Abstract

The invention discloses a highly hydrophobic outdoor strain insulator, which comprises a core rod, umbrella-shaped parts arranged outside the core rod, coatings that coat the surfaces of the umbrella-shaped parts, and end assemblies at the two ends of the core rod. The basic body of the core rod is made from epoxy resin, and the main reinforcing body of the core rod is a mixed body of directional aramid fiber material and alkali-free glass fiber that are arranged in a certain manner. The umbrella-shaped parts are made from outdoor epoxy resin high in weatherability. The highly hydrophobic outdoor strain insulator exhibits high tensile strength, high hydrophobicity and high weatherability, can be accurately controlled in molding dimension, is high in production efficiency, and is substantially improved in overall rigidness compared with silicone rubber insulators. The core rod can be better combined with the umbrella-shaped parts. In a word, the outdoor strain insulator exhibits higher tensile strength, and is high in hydrophobicity and weatherability.

Description

【Technical field】

[0001] The invention relates to a high-voltage power transmission and transformation insulator, in particular to a highly hydrophobic outdoor tension insulator. 【Background technique】

[0002] Traditional insulators made of ceramics and glass are not only heavy, but also easy to damage; Silicone rubber insulators have poor rigidity and are easily damaged by birds in areas where bird damage occurs frequently. Moreover, due to the low hardness and low strength of the silicone rubber material, it is easy to cause damage during the assembly process, especially in the high-voltage level, due to the long length of the insulator, it is easy to cause damage to the partial umbrella, resulting in product scrapping. In plateau areas, silicone rubber insulators also need to prevent birds from pecking during line assembly. Compared with silicone rubber insulators, epoxy resin insulators have the characteristics of high strength, good rigidity, and anti-bird pecking. Th...
