The product is jointly produced by our company and ABB. It is a kind of new air-insulated switchgear used in three-phase A.C. 50Hz, 110kV power system as power receiving, distribution, control, protection and measurement in these fields such as power plant, substation, industrial and mining enterprise, airport, hospital, school, oil and petrol-chemical enterprises, metallurgy, commercial area and residential area, port and other fields .
Service conditions : Altitude: no higher than 3000m, ambient temperature: -40℃～+55℃，max. wind speed: no more than36m/s，Ice thickness: no more than 10mm, pollution level: no more than Ⅳ, earthquake intensity: doesn’t exceed 8°, indoor and outdoor installation.
(1)Jointly produced with ABB ADDA, international brand, guaranteed quality.
(2)Perfect combination of creativity, reliability, flexibility and economy
(3)Modular design: A large number of functional components such as the circuit breaker, current transformer, disconnector, earthing switch and even lightning arrester are compacted in a functional equipment.
(4) Due to the draw-out structure adopted, power outage time is shortened.
(5) Horizontal arrangement of the circuit breaker lowers the equipment height, so the equipment can be used in both indoors and outdoors. Convenient for assembly of 110KV mobile substation
(6) Modular design greatly reduces transport volume, and horizontal placement of the circuit breaker lowers the transport height. Fast installation shortens the installation period. The most important is that the compacted structure greatly reduces the land occupation of the equipment and grounding grid area, this can save a lot of expenses in land acquisition, civil engineering, installation and commissioning etc, so as to reduce the overall cost of the distribution room.
