Cable trunking systems and cable ducting systems for electrical installations - General requirements Ingestion-build-260237 BS 1881-131 guides you through1 Scope This European Standard specifies requirements and tests for cable trunking systems (CTS) and cable ducting systems (CDS) intended for the accommodation, and where necessary for the electrically protective separation, of insulated conductors, cables and possibly other electrical equipment in electrical and or communication systems installations. The maximum voltage of these installations is 1 000 V a. c. and 1 500 V d. c. This standard does not
