Description
The product represented by this dataset is a glass insulator, namely an insulating and mechanical-support device with a toughened glass piece as the main insulator, with a single-piece weight of about 10 kg, mainly composed of a glass piece, an iron cap and cement mortar (cement, yellow sand, etc.), manufactured through processes such as cement mortar preparation, assembly, rinsing, curing and testing. The key upstream raw materials of this product are cement, yellow sand and the glass piece, iron cap, etc., 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 for the glass insulator is set from cradle to gate, with the starting point being the input of raw materials and the end point being the dispatch of the finished glass insulator from the plant. The primary stages, in sequential order, comprise cement mortar preparation (including cement and sand), assembly (comprising glass shells and iron caps), rinsing, curing, and testing.
Process Description
Insulators are devices installed between conductors of different potentials or between conductors and grounding components and can withstand voltage and mechanical stress. They are mainly divided into porcelain insulators, glass insulators and composite insulators. Glass insulators refer to insulators with tempered glass parts as the main insulator. They are mainly composed of glass parts, iron caps and cement mortar (cement, yellow sand, etc.). They have the ability to withstand high voltage and mechanical stress. They are in the form of a combination structure of solid or hollow glass parts and metal accessories. They are 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 glass insulators mainly includes cement mortar preparation, assembly, washing, curing and testing. After mixing cement, silica sand, etc. to make mortar, it is assembled with glass parts, iron caps, etc., and is rinsed with water to remove surface dirt. After passing the curing and testing, the finished glass insulator is made.
