Product description

The CEDASPE ED series bushings are LV solid porcelain bushings. They have been designed to meet customer needs, offering an easy, fast and reliable solution for the requirements of distribution transformer manufacturers.
The special design of the ED series provides better gasket protection against external environmental conditions (i.e. UV radiation), ensuring a longer service life for the gaskets, thus reducing maintenance costs as well as leakage issues.
The main feature of these low-voltage bushings is a reinforced nylon insulating support on the oil side that ensures an optimal tightening solution. ED bushings have a compact body; the reduced number of components and gaskets produces a smart, fast and easy design that significantly reduces maintenance costs. ED series is suitable for smart assembly, packaging and delivery: each bushing is shipped pre-assembled, saving 30% - 50% of mounting time and reducing cost.
ED bushings are fully interchangeable with the old DIN standard. This simplifies replacement and allows old DIN bushings with the same current rating to be replaced easily, without changing the transformer design.
Featuring an extensive range of available customizations, the ED bushing can be manufactured according to almost any kind of customer requirement (i.e. special rods/connectors, special treatment surface, etc.), unlike the old DIN design.
Designed for both indoor and outdoor applications, the ED bushing series can even operate under extreme environmental conditions (i.e. very polluted areas, very cold/hot ambient temperatures, very corrosive/aggressive environments, etc.).
