Description
The product represented by this dataset is a surge arrester, namely an electrical apparatus 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., manufactured through processes such as core body manufacturing, insulation, assembly and testing. This dataset is formed by merging surge arresters of various materials; when the material information of the surge arrester is unclear, this data 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 the downstream is mainly applied to the overvoltage protection of power systems, new-energy power generation and rail transit equipment. As for the system boundary, the packaging of the product and its post-delivery transport, use, scrapping, recycling and final disposal, as well as infrastructure such as the manufacture of production equipment and plant construction, 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.
