This special screen is completely made of stainless\u00a0steel and does not need maintenance or cleaning. Only clear water can pass the\u00a0special designed gaps between the rack bars thus protecting the\u00a0 turbine runner\u00a0from extended wear and tear especially at high head installations.<\/p>\n<p style=\"text-align: justify;\">A hydraulically operated fish-beam flap gate of stainless steel was installed for\u00a0water intake level control and for flood relief. The flap gate is actuated by\u00a0 one\u00a0single hydraulic cylinder on the right side of the flap and it is equipped with a\u00a0heated slide wall.<\/p>\n<p style=\"text-align: justify;\">Last but not least a fully automatic pipe break protection device was installed\u00a0for safety reasons. This pipe break protection operates self actuated\u00a0 without\u00a0auxiliary energy. In the event of break of the penstock and increased flow\u00a0velocity, the hydraulic butterfly valve closes the penstock automatically by dead\u00a0weight.<\/p>\n<p style=\"text-align: justify;\">The complete installation was commissioned according to time schedule end of\u00a0March.<\/p>\n<\/div><\/section>\n<div  class='avia-video av-av_video-c478bf403dc580572bf7e952870c1e34 avia-video-16-9 av-no-preview-image avia-video-load-always av-lazyload-immediate av-lazyload-video-embed'  itemprop=\"video\" itemtype=\"https:\/\/schema.org\/VideoObject\"  data-original_url='https:\/\/www.youtube.com\/watch?v=ZMRZl41QIlY'><script type='text\/html' class='av-video-tmpl'><div hcb-fetch-image-from=\"https:\/\/www.youtube.com\/watch?v=ZMRZl41QIlY\" class='avia-iframe-wrap'><iframe loading=\"lazy\" width=\"1500\" height=\"844\" src=\"https:\/\/www.youtube.com\/embed\/ZMRZl41QIlY?feature=oembed&autoplay=0&loop=0&controls=1&mute=0\" frameborder=\"0\" allowfullscreen><\/iframe><\/div><\/script><div class='av-click-to-play-overlay'><div class=\"avia_playpause_icon\"><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":3,"featured_media":1375,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[],"class_list":["post-1551","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-common-news"],"_links":{"self":[{"href":"https:\/\/wb-hydro.de\/en\/wp-json\/wp\/v2\/posts\/1551","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wb-hydro.de\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/wb-hydro.de\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/wb-hydro.de\/en\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/wb-hydro.de\/en\/wp-json\/wp\/v2\/comments?post=1551"}],"version-history":[{"count":0,"href":"https:\/\/wb-hydro.de\/en\/wp-json\/wp\/v2\/posts\/1551\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/wb-hydro.de\/en\/wp-json\/wp\/v2\/media\/1375"}],"wp:attachment":[{"href":"https:\/\/wb-hydro.de\/en\/wp-json\/wp\/v2\/media?parent=1551"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/wb-hydro.de\/en\/wp-json\/wp\/v2\/categories?post=1551"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/wb-hydro.de\/en\/wp-json\/wp\/v2\/tags?post=1551"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
