Adjustable aeration gate for electric transformation base station, has three longitudinal girders, where two of girders are consecutive in stack direction and respectively includes lower and upper edges to define air passage traversing gate

摘要

The gate (50) has three longitudinal girders (52) stacking one on another according to a direction of a stack (66). Two of longitudinal girders are consecutive directly in the stack direction and respectively presenting a lower edge and an upper edge in a manner to jointly define an air passage (70) traversing the aeration gate. The lower edge and the upper edge respectively comprise two recesses (54b, 54a) to form the air passage. An independent claim is also included for a method for manufacturing an electric transformation base station.
