AI Technical Summary

Problems solved by technology

[0006] The conductive parts inside the pipeline need to use conductive materials with very low resistivity. The high-temperature superconducting materials required for power transmission in LNG shared pipelines are currently difficult to form into a line, resulting in high costs. In addition, the insulating support inside the LNG pipeline The skeleton needs materials that can withstand the low temperature of LNG, so its cost is also high

[0007] That is to say, the overall cost of the power transmission system in the prior art is too high due to the high manufacturing cost of the conductive part and the insulating support frame suitable for the superconducting energy pipeline

[0008] In addition, directly adding high-voltage wires inside the pipeline for power transmission may also affect the ground potential of the shared pipeline, especially in the case of a ground short circuit, the large current of the pipeline to the ground will affect or even destroy the pipeline potential monitoring and anti-corrosion measures
