BS 7609 is intended to give guidance to manufacturers and contractors who use compression and mechanic
11、al connectors to enable power cables to be terminated using good engineering practice and to provide quality control guidance for the tools which are used to install connectors. As a code of practice, this British Standard takes the form of guidance and recommendations. It should not be quoted as if
12、 it were a specification and particular care should be taken to ensure that claims of compliance are not misleading. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 12, an inside back cover and a back cover. This standard has been updated (se
13、e copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British S

BSI 2008 BS 7609:1992+A2:2009 The start and finish of text introduced or altered by Amendments No. 1 and No.2 is indicated in the text by tags and . 1 1 Scope This British Standard recommends methods and procedures applicable for the installatio
15、n of uninsulated compression and mechanical connectors for use on copper or aluminium conductors of insulated cables conforming to BS EN 60228:2005 having a cross-sectional area equal to or greater than 10 mm2for copper and equal to or greater than 16 mm2for aluminium. 2 References 2.1 Normative ref
16、erences BS 7609 incorporates, by reference, provisions from specific editions of other publications. These normative references are cited at the appropriate points in the text and the publications are listed on the inside back cover. Subsequent amendments to, or revisions of, any of these publicatio
17、ns apply to this standard only when incorporated in it by updating or revision. 2.2 Informative references BS 7609 refers to other publications that provide information or guidance. Editions of these publications current at the time of issue of this standard are listed on the inside back cover, but
18、reference should be made to the latest editions. 3 Definitions For the purposes of this British Standard, the following definitions apply. 3.1 connector component or assembly of components designed to accept one or more conductor(s) for the purpose of making an electrical connection 3.2 mechanical c
19、onnector assembly designed to clamp conductors by mechanical screw force 3.3 insulation-piercing connector mechanical connector which does not require removal of the conductor insulation to make an electrical connection 3.4 compression connector component designed to make a connection by deformation
20、 of the barrel around the conductor NOTEThe term compression covers the term crimping. 3.5 barrel part of a connector designed to accommodate the conductor 3.6 palm part of a terminal lug formed flat to make a bolted connection to an equipment terminal 3.7 terminal lug connector comprising a palm an
21、d a barrel, for connecting a conductor to an equipment terminal 4 Compression connectors 4.1 Selection of connectors and associated compression dies Each connector should be clearly identified by a reference on the barrel or palm. This reference should enable the user to ascertain whether the fittin
22、g selected is of the correct size and type for the conductor(s) in question; it should also allow the correct die set and compression tool to be selected from the manufacturers recommended list. 4.2 Preparation of a conductor 4.2.1 General The insulation should be stripped back so that when assemble
23、d no insulation can be trapped in the barrel. Care should be taken whilst stripping the insulation to avoid damaging the conductor strands with the stripping tool. The exposed conductor should be cleaned to remove any particles of the insulation material. 4.2.2 Aluminium conductors Unless otherwise
24、stated by the connector manufacturer, the conductor should be thoroughly abraded both to remove surface oxide and create a rough surface to ensure good electrical contact. Suitable abrasives are aluminium oxide cloth Grade 80 or a stainless steel wire brush; separate brushes should be kept for coppe
