Product description

The HV series is the core of the CEDASPE portfolio, with the widest range of available designs and customizations. This bushing type is widely used for insulating power transformers on the low-voltage side in both indoor and outdoor applications. For example, CEDASPE has supplied more than 10,000 pieces in 2017.
The HV series are solid porcelain liquid filled (hollow core oil communicating) designed in accordance with the standards EN 50180 and EN 50243 (formerly DIN 42531-2-3-4 & 42541).
Transformer oil fills the space between the conductor (a rigid cylindrical copper stem) and the porcelain, increasing the electrical insulation and dissipating the thermal energy generated by the high current.

Featuring an extensive range of available customizations, the HV bushing can be manufactured according to almost any kind of customer requirement (i.e. rod extension, special connectors, special finish surface, etc.)
Designed for both indoor and outdoor applications, the HV bushing series can even operate under extreme environmental conditions (i.e. very polluted areas, very cold/hot ambient temperatures, very corrosive/aggressive environments, etc.).
HV bushings were one of the first products manufactured by CEDASPE from the beginning—a success story supported by extensive experience and deep technical knowledge of the application field.
Lastly, the CEDASPE HV series bushing has the same overall dimensions as the corresponding new SBC bushing type, allowing replacement on-site during normal transformer maintenance operations.
