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 porcelain insulator, which is an insulation and mechanical support device made from electrotechnical ceramics (aluminosilicate porcelain, mainly composed of kaolin, feldspar, quartz, etc.) as raw material through forming, glazing, firing and assembly; it has the performance of withstanding voltage and mechanical stress, with an average single-piece weight of about 9.5 kg, in the form of solid or hollow porcelain pieces. The key upstream raw materials of this product are clay (kaolin, feldspar, quartz, etc.) and glaze, made through processes such as forming, glazing, firing and assembly; 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, the dataset contains the raw and auxiliary materials, energy (electricity, etc., based on the Chinese average energy structure) and waste of the main processes such as forming, glazing, firing and assembly, and does not include infrastructure such as the manufacture of production equipment and the construction of plant buildings, i.e. equipment manufacture and plant building construction, etc., are explicitly excluded from 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 is the cradle-to-gate of porcelain insulators, the starting point is the input of raw materials, and the end point is the delivery of finished porcelain insulators from the factory. The main stages include raw material preparation and clay processing, molding (pressing or extrusion, etc.), glazing, drying, high-temperature firing in the kiln, and assembly and inspection. The above stages together constitute the system boundaries and process steps covered by the data set.
Process Description
Porcelain insulators are insulation and mechanical support devices made of electrical ceramics (aluminosilicate porcelain, mainly composed of kaolin, feldspar, quartz, etc.) through shaping, glazing, firing and assembly. They have the ability to withstand high voltage and mechanical stress and are in the form of solid or hollow porcelain parts. 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. It is a key insulation component in power grids and electrical equipment.

Technology comment
The production of porcelain insulators mainly includes forming, glazing, firing, and assembly. The prepared ceramic body material, including kaolin, feldspar, and quartz, is pugged and aged and then pressed or extruded to form green bodies. A glaze is applied to provide an insulating and protective layer. After drying, the green bodies are fired in a kiln at approximately 1,200-1,400°C, depending on the formulation and kiln type, causing the body to vitrify and the glaze to become glassy. The fired porcelain components are inspected and assembled with metal fittings by cementing or mechanical means to produce finished porcelain insulators.
