the arc-shaped groove of the low-carbon core. The cable protection pipe is positione
