Abstract (en)
An aspect of the present disclosure provides an electrical bushing 100 with enhanced thermal performance. The electrical bushing 100 includes a central tube 101 having a first emissivity, and a conductor 102 arranged within the central tube 101 providing a gap G between the conductor 102 and an inner surface of the central tube 101, wherein at least a portion of the inner surface of the central tube 101 is provided with a coating having a second emissivity which is higher than the first emissivity. A further aspect of the present disclosure provides an electrical transformer 200 having at least one said electrical bushing 100.
