Description

Technical Field

[0001] The utility model relates to the technical field of insulated wires, in particular to a low-loss multi-strand insulated wire. Background Technique

[0002] Insulated wires are widely used, such as in television stations, hospitals, cinemas, commercial buildings, subways, tunnels, railways, airports, stations, large public sports venues, large supermarkets, high-rise buildings, military facilities, coal mines, chemical industries, medicine, steel, metallurgy, ships, civil use, etc.

[0003] The multi-strand insulated wire is a kind of insulated wire, which is composed of multiple copper wires stranded together, having high electrical conductivity and can withstand a larger current. However, as Figure 1 shown, the multiple copper wires inside the multi-strand wire are all circular in shape. After the multiple copper wires are stranded, there will be gaps in the middle, resulting in a relatively loose internal structure. At the same time, the cross-sectional area of the multi-strand wire is also relatively larger. Content of the Utility Model
