本标准为撰写发电站（发电站）使用设备技术规范提供指导。本“采购指南”不适用于核电站核反应堆厂区的设备。在编写本指南时，没有考虑到这种设备的其他可能的应用。 本“布线系统指南”涉及广泛的活动，可以通过选择相关部分用于任何或所有这些活动，例如: - 提供电缆支持; - 敷设电缆; - 完成电缆端; 本指南涵盖电缆的安装，包括20,8/36（42）kV的电源以及控制和仪表电缆的供应和安装。电源线的供应由EN 45510-2-8覆盖。 该指南包括安装用于接地和等电位连接到主接地母线（而不是地下接地电极网络）的保护导体电缆。 本指南涵盖的设备由其功能而不是设计类型定义。因此，对规范的指导以性能说明而不是由所提供的设备的详细描述来指定。 这个贵

This standard gives guidance on writing the technical specification for the procurement of equipment 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. This Guide on cabling systems deals with a wide range of activities and may be used for any or all of these activities by selection of the relevant parts e.g.: - provision of support for cable; - laying of cable; - completion of cable ends; The Guide covers the installation of power cable up to and including 20,8/36 (42) kV and the supply and installation of control and instrumentation cable. The supply of power cable is covered by EN 45510-2-8. The Guide includes the installation of protective conductor cable for earthing and equipotential bonding up to the main earthing busbar(s), but not the below ground earth-electrode network. 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 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 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 on the basis of the purchaser's 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 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.
