特高压支柱复合绝缘子用芯棒及其制造方法
摘要：
本发明涉及电力行业输变电用的一种特高压支柱复合绝缘子用芯棒及其制造方法，由棒芯、缠绕管组成，缠绕管设置在棒芯的外围，缠绕管为浸渍环氧树脂胶的玻璃纤维纱缠绕固化的管体，其特征在于：所述的棒芯为表面具有阻尼槽的芯体；所述的缠绕管由铺层I、铺层II、铺层III组成，铺层I、铺层II、铺层III分别经浸渍环氧树脂胶的玻璃纤维纱缠绕固化而成；由于采用拉挤棒为内芯，并在棒芯表面加工有阻尼槽，从而使棒芯与缠绕管连接更可靠；由于缠绕管由多层铺层组成，并通过分层缠绕、固化形成大直径芯棒，从而使缠绕管性能更高，可适用于特高压状况，大大提高了支柱复合绝缘子的抗风和抗弯曲能力。
摘要（英）：

The invention relates to a core rod of an ultra-high-voltage post composite insulator used for power transmission and transformation in the power industry and a manufacturing method thereof. The core rod consists of a rod core and a winding tube, wherein the winding tube is arranged on the periphery of the rod core and is a tube made by winding and curing a glass fiber yarn dipped with epoxy resin glue. The core rod is characterized in that the rod core is a core body with a damping slot on the surface thereof, and the winding tube consists of a layer I, a layer II and a layer III, and the three layers are respectively formed by winding and curing a glass fiber yarn dipped with epoxy resin glue. Since the pultrusion rod is used as an inner core, and the damping slot is processed on the surface of the rod core, the connection between the rod core and the winding tube is more reliable; and since the winding tube consists of multiple layers and forms a large-diameter core rod through laminated winding and curing, the invention improves the performance of the winding tube, is applicable to the ultra-high-voltage condition and greatly improves the wind resistance and bending resistance of the post composite insulator.
