BS 6622 This British Standard specifies requirements and test methods for theconstruction, dimensions and mechanical and electrical properties ofarmoured cables with thermosetting insulation for rated voltages from3.8/6.6(7.2)kV up to 19/33(36) kV inclusive, designed for a maximumcontinuous conductor operating temperature of 90 C and for a maximum short circuit conductor temperature of 250 °C, for use infixed installations such as networks or industrial installations.
This British Standard specifies single-core and three-core cables forvoltages in the range 3.8/6.6 (7.2) kV up to 19/33 (36) kV, with:
a stranded copper,stranded aluminium or solid aluminiumconductor or conductors;
cross-linked polyethylene or cross-linked ethylene propylenerubber insulation;
a metallic screening layer of copper wire or copper tape and/or ametallic armour of aluminium or galvanized steel wire;
a polyvinyl chloride compound (PVC) or polyethylene (PE)oversheath.
NOTE Guidance on the selection of cables is given in Annex A.Information to be supplied by the purchaser, and items to be agreedbetween the purchaser and the manufacturer, at the time of enquiryand/or order, are given in Annex B.Recommendations for the installationof cables are given in Annex C. Guidance on the use of cables is given inAnnex D.
The following referenced documents are indispensable for the application of this document. For dated references, only the editioncited applies. For undated references, the latest edition of the referenced document ( including any amendments) applies.
routine tests tests performed by the manufacturer on each manufactured length ofcable to check whether the whole of each length meets the specifiedrequirements.
sample tests tests performed by the manufacturer on samples of completed cable, orcomponents taken from a completed cable, at a specified frequency, todetermine whether the finished product meets the specified requirements.
type tests tests made before supplying a particular type of cable on a generalcommercial basis, to determine whether the cable has satisfactoryperformance characteristics to be suitable for the intended application.BS 6622 pdf download.
