Polypropylene‐based nanocomposites for HVDC cable insulation

Abstract

Cross‐linked polyethylene (XLPE) is commonly used as an insulation material in power cables. Due to the recent advancements in the field of high voltage power transmission and distribution, there is a need for novel cable insulation materials that have high performance, recyclability and high working temperature as alternatives for the conventional XPLE‐based insulation materials. Polypropylene (PP) shows excellent properties and has drawn considerable attention as a potential high voltage direct current (HVDC) insulation material. Therefore, the development of PP‐based HVDC cable insulation with improved electrical, thermal and mechanical properties is important in discovering a potentially recyclable cable insulation material. Due to the remarkable development in the field of nanodielectrics, nanotechnology can be a promising solution for enhancing the overall dielectric properties of PP‐based insulation materials. This review presents the important aspects of PP‐based nanocomposites for HVDC cable insulation with a special focus on understanding the effects of various parameters of nanofillers on the dielectric properties of PP‐based HVDC cable insulation. Based on the gathered information, future perspectives for improving the dielectric properties of PP‐based nanocomposites for HVDC cable are provided.

Ferrite-Supported Nanocomposite Polymers for Emerging Organic and Inorganic Pollutants Removal from Wastewater: A Review

“…The top-down technique of directly combining nanofillers with polymer matrixes, such as melt mixing and solution mixing, is supported by the dissolution of crystallized fillers during the blending process , However, the high temperatures used to melt the polymer may have an effect on the surface functionalization of the filler . The melt-blending method with ultrasonic treatment to strengthen the distributions of GNPs was used to successfully prepare bionanocomposite PLA/LNR/PANi/GNPs with various nanofiller loadings .…”

Eco‐friendly polypropylene power cable insulation: Present status and perspective

“…In the following 20 years, the development of PP‐based cable insulating materials has attracted wide attention in the world. Nano‐doping, chemical grafting, in‐suit copolymerisation, heat treatment, nucleating agent, voltage stabiliser, elastomer blending and other modification routes have been developed [1, 3, 7, 8]. Remarkable enhancements have been achieved for the electrical and mechanical properties of PP.…”

“…The limitations of XLPE insulation are gradually recognised. Firstly, XLPE is a thermosetting material, which makes the recycling of waste cables very difficult [1,2]. Conventional incineration or burial treatment will lead to serious environmental pollution.…”
