缠绕角度对复合绝缘子用玻纤缠绕管关键性能的影响

Influence of Winding Angle on Key Properties of Fiberglass Wound Tubes for Composite Insulators

本文对缠绕角度为40°、45°、50°、55°、60°以及65°的复合绝缘子用玻纤缠绕管进行了关键机械和电气性能研究。结果表明,随着缠绕角度的增加,材料的轴向拉伸和垂直层向弯曲强度逐渐降低,轴向压缩强度逐渐增大,平行、垂直层向击穿强度和介电常数基本持平。在实际工程应用中,综合考虑缠绕角度控制在50°~60°较为合适,也可采用多角度复合缠绕。

The key mechanical and electrical properties of fiberglass wound tubes for composite insulators with wind⁃ing angles of 40°,45°,50°,55°,60°and 65°were compared in this paper.the results show that with the increase of winding angle,the axial tensile,vertical layer to the bending strength decreases and the axial compression strength in⁃creases gradually;parallel,vertical layer to the breakdown strength and dielectric constant were little changed.In practical engineering applications,it is more appropriate to control the winding angle between 50°and 60°compre⁃hensively,and multi-angle composite winding can also be adopted.
