14、controlgear, was submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60439-5 on 2006-09-01. This European Standard supersedes EN 60439-5:1996 + A1:1998 and EN 50300:2004. The main change with respect to EN 60439-5:1996 is the inclusion of substation cable distribution boards
15、 (SCDBs). The title has therefore been amended. In view of the fact that this publication should be read in conjunction with EN 60439-1:1999, the numbering of its clauses and subclauses correspond with the latter. The clauses of this standard supplement, modify or replace clauses in EN 60439-1. Wher
16、e there is no corresponding clause or subclause in this standard, the clause or subclause of the main document applies without modification. Clauses, subclauses, figures and tables which are additional to those in Part 1 are numbered starting from 101. The following dates were fixed: latest date by
17、which the EN has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2007-06-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2009-09-01 Annexes ZA and ZB have been added by CENELEC. _ Endorseme

21、or assemblies for power distribution in public networks 1 General 1.1 Scope and object Replacement: Substation cable distribution boards (SCDBs) and cable distribution cabinets (CDCs) for power distribution in networks shall comply with all the requirements of IEC 60439-1 (1999) if not otherwise ind
22、icated hereinafter and shall also comply with the particular requirements contained in this publication. This standard gives supplementary requirements for substation cable distribution boards (SCDBs) and cable distribution cabinets (CDCs), which are stationary, type-tested assemblies (TTA). They ar
23、e used for the distribution of electrical energy in three-phase systems. Open- type ASSEMBLY are not covered by this standard. Individual components, such as fuses and switching devices that comply with other standards, shall also comply with the supplementary requirements of this standard. The obje
24、ct of this standard is to state the definitions and to specify the service conditions, construction requirements, technical characteristics and tests for SCDBs and CDCs. Higher performance and test levels may be required for particular networks, for example, those with meshed connections. NOTE 1 If
25、a CDC is equipped with additional equipment (for example meters), in such a way that the main function is changed considerably, then other standards may also apply as agreed between user and manufacturer (see 7.6). NOTE 2 Where local regulations and practices permit, an SCDB or CDC according to this
26、 standard may be used in other than public networks. SCDBs are suitable for installation in places where only skilled persons have access for their use; however, outdoor types may be installed in situations which may be accessible to the public. SCDBs are connected to the low voltage terminals of di
27、stribution transformers by means of connecting bars, rods or cables. CDCs are for outdoor installation in places which are accessible to the public, and where only skilled persons have access for their use. 1.2 Normative references This subclause of Part 1 applies with the following additions: IEC 6
