This British Standard specifies requirements for 400 A bolted flameproof cable couplers and adaptors of the fully screened 3-phase type with a voltage rating of up to and including 6.6 kV primarily for use in mines. 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. The dimensional and test requirements for cable coupling units also cover conversion units that enable couplers/adaptors complying with this standard to be connected to couplers/adaptors complying with BS 3454 and BS 3905. In all cases the electrical connections are made by separate connecting elements. 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 couplers complying with this standard are primarily intended for use with 3- or 4-core, individually screened, wire armoured cables, where the fourth conductor is earthed.
Couplers and adaptors complying with this standard are not intended to be coupled or uncoupled while the circuit is energized. The dimensions necessary to provide for the connection of couplers of different manufacture and some electrical and mechanical requirements are specified. This standard does not, however, purport to specify a fully detailed design.
Information to be supplied by the purchaser with the enquiry or order is given in Appendix A.
