The invention relates to an anti-ice-flashover composite insulator with a lightning protection function, which comprises a mandril (2), and a casing (9) thereof is provided with a first composite umbrella cover (3). The mandril (2) in a cylinder is sleeved with stacked metal oxide valve plates (8) and a spring (7). The lower end of the mandril (2) is provided with a second composite umbrella cover (4). The upper end of the second composite umbrella cover (4) is sleeved with a first strap (11), and the lower end thereof is provided with a second strap (12). A bowl-shaped metal cap (1) and a ball-shaped metal cap (5) are respectively covered on both ends of the mandril (2). In freezing days, the insulator can prevent ice covering and blocking arc serial connection, and greatly reduces the possibility of line trip. The invention has the beneficial effects that: (1) the bearing load for the whole mandril to suspend a transmission conductor is higher; (2) a lightning protection section bears lower voltage; (3) the metal oxide valve plates contact tightly; (4) the lines prevent lightning; and (5) an umbrella skirt string structure insulating outer cover which comprises staggered and laminated large and small umbrella skirts can prevent ice flashover in freezing weather.
