Summary:The utility model discloses a composite insulator, and relates to the technical field of electric power equipment. The composite insulator comprises a sheath (1), umbrella skirts (2), an ERC high-temperature reinforced type acid-resistant rod core (3), a metal fitting (4), an insulation ground wire clamp (5) and an insulation sheath (6). The sheath (1) and the umbrella skirts (2) are integrally formed by molds, the thicknesses of the sheath (1) and the umbrella skirts (2) are the same, the ERC high-temperature reinforced type acid-resistant rod core (3) is disposed in the sheath (1), the metal fitting (4) is provided with a partition groove, the thickness of the partition groove is consistent, and the metal fitting (4) is installed on the sheath (1) and is sealed by use of high-temperature vulcanizate in high pressure. The composite insulator has the advantages of small size, convenient maintenance, light weight, convenient installation, high mechanical strength, difficult fragmentation, excellent shock-proof performance, good stain resistance performance, short production period and high quality stability, thereby having a quite good market popularization value.
