Claim 3

The assembly as defined in claim 1 and including a ceramic insulator surrounding said outer insulator in spaced relation thereto; and liquid insulating material filling such space.

Claim 4

The assembly as defined in claim 2 wherein said insulators are wound of fibrous insulating material which is saturated with set and cured synthetic resinous material.

Claim 5
