The invention provides an insulating arm, engineering mechanical equipment with the insulating arm and a preparation method of the insulating arm. The insulating arm (1) is made of a hollow tubular insulating composite material formed by fibers impregnated with resin, and is provided with at least one winding unit. The winding unit has a winding unit structure of [alpha] n/[gamma] m/[beta] p, [alpha] n forms a first fiber portion (11) of the insulating arm, [gamma] m forms a second fiber portion (12) of the insulating arm, [beta] p forms a third fiber portion (13) of the insulating arm, [alpha], [gamma], and [beta] are angles of the fibers with respect to an axial direction of the insulating arm, [alpha] is in a range of 0 +/-2 DEG, [gamma] is about +/-45 DEG, and [beta] is in a range of 0 +/-2 DEG. The fiber is wound around the metal core mold, beta is within the range of 90 +/-2 degrees, n is the number of winding layers of the fiber with the angle alpha relative to the axial direction of the metal core mold, m is the number of winding layers of the fiber with the angle gamma relative to the axial direction of the metal core mold, m is an even number, and p is the number of winding layers of the fiber with the angle beta relative to the axial direction of the metal core mold.

    本公开提供一种绝缘臂、具备该绝缘臂的工程机械设备及该绝缘臂的制备方法。绝缘臂(1)由浸渍了树脂的纤维形成中空管状绝缘复合材料,具有至少一个铺缠单元。所述铺缠单元具有αn/γm/βp的铺缠单元结构,αn形成所述绝缘臂的第一纤维部(11),γm形成所述绝缘臂的第二纤维部(12),βp形成所述绝缘臂的第三纤维部(13),α、γ、β为所述纤维相对于所述绝缘臂的轴向的角度,α在0±2°范围内,γ为±45°左右,β在90±2°的范围内,n为所述纤维相对于所述金属芯模的轴向的角度为α的缠绕层数,m为所述纤维相对于所述金属芯模的轴向的角度为γ的缠绕层数,且m为偶数,p为所述纤维相对于所述金属芯模的轴向的角度为β的缠绕层数。
