Foreword
This Technical Specification was prepared by the Technical Committee CENELEC TC 36A, Insulated
bushings.
The text of the draft was submitted to vote in accordance with Subclause 11.3.3.3 of Part 2 of the CENELEC
Internal Regulations and was approved by CENELEC as CLC/TS 50458 on 2005-10-15.
The following date was fixed:
– latest date by which the existence of the CLC/TS
has to be announced at national level (doa) 2006-07-01
The purpose of this Technical Specification is to ensure the interchange ability between capacitance graded
bushings, with comparable technical requirements, from different manufacturers.
The aim is, to reduce the multiplicity of the different designs, only regarding the interchange ability. The
document gives recommendations for mounting flange dimensions, lower part details, current conductor
connections and limits for the overall dimensions. This allows, on the one hand, the manufacturers of
bushings to use normalised solutions within their own type series and on the other, the users to exchange
bushings from different manufacturers and with different years of manufacture.
In the preparation of this Technical Specification information about existing types (especially details of the
design and the dimensions taken mostly from catalogues of the European manufacturers) was the basis for
discussion in WG 4 of TC 36A. The following restrictions were applied:
• technical aspects of the design of different manufacturers and the requirements of users must be
considered for the values of the new Technical Specification regarding the state of art;
• there should be no single effort for one manufacturer or to the exclusion of another;
• no restriction for the technical evolution.
Conformance will require design changes for not only the manufacturer of the bushings but also
transformers. Some changes may require significant modifications along with type tests which are time
consuming and costly. Purchasers of transformers should also review its contents for its impact on their
procurement process. For these reasons, this document will act as a guide or Technical Specification (TS)
during a transitional period. During this period, the contents will act as a guide to manufacturers while
allowing debate in the industry on its effectiveness and value. This transition period will not exceed ten years
at which time its cont
