Abstract
A section insulator for a tramcar comprises a pair of mounting bases, an upper insulator body, a lower insulator body, a pair of connection clamps, a pair of long slide ways, a pair of short slide ways and a pair of contact line hanging clamps. The upper insulator body and the lower insulator body are connected and fixed between the mounting bases. The connection clamps are horizontally connected to the rear sides of the mounting bases and are fixedly mounted at the ends of contact lines. The long slide ways and the short slide ways are arranged on two sides of the mounting bases in a staggered mode. The middles of the long slide ways and the middles of the short slide ways are fixed to two sides of the mounting bases respectively. The tails of the long slide ways and the tails of the short slide ways are connected and fixed to the contact lines through the contact line hanging clamps. The section insulator has the advantages that through the structural mode of the upper insulator body and the lower insulator body, stability of the section insulator is improved; the insulator bodies are glued and riveted to the mounting bases, so that structure is simplified, and weight is reduced; in addition, main body components of the section insulators can be installed and debugged in place before delivery, secondary adjustment is not needed during on-site mounting, mounting steps are simplified, and mounting difficulty is lowered.
