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 silicone-rubber-housed metal oxide surge arrester, which is a surge arrester whose valve plate uses zinc oxide as the main material, doped with a small amount of other metal oxide additives and made by high-temperature roasting, and whose insulating material is silicone rubber, with a single-unit weight of about 2.39 kg, mainly composed of resistor plates (core body), silicone rubber, silane coupling agent and metal fittings such as screws, end caps, nuts and flat spring washers, made through processes such as core body drying, rubber coating, forming, cooling, trimming, assembly and testing. The key upstream raw materials of this product are resistor plates, silicone rubber, silane coupling agent, industrial alcohol and screws, end caps, nuts and flat spring washers, 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 formed by merging data from multiple sources.
Activity Description
The system boundary covers the silicone-rubber-housed metal-oxide surge arrester from cradle to gate, starting with raw-material inputs and ending when the finished arrester leaves the factory. The main stages, in sequence, are core drying (resistor elements), encapsulation with silicone rubber, a silane coupling agent, industrial alcohol, and other materials, molding, cooling, trimming, assembly with screws, end caps, nuts, flat spring washers, and other fittings, 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. Surge arresters can be broadly classified as metal-oxide, valve-type, and expulsion-type arresters; by housing material, they may use silicone-rubber, porcelain, or composite housings. A silicone-rubber-housed metal-oxide surge arrester uses valve elements made primarily of zinc oxide with small amounts of other metal-oxide additives and sintered at high temperature, together with a silicone-rubber insulating housing. It mainly consists of resistor elements (the core), a silicone-rubber housing, and metal fittings such as screws, end caps, nuts, and flat spring washers. It limits overvoltage and follow current, is supplied as a pedestal-mounted or cubicle-mounted electrical device, and is widely used for overvoltage protection in power systems, renewable-energy generation, and rail transit equipment.

Technology comment
The production of silicone rubber jacketed metal oxide arresters mainly includes processes such as core drying, silicone rubber wrapping, molding, cooling, trimming, assembly, and testing. After the outsourced core is dried, its surface is coated with a coupling agent, then wrapped with silicone rubber, molded, naturally cooled, and trimmed. Subsequently, metal accessories such as screws, end caps, nuts, and flat spring washers are assembled. After passing the electrical performance test, the finished silicone rubber coated metal oxide arrester is produced.
