10、ndard has been prepared by Technical Committee MRE/14. It supersedes BS3454:1984 which is withdrawn. Previously the flameproof enclosures were required to conform to BS4683-2:1971; in this revision the opportunity has been taken to update the standard to the requirements of BS5501-5:1977, which is i
11、dentical with the European Standard EN50018:1977. The1984 edition of this standard allowed an arrangement with a centre pilot contact tube but did not specify requirements. As a result two British manufacturers each developed their own design of pilot contact tubes. This revision allows these to be
12、accommodated. This is a companion standard to BS3905:1995, which covers3.8/6.6kV couplers and adaptors. Attention is drawn to the Health and Safety at Work etc. Act1974 1, the Mines and Quarries Act1954 2, the Regulations made under these Acts, and also any other appropriate statutory requirements o
13、r byelaws. These place responsibility for complying with certain specific safety requirements on the manufacturer and the user. The addresses of the recognized certification authorities in the UK for Group I (mines susceptible to firedamp) apparatus for flameproof purposes are as follows. Health and

Users of British Standards are responsible for thei
15、r correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi and ii, pages1 to28, an inside back cover and a back cover. This standard has been updated (see c
16、opyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS 3454:1995 BSI 06-1999 1 1 Scope This British Standard specifies requirements for300A bolted flameproof cable couplers and adaptors of semi-screened three-phase, or unsc
17、reened three-phase with centre pilot tube type, with the following voltage ratings: 1.9/3.3kV; 380/660V and640/1100V. The couplers are designed to enable two cables to be coupled together or to enable a cable to be coupled to apparatus by use of adaptors, in both cases the electrical connections bei
18、ng made by separate connecting pins. Provision is also made for insulated end covers. The use of other forms of intermediate box, with coupling arrangements as specified in this standard, are not precluded provided that all other relevant requirements of this standard are met. The semi-screened cabl
19、e couplers are primarily intended for use with three or four-core wire armoured cables where the fourth conductor is earthed. The cable couplers incorporating a centre pilot are primarily intended for use with three-core wire armoured cables having an additional pilot core(s). Couplers and adaptors
20、conforming to this standard are not intended to be coupled or uncoupled when the circuit is energized. The dimensions necessary to provide for the connection of enclosures of different manufacture and some electrical and mechanical requirements are specified. This standard does not, however, purport
21、 to specify a fully detailed design. NOTEThe figures in this standard show only those essential features and dimensions for function and interchangeability. Dimensions are in millimetres. 2 References 2.1 Normative references This standard incorporates, by dated or undated reference, provisions from
22、 other publications. These normative references are cited at the appropriate points in the text and the publications are listed on page28. Subsequent amendments to, or revisions of, any of these publications apply to this standard only when incorporated in it by updating or revision. 2.2 Informative
23、 references This standard 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 reference should be made to the latest editions. 3 Definitions For the purposes of this B
