The invention provides a section insulator, relates to the technical field of electrified railway contact networks, and aims to solve the problem that conductive slide rails are burnt and damaged due to the fact that discharge is easily generated between the conductive slide rails of the section insulator to a certain extent. The invention provides a section insulator. The section insulator comprises an insulator main body, a first conductive assembly and a second conductive assembly, the first conductive assembly and the second conductive assembly on the same side of the insulator main body are oppositely arranged, the first conductive assembly comprises a first conductive slide rail and a first arc extinguishing ring, and the second conductive assembly comprises a second conductive slide rail and a second arc extinguishing ring; the opening part of the first arc extinguishing ring and the opening part of the second arc extinguishing ring are oppositely arranged, the port of the first arc extinguishing ring and the end face of the first conductive sliding rail are located on the same vertical plane, and the port of the second arc extinguishing ring and the end face of the second conductive sliding rail are located on the same vertical plane. And the minimum distance between the first arc extinguishing ring and the second arc extinguishing ring is not greater than the distance between the end surfaces of the first conductive slide rail and the second conductive slide rail.
