Supporting insulator with rhombic core rod

The utility model discloses a supporting insulator with a rhombic core rod, comprising an insulating rhombic core rod, two ends of the rhombic core rod are respectively provided with an upper metal accessory and a lower metal accessory, the rhombic core rod between the upper metal accessory and the lower metal accessory is sleeved with a composite umbrella skirt, and the composite umbrella skirt comprises a plurality of umbrella skirt segments. The umbrella skirt section comprises an annular umbrella skirt and umbrella skirt sleeves arranged at the two ends of the umbrella skirt. The two ends, collinear with the long diagonal line of the rhombic core rod, of the umbrella skirt extend upwards, and the two sides of the umbrella skirt protrude towards the umbrella skirt sleeves on the corresponding sides to form slopes. By adopting the rhombic core rod, the bending resistance and the torsion resistance can be improved, and the structural mass can be reduced so as to reduce the cost; the umbrella skirt structure
