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 surge arrester, which is an electrical appliance used to protect power equipment from the hazards of high transient overvoltages and to limit the duration and amplitude of the follow current, with a single-unit weight of about 2.26 kg, mainly composed of resistor plates, insulating materials and parts, etc., made through processes such as core body manufacture, insulation, assembly and testing. This dataset is formed by merging surge arresters of various materials; when the material information of the surge arrester is unknown, this entry can be selected as a substitute. The key upstream raw materials of this product are resistor plates, insulating materials and assembly parts, etc., and downstream it is mainly applied in the overvoltage protection of power systems, new energy power generation and rail transit equipment. In terms of system boundary, the packaging of the product and the transport, use, scrapping, recycling and final disposal after leaving the factory, as well as infrastructure such as the manufacture of production equipment and the construction of plant buildings, are not included within the dataset boundary. In terms of data sources and data processing, the data inventory is taken from the actual situation of production enterprises.
Activity Description
The system boundary is the cradle-to-gate of the arrester, the starting point is the input of raw materials, and the end point is the delivery of the finished arrester from the factory. The main stages include core manufacturing (resistors, etc.), insulation (insulating materials, etc.), assembly (parts, etc.) and testing.
Process Description
A surge arrester is an electrical device used to protect electrical equipment against high transient overvoltages and to limit the duration and magnitude of follow current. The main types include metal-oxide, valve-type, and expulsion-type surge arresters; by housing material, they may use silicone-rubber, porcelain, or composite housings. A surge arrester mainly consists of resistor elements, insulating materials, and a housing. It limits overvoltage and follow current and is supplied as a pedestal-mounted or cubicle-mounted electrical device. It is widely used for overvoltage protection in power systems, renewable-energy generation, and rail transit equipment.

Technology comment
Arrester production mainly includes core manufacturing, insulation, assembly, and testing processes. In core manufacturing, resistor discs and other core components are processed and assembled, then insulated with insulating materials. Subsequently, the parts are assembled into a complete unit, and after passing the test, the finished arrester is produced.
