Problems solved by technology

[0003] At present, the main fixing method of the high-voltage pin insulators used in 10KV overhead distribution lines is the wire binding method. The wire binding method is not only complicated, but also has low installation efficiency. There are also some problems in the structure: aluminum stranded wire The binding material of the steel-cored aluminum stranded wire is the same as that of the wire. The wire is affected by weather conditions such as wind, ice, and low tempera

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1~3 As shown, a high-voltage pin insulator with its own fixed wire fittings includes a porcelain body 2 and fixed wire fittings. The fixed wire fittings are two threaded zinc sleeves 3 arranged on the upper part of the porcelain body 2. The thread The zinc sleeve 3 is provided with a wire pressing plate 4, and the wire pressing plate 4 is locked by a stainless steel bolt 5. A steel foot 1 is provided at the lower part of the porcelain body 2, and one end of the steel foot 1 is inserted into the interior of the porcelain body 2, and the other end is inserted into the porcelain body 2. Installed on the cross arm of the utility pole.

[0023] In this embodiment, in order to make the threaded zinc sleeve 3, the steel foot 1 and the porcelain body 2 form a system, so that it has the functions of support, insulation and fixing...

Abstract

The invention relates to a high-pressure pin insulator with a fixed wire fitting. The high-pressure pin insulator comprises a porcelain insulator body and the fixed wire fitting. The fixed wire fitting is composed of two threaded zinc sleeves arranged on the upper portion of the porcelain insulator body, and a wire pressure plate is arranged on the threaded zinc sleeves and is locked through stainless steel bolts. A steel pin is arranged on the lower portion of the porcelain insulator body, one end of the steel pin is inserted into the porcelain insulator body, and the other end of the steel pin is arranged on a cross arm of a telegraph pole.

Description

technical field [0001] The invention relates to power distribution equipment, in particular to a high-voltage pin insulator with a fixed wire fitting. Background technique [0002] With the sustained and rapid development of the national economy, my country's electric power industry presents a trend of rapid development. Facing the huge market space for power demand and power supply construction, my country's power grid is faced with the arduous task of continuously increasing transmission capacity and safely and reliably transporting large-scale power from power plants to end users. The short-term and long-term grand goals of the national large power grid construction have brought rare development opportunities to the production of my country's ceramic insulator industry, and at the same time put forward higher requirements for the performance and quality of ceramic insulators. [0003] At present, the main fixing method of the high-voltage pin insulators used in 10KV over...
