31、 clauses common to all the above Guides giving the provisions of a non equipment specific nature for use in the procurement of power station plant. EN 45510 is the responsibility of JTFPE. The so called “common clauses”, as appropriate, also appear in italics in the documents specific to particular

32、equipment. Where parts of the “common clauses” are omitted, this is indicated by the symbol *. Where minor changes have been made to sentences in the “common clauses” these are marked by a vertical line in the left margin. In this Guide, words in bold type indicate that they have the meaning given i

33、n the definitions, clause 3. In this Guide, words and sentences not in italics are specific to this Guide and refer to the particular equipment covered. EN 45510-2-8:2004 - 6 - 1 Scope This standard gives guidance on writing the technical specification for the procurement of low voltage (LV) and med

34、ium voltage (MV) power cables for use in electricity generating stations (power stations). This Guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations. Other possible applications of such equipment have not been considered in the prep

35、aration of this Guide. This Guide covers power cables only for voltages up to and including U m = 41,5 kV. This Guide does not cover cables for public distribution systems, control and instrumentation systems or communications systems. For guidance on the technical specification of cables, including

36、 their installation and termination, refer to EN 45510-2-6 The equipment covered by this Guide is defined by its function rather than design type. Therefore, the guidance to the specification is stated in performance terms rather than being specified by a detailed description of the equipment to be

37、supplied. This Guide indicates to potential purchasers how their specification should be prepared so that: the equipment type and capacity interfaces correctly with other elements of the systems; predicted performance is achieved; ancillary equipment is properly sized; reliability, availability and

38、safety requirements are achieved; proper consideration is given to the evaluation process and the quality measures to be applied. This Guide does not determine the type of specification (e.g. detailed, performance, functional) or the extent of supply for any given contract which is normally decided

39、on the basis of the purchasers project strategy. It does not cover: any commercial, contractual or legal issues which are normally in separate parts of an enquiry; any allocation of responsibilities which are determined by the contract. This Guide does not prescribe the arrangement of the documents

40、in the enquiry. NOTE As a comprehensive European environmental policy is still under preparation, this Guide does not address the environmental implications of the equipment. 2 Normative references The following referenced documents are indispensable for the application of this document.

The specification should define any additional technical terms not included in IEC 60050 (461) or the normative references.
