Abstract
A composite profile spacer for use in compressed gas insulated co-axial electrical cables. The cables have a central conductor and an outer envelope conductor and an insulating gas contained therebetween. The spacer comprises a composite profile shaped body formed of an electrically insulating material and extends radially between the central conductor and the envelope conductor to support the central conductor substantially concentric with the envelope conductor. The body has a disc section configuration in a first support section adjacent the central conductor, and a cone-section configuration in a remaining support section extending to the envelope conductor whereby to obtain substantially uniform field distribution and low field intensity on the opposed surfaces of the spacer. The contact angle between the opposed surfaces and the central conductor is approximately 75.degree. and the insulating material is an epoxy having a relative dielectric constant of 5 or higher.
