Potential energy rail line for production of electrical energy from e.g. wind turbines, has connection surface in which recesses are formed, such that self inclination angle of recess is smaller than arc tangent of recess

摘要

The potential energy rail line (14) has a rectangular main structure (14a) made of brass. The main structure is provided with a connection surface (14b) in which recesses (16) are formed as tapered blind holes. The connecting units are plugged into the respective recesses so as to connect the cables. The self inclination angle of recess is smaller than the arc tangent of recess such that static friction coefficient is receivable between recess and connecting unit. An independent claim is included for electrical connection system.
