The CEDASPE HC series bushing 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 250 pieces in 2017.
The HC series are solid porcelain liquid filled (hollow core/solid porcelain open type) bushings designed in accordance with the standards EN 50180 and EN 50243 (formerly DIN 42531-2-3-4 & 42541). HC series bushings feature a copper tube conductor (high-current density conducts the electrical flow entirely along the external copper surface). Transformer oil fills both the rod and the space between the rod 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 HC 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 HC bushing series can even operate under extreme environmental conditions (i.e. very polluted areas, very cold/hot ambient temperatures, very corrosive/aggressive environments, etc.). Furthermore, a top-lifting M12 eye nut has been included in the design for easier handling.
The demand for high-current bushings continues to grow. As the worldwide leader in manufacturing this special bushing type, CEDASPE continues to supply this particular product through constant innovation and improvement of its production capacity.
