Busbar arrangement for cooling the housing of low pressure turbine of a jet engine gas turbine

Jet engine gas turbine channel main stream (20) and a carcass structure (22) surrounding radially the channel mainstream, in which flows a gas stream of the housing in the same direction as the main current in the channel main stream, wherein the housing structure having an array of current conduction (25, 25 ') adjustable, which can be adjusted the flow of gas stream carcass to and / or along the channel mainstream, wherein the arrangement of current conduction (25) comprises at least one baffle plate outlet (26), which divides the gas stream from the casing in at least two partial flows, where a substream passes near channel mainstream and other distant partial channel current mainstream, characterized in that the current conducting plate (26, 26 ') is configured for adjustable and l substreams variable adjustment and / or has closable openings variables.
