Capture trough for ground contaminating liquids e.g. oil and insulating fluids especially for transformers, has stiff foil bent to form captive space

摘要

A capture trough placed under a transformer filled with insulating liquid for possibility of leakage of the insulating fluid. The captive trough has four frame limbs (11-14) forming a frame (10) and a stiff but flexible foil bent to form the captive space placed in the frame (10).
