Description
The product represented by this dataset is a composite insulator, namely an insulating and mechanical-support device with composite materials such as silicone rubber, a core rod and fittings as the main components, manufactured through processes such as pretreatment, assembly and crimping, preheating and drying, vacuum mixing, gel injection, demoulding, cooling, appearance trimming and inspection; it has the performance of withstanding voltage and mechanical stress, with an average single-piece weight of about 12.91 kg. The key upstream raw materials of this product are composite materials such as the core rod, fittings and silicone rubber, and the downstream is mainly applied to the insulation and mechanical fixing of high-voltage overhead transmission lines, power plants, substations and electrical equipment. As for the system boundary, infrastructure such as the manufacture of production equipment and plant construction is not included within the dataset boundary. In terms of data sources and data processing, the data inventory is formed by merging data from multiple sources, and energy such as electricity is calculated using China's average energy mix.
Activity Description
The system boundary covers the composite insulator from cradle to gate, starting with raw-material inputs and ending when the finished composite insulator leaves the factory. The main stages, in sequence, are pretreatment, assembly and crimping, preheating and drying, vacuum mixing, gel injection, demolding, cooling, surface finishing, and inspection.
Process Description
Composite insulators are insulation and mechanical support devices made of composite materials such as silicone rubber, core rods (such as epoxy glass fiber) and hardware as the main components. They are made through pre-treatment, assembly and crimping, gel injection, mold removal cooling and appearance modification. They have the ability to withstand high voltage and mechanical stress and are in the form of a shed and core rod combined structure. This product is installed between conductors of different potentials or between conductors and grounding components. It is widely used in the insulation and mechanical fixation of high-voltage overhead transmission lines, power plants, substations and electrical equipment.

Technology comment
The production of composite insulators mainly includes pretreatment, assembly and crimping, preheating and drying, vacuum stirring, gel injection, demolding, cooling, appearance finishing, and inspection. After pretreatment, the fittings and mandrels are placed into the mold, then assembled, crimped, preheated, and dried. Under vacuum conditions, they are stirred and gel is injected. After demolding, cooling, and appearance finishing, they are assembled into composite insulators.
