35kV-1100kV Ultra high voltage pillar composite insulator

The composite insulator for power system is composed of three main components: core body (FRP), silicone rubber umbrella sleeve (HTV), and end flange (precision cast steel, welded steel, stainless steel). The two end flanges are assembled with the core body by crimping. This product has excellent anti fouling flashover performance, anti brittle fracture, excellent insulation performance, light weight, easy installation and transportation, safety and reliability, and other advantages. Pillar composite insulators are used in electrical equipment such as substations and converter stations with AC voltage ranging from 40.5kV to 1100kV and DC voltage ranging from ± 100kV to ± 800kV. The main application products include reactor supports, high-voltage isolation switch insulation pillars, busbar supports, and insulation supports for other high-voltage equipment.

Product Features
a) Core: Using epoxy resin glass fiber pull rods as internal insulation support, it has excellent seismic performance and can prevent brittle fracture;
b) Silicone rubber umbrella cover: injection molded as a whole, optimized umbrella design, improved crawling distance effectiveness and product pollution flashover voltage;
c) End flange: The flange is assembled using crimping technology, which ensures stable and reliable mechanical performance and high production efficiency;
d) The overall weight of the product is lighter than that of porcelain insulators, making it easier to install, with a short production cycle and high quality stability.
