With the inception of high voltage (HV), requisites on the insulating permanence of HV equipment is becoming increasingly crucial. Mineral/synthetic oil liquid insulation-together with solid insulation materials (paper, pressboard)-is the fundamental insulation constituent in HV apparatuses; their insulation attributes perform a substantial part in a reliable and steady performance. Meanwhile, implications on the environment, scarcity of petroleum oil supplies and discarding complications with waste oil have stimulated investigators to steer their attention towards sustainable, renewable, biodegradable and environmentally friendly insulating substances. The contemporary insulating constituent's evolution is driven by numerous dynamics-in particular, environmental obligations and other security and economic issues. Consequently, HV equipment manufacturers must address novel specifications concerning to these new standards. Renewable, sustainable and environmentally friendly insulating materials are continuously substituting conventional insulating items in the market place. These are favorable to traditional insulating materials, due to their superior functionality. The also offer explicit security and eco-friendly advantages. This article discusses cutting-edge technology of environmentally friendly insulating materials, including their fabrication, processing and characterization. The new renewable, insulating systems used in HV equipment are submitted and their fundamental gains stated in comparison with conventional insulating materials. Several experimental efforts carried out in various parts of the world are presented, offering an outline of the existing research conducted on renewable insulating systems. The significance of this article lies in summarizing prior investigations, classifying research essence, inducements and predicting forthcoming research trends. Furthermore, opportunities and constraints being experienced in the field of exploration are evidently reported. Last but not least, imminent research proposals and applications are recommended.
随着高压（HV）的出现，对 HV 设备绝缘耐久性的要求变得越来越重要。矿物/合成油液体绝缘-与固体绝缘材料（纸、层压板）一起-是 HV 设备中的基本绝缘组成部分；它们的绝缘性能在可靠和稳定的性能中起着重要作用。同时，对环境的影响、石油供应的稀缺以及废油处理的复杂性，促使研究人员将注意力转向可持续、可再生、可生物降解和环保的绝缘物质。当代绝缘材料的发展受到多种因素的驱动-特别是环境义务以及其他安全和经济问题。因此，HV 设备制造商必须满足这些新标准的新规范。可再生、可持续和环保的绝缘材料不断取代市场上的传统绝缘材料。由于其卓越的功能，它们对传统绝缘材料有利。它们还提供明确的安全和环保优势。本文讨论了环保绝缘材料的最新技术，包括它们的制造、加工和特性。提交了用于 HV 设备的新型可再生绝缘系统，并与传统绝缘材料相比说明了它们的基本优势。介绍了世界各地进行的几项实验研究，概述了在可再生绝缘系统方面进行的现有研究。本文的意义在于总结先前的研究，分类研究的本质、动机并预测未来的研究趋势。此外，还明显报告了探索领域中遇到的机会和限制。最后但并非最不重要的是，建议了即将进行的研究建议和应用。
