Embodiment Construction

[0019] Such as figure 1 with figure 2 As shown, a pre-twisted aviation warning ball, including a sphere 1, is provided with a through-hole 2 for the cable 4 to pass through the sphere 1 on the sphere 1, and in order to prevent the cable from vibrating from damaging the sphere, a The sheath 3 is provided, and a rubber pad 8 is arranged in the sheath. Four groups of pre-twisted wire through-holes 5 passing through the sphere are arranged at the through-hole 2 on the sphere 1 along the periphery of the through-hole. In order to avoid damage to the sphere, an aluminum casing 7 is also arranged in the pre-twisted wire through hole 5 , and the pre-twisted wire protection bar 6 is set through the aluminum casing 7 . The above-mentioned pre-twisted wire protection bar 6 is made of 2-3 aluminum-clad steel monofilaments with a diameter of 3.5 mm.

Abstract

The invention discloses a pre-twisted aviation alerting ball. The pre-twisted aviation alerting ball comprises a ball body, a through hole is formed in the ball body, a cable penetrates through the ball body through the through hole, and a protection sleeve is arranged inside the through hole. The pre-twisted aviation alerting ball is characterized in that the ball body is fixed to the cable through a pre-twisted wire amour rod. The elasticity modulus is large, the pre-twisted aviation alerting ball can provide sufficient holding force and is not prone to deforming after installing, and the ball body can be well fixed.

Description

technical field [0001] The invention relates to an aviation warning ball, in particular to a pre-twisted aviation warning ball. Background technique [0002] Aviation warning balls are mostly used in ultra-high voltage (500,000 kV) transmission lines, cross-river transmission lines, etc. At present, most of the most common aviation warning balls are bolt type aviation warning balls, the diameter of which is ф=600mm, the color of the ball is all orange, the material of the ball is engineering reinforced plastic, and it is connected by stainless steel bolts. For aluminum parts, a protective wire needs to be wrapped around the outer layer of the cable for protection during installation. Because of the high vibration frequency of the cable installed at high altitude, the bolt-type aviation warning ball is subjected to long-term vibration, and the cable is prone to stress damage at the exit of the fastening clamp end, and the bolt-type clamp has the hidden danger of loosening or...
