In order to maintain the reliability, safety, and sustainability of power transmission, defect detection of insulators has become an important task in power inspection. Therefore, this article proposes an improved model P-YOLOv8 for insulator defect detection. By integrating the Slim-neck module and the Convolutional Block Attention Module (CBAM) attention mechanism module, the model’s feature extraction ability for small target objects has been significantly improved, thus better adapting to the characteristics of insulator defect datasets. The introduction of the CBAM attention mechanism module enables neural networks to focus more on capturing insulator defect information; The Slim-neck module is a neural network structure used for object detection. The modules in the Slim-neck module first use lightweight convolution GSConv, which enhances the recognition of key features, and uses depth wise separable convolution to reduce the computational cost of the model. Through comparative analysis of YOLOv5 and YOLOv8 models, we have decided to adopt the improved P-YOLOv8 model as the preferred model for predicting insulator defects. P-YOLOv8 achieved accuracy, recall, and mAP kp of 97.2%, 98.4%, and 99.3%, respectively, significantly improving compared to YOLOv5. In addition, P-YOLOv8 performs excellently in light intensity environments, with accuracy, recall, and mAP kp of 92.17%, 90.2%, and 97.6%, respectively, which is an improvement compared to YOLOv8. These data fully demonstrate that the improved P-YOLOv8 model not only maintains a high level of network model accuracy, but also has strong robustness to complex environmental factors such as light lines. Therefore, it can effectively cope with the task of predicting insulator defects in complex environments, providing strong technical support for the safety monitoring of %K 绝缘子， %K 改进YOLOv8， %K 注意力机制， %K 目标检测
