“…Considering the influence of material, formulation, process, manufacturing level, the performance between RTV, LSR and HTV is shown in Table I. It is shown that HTV has the highest molecular weight, the most stable bond energy, and the best curing conditions of high temperature glue [4] . That means the heat resistance, oxygen ageing, weather resistance, UV resistance, electrical leakage resistance and corrosion resistance are the most excellent in silicone rubber insulation.…”

Abstract-The ageing properties, detection technology and assessment method were researched in the paper. First, the influence on the silicone rubber materials of transmission and distribution equipment was analyzed. Second, based on the mutitechnology fusion of macroscopic and microscopic detection method, the mechanical performance, electrical performance, hydrophobicity and microscopic structure of 110kV and above silicone rubber materials was tested. Then, the strong characteristics reflecting the ageing properties were extracted and graded. Finally, the linear weighting method was used for the assessment of ageing state, and the maintenance strategy was mapped out. The assessment results can well reflect the ageing state of the silicone rubber materials, and also are available and helpful for the equipment management departments.

“…However, as the operating life increases, the aging problem becomes more and more serious. Due to long-term exposure to the harsh environment, external insulation of composite insulators can suffer from multiple stresses such as electrical discharge, temperature and mechanical stress et al [9][10][11][12][13] In hot and humid areas all over the world, they are also accompanied by the problem of hydrothermal aging. Therefore, it is of great signicance to carry out multiple stress aging research on external insulation materials of composite insulators for mastering the aging rule and evaluating the insulation state.…”

“…Since the 1970s, silicone rubber (SiR) has been used for outdoor insulation [1]. Due to its light weight, unique hydrophobicity, better pollution/contamination performance, easy installation, and excellent insulation properties (resistivity of >10 12 Ω) , SiR composite insulators are broadly employed in high-voltage (HV) transmission and distribution [2]. However, these polymeric materials are affected by various types of environmental and electrical stresses, which limit their use as HV insulants [3,4].…”

In recent years, silicone rubber-based composites have been widely investigated for outdoor applications due to their promising insulating properties. However, mechanical, thermal, and tracking properties of pure silicone rubber are very poor, which restrains its application for long-term performance. In this research work, the influence of microsized alumina trihydrate (ATH) and micro/nanosized silica (SiO 2) fillers on mechanical, thermal, and electrical properties of room temperature vulcanized silicone rubber (RTV-SiR) has been studied. SiR-blends with varying amounts of ATH and SiO 2 particles were prepared by blending in a two-roll mixing mill, compression molding, and postcuring processes in sequence. In order to evaluate relative tracking and erosion resistance of SiR-blends, an inclined plane test (IPT) was conducted in accordance with the ASTM D2303 standard procedure. Surface temperature distribution was recorded using a Fluke-Ti25 infrared camera during IPT experiments. Thermogravimetric analysis was carried out to analyze the thermal stability of ATH and silica-filled silicone rubber samples. Tensile strength, percent elongation at break, hardness, erosion, tracking resistance, and thermal properties were also investigated and discussed. Results showed that the mechanical, thermal, tracking, and erosion performances of SiR-blends are improved by the incorporation of ATH and silica particles, which is governed by filler type, size, and wt.% in the polymer matrix.
