According to the introduction of Nongqing Leather, the information exchange between secondary equipment in Ganhezi Substation has been networked. The substation as a whole adopts a three-layer and two-network structure. Each equipment in the station adopts optical fiber and network cable communication, which not only greatly reduces control cables, but also realizes high standardization of information in the station and high integration and sharing. Among them, the 35 kV switch cabinet adopts inflatable cabinet, saving floor space and realizing low carbon environmental protection requirements. He pointed to the 110KV secondary equipment compartment and said:

China's offshore wind power has started in batches in recent years. Domestic power transmission and transformation equipment enterprises are fully equipped with offshore wind power booster station AC and DC transformers, tower dedicated transformers, IGBT, GIS, switch cabinets and other power transmission and transformation equipment research and development and manufacturing capabilities. However, affected by the performance, it is difficult to win the bid in the market competition, which makes it difficult for the localization and market-scale application of offshore wind power transmission and transformation equipment, which is not conducive to national energy security. In addition, in the offshore and onshore booster stations of 220 kV and below with relatively mature technology and market, the market scale application of related complete sets of power transmission and transformation equipment is still insufficient, the market share of domestic enterprises of switchgear and other equipment is very low, and the R & D design of integrated supply is not enough.
