Our EKTO transformer oil bushing is a solution that was specifically developed for use in the oil environment. The product is designed to come into contact with both transformer oil and cable connection box oil. The solid active part of the oil-free transformer bushing is made of resin-impregnated paper. The bushing has a condenser control and is particularly suitable for installation in cable connection boxes. The test tap is provided by means of a connection line. The EKTO bushing is designed for rated voltages of 36 to 800 kV and rated currents up to 4000 A.
Design
Intended for the direct connection of power transformers to oil filled cable boxes, the type EKTO has an insulating body of resin impregnated paper (RIP). The condenser core is made of special paper epoxy resin vacuum-impregnated paper. Conductive layers made of aluminium foil are inserted between these paper layers for grading the electric field. Thanks to their good conductivity, optimum voltage distribution is guaranteed even in case of rapid voltage changes.
