Foreword
This standard takes the form of a recommendation and is therefore entitled a “Guide”.
This Guide for procurement has been prepared by the CEN/CENELEC Joint Task Force Power Engineering (JTFPE) of which the secretariat is held by the British Standards Institution.
The text of the draft was submitted to the formal vote and was approved by CEN and CENELEC as EN 45510-2-8 on 2001-03-06.
The following dates were fixed:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2005-03-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-03-01
This Guide for procurement has been prepared under mandates given to CEN and CENELEC by the European Commission and the European Free Trade Association.
This Guide for procurement is a part of a series of Guides mandated to cover the procurement of power station plant and equipment in conformity with European Procurement Directives. The Guides are:
EN 45510: Guide for procurement of power station equipment
Part 1: Common clauses
Part 2-1: Electrical equipment - Power transformers Part 2-2: Electrical equipment - Uninterruptible power supplies Part 2-3: Electrical equipment - Stationary batteries and chargers Part 2-4: Electrical equipment - High power static convertors Part 2-5: Electrical equipment - Motors Part 2-6: Electrical equipment - Generators Part 2-7: Electrical equipment - Switchgear and controlgear Part 2-8: Electrical equipment - Power cables Part 2-9: Electrical equipment - Cabling systems
Part 3-1: Boilers - Water tube boilers Part 3-2: Boilers - Shell boilers Part 3-3: Boilers - Boilers with fluidized bed firing
Part 4-1: Boiler auxiliaries - Equipment for reduction of dust emissions Part 4-2: Boiler auxiliaries - Gas-air, steam-air and gas-gas heaters Part 4-3: Boiler auxiliaries - Draught plant Part 4-4: Boiler auxiliaries - Fuel preparation equipment Part 4-5: Boiler auxiliaries - Coal handling and bulk storage plant Part 4-6: Boiler auxiliaries - Flue gas desulphurization ( De-SOx) plant Part 4-7: Boiler auxiliaries - Ash handling plant Part 4-8: Boiler auxiliaries - Dust handling plant Part 4-9: Boiler auxiliaries - Sootblowers Part 4-10: Boiler auxiliaries - Flue gas denitrification (De-NOx) plant

Part 8-1: Control and instrumentation
EN 45510-1 contains those 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 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 in 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.

Scope
This standard gives guidance on writing the technical specification for the procurement of low voltage (LV) and medium 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 preparation of this Guide.
