Home / High-voltage busbar type ais
There are several common configurations, each with its own advantages and limitations: 1️⃣ Single Busbar Simple and low-cost, but a fault on the bus will trip the entire station. UniGear ZS1 is available in single busbar, double busbar, or double-level configurations, certified for marine and seismic applications, and fully compliant with IEC, GB/DL, CSA, and GOST standards. Hitachi Energy offers a wide range of air-insulated switchgear (AIS) portfolio up to 1100 KV used in all types of climates and applications. Design of busbars and connections in air insulated substation This chapter focusses on the design implications of connecting or rigid, single or bundled conductors to HV equipment with connectors/clamps, either bolted, welded or compressed.
