Imatra Electricity Substation / Virkkunen & Co Architects

该项目由芬兰东部Imatra的一座变电站和五座输电塔而构成，整个项目延伸至Vuoksi河的两个支流以及Imatrankoski的文化景观，在上世纪20年代，Imara水电站刚建成时，水流则用于发电，这个地标工业场地是芬兰主要电网的首个部分的起点，这个地区的历史意义则在于，项目的运营商希望能有一座特别的变电站设施。

Text description provided by the architects. The project is composed of an electricity substation building and five transmission towers and terminals in Imatra in Eastern Finland. The project extends over two tributaries of the river Vuoksi and the culturally significant landscape of Imatrankoski rapids. The rapids were harnessed for power generation in the 1920s when the Imatra hydropower plant was constructed. This landmark industrial site was also the starting point of the first part of the Finnish main power grid. The historical significance of the area was why our client, the main grid operator Fingrid Oyj, pursued an exceptional substation facility.







旧水电站建筑的特点是红砖立面，其门窗布局很有韵律，整体节奏也成为全新变电站立面和电力线条结构的主要特征，原有的空气绝缘开关设备于1929年完工，已无法继续使用，因此需要在新变电站中更换新设备。

The outstanding feature of the old hydropower plant buildings' red brick-clad facades is the rhythmic arrangement of window bays and doors. Rhythm also became the main feature of the new substation facades and powerline structures. The old air-insulated switchgear, completed in 1929, was coming to the end of its operational life cycle and had to be replaced with gas-insulated switchgear housed in a new substation building.







新的电力线结构取代了新变电站东西侧的原有构架塔，除了新的输电线的位置，原有的水电站建筑的规模和位置都成为了新变电站建筑布局的主要因素，变电站的下层设置在地下，呼应了原有建筑的高度，而新的输电结构的设计构成了建筑与自然之间的平衡，除了塔楼，其他部分都低于周边树木。

New powerline structures replaced old lattice-type towers to the east and west of the new substation. Besides the location of the new powerlines, the scale and coordinates of the old hydropower plant buildings were primary factors in the positioning and layout of the new substation building. The lower floor of the substation is set underground to match the height of the nearest section of the old power plant. The design of the new transmission structures also seeks balance with the built and natural landscape, with all but one tower being lower than surrounding trees.





新变电站有着混凝土框架和双层墙体，最外侧的立面由手工制作的砖石建造而成，这些砖石呈之字形，这种排布方式与新电力线塔楼的三角形钢材相同，双层立面的内层由现浇和预制混凝土墙体建造而成，而它们又由砖材格栅后方的条形创切割制成。

The new substation building has a concrete frame and double-skin facades. The outermost facade layer consists of hand-made long bricks laid in a zigzag profile, a motif which the building shares with the triangular steel profiles of the new powerline towers and terminals. The inner layer of the double facade consists of in-situ and prefabricated concrete walls cut by a continuous strip window set behind the brick lattice.





在建筑内部，主要工艺设备用房和大堂通过高侧窗接受自然采光，使用者通过高侧窗能够看到双立面的砖石格栅，建筑内部受到外部预制混凝土构件的结构、细部的限定，整个项目包含有三种传输结构，即一个垂直布置交叉臂的高塔、两个交叉臂水平布置的电缆塔，以及两个连接架空线路和地下电缆的终端。

Inside the building, the main process equipment room and the lobby receive natural light via the clerestory window strip through which the brick lattice of the double facade can be seen. The interior is defined by the structural logic, detailing, and materiality of the exposed, prefabricated concrete parts. The project features three types of transmission structures: a tall tower with vertically arranged cross-arms, two low pylons with a horizontal configuration of cross-arms, and two terminals that connect overhead lines with underground cables.



整个结构包含了重复布置的三角形钢材预制组件，Imatra变电站的各个部分分布在一个大区域之中，其中的主要设计挑战则是构成一个与环境相协调的连贯整体，建筑师将其中的各个部分分离开，然后以全新的抽象形式再重新组装，构成的全新设计语言给新项目带来了新特征，并且和环境很好地结合在一起。

The structures consist of prefabricated sections of triangular steel profiles in repetitive arrangements. The various parts of Imatra Electricity Substation are spread over a large area, and the main design challenge was to form a coherent whole that fits in the setting. The design breaks apart aspects of the built context and reassembles them in a new abstracted form. The derived design language gives a unified identity to the new project and places it in the context.
