Product descriptions from the supplier
Product Introduction
Post composite insulators are composed of core rods, end fittings, and silicone rubber shed sheaths. They are mainly used for insulation and mechanical fixation of busbars and electrical equipment in power plants and substations. Their categories include post composite insulators for busbars, post composite insulators for reactors, composite insulators for disconnectors, and other high-voltage electrical equipment.
The connection between epoxy resin glass fiber rods and fittings adopts a crimping process, with crimping parameters digitally controlled, ensuring consistent and reliable mechanical performance. The sheds and sheaths are made of silicone rubber, and the shed shape adopts an aerodynamic structural design, with excellent pollution flashover resistance. The sealing of sheds, sheaths, and end fittings adopts the integral injection molding process of high-temperature vulcanized silicone rubber, with reliable interface and sealing performance.
Hollow composite insulators consist of aluminum alloy flanges, glass fiber-reinforced resin sleeves, and silicone rubber shed sheaths. They are commonly used in high-voltage electrical equipment such as GIS combined switches, transformers, mutual inductors, capacitors, arresters, cable accessories, and wall bushings.
The connection between glass fiber-reinforced resin sleeves and aluminum alloy flanges adopts the process of placing sealing rings, then pressurizing and bonding with epoxy glue, with parameters digitally controlled, ensuring consistent and reliable mechanical performance. The sheds and sheaths are made of silicone rubber, and the shed shape adopts an aerodynamic structural design, with excellent pollution flashover resistance. The sheds, sheaths, and end fittings adopt the integral injection molding process of high-temperature vulcanized silicone rubber, and the sealing of end fittings adopts the combined sealing molding process of high-temperature and room-temperature vulcanized silicone rubber, with reliable interface and sealing performance.

Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?Why Do Substations Use Stones, Gravel, Pebbles, and Crushed Rock?In substations, equipment such as power and distribution transformers, transmission lines, voltage transformers, current transformers, and disconnect switches all require grounding. Beyond grounding, we will now explore in depth why gravel and crushed stone are commonly used in substations. Though they appear ordinary, these stones play a critical safety and functional role.In substation grounding design—especially when multiple gr01/29/2026 -
Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
