Description
This dataset is a market dataset, representing the consumption market of the region; the dataset includes the transport of the product from the gate to the consumer end, and the transport service is calculated according to the transport situation of this product in this region. The product represented by this dataset is a composite insulator, which is an insulation and mechanical support device with composite materials such as silicone rubber, a core rod and fittings as the main components, made through processes such as pretreatment, assembly and crimping, preheating and drying, vacuum stirring, 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 downstream it is mainly applied in the insulation and mechanical fixing of high-voltage overhead transmission lines, power plants, substations and electrical equipment. In terms of system boundary, infrastructure such as the manufacture of production equipment and the construction of plant buildings 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 electricity and other energy are calculated using the Chinese average energy structure.
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.
