BS 5308 Part 1 Type 1 Unarmoured LSHF Instrumentation

Low Smoke Halogen Free (LSHF) versions of BS 5308 are widely used in industrial and commercial installations where safety to personnel and equipment is critical. The are available with collective aluminium tape screening (CAT) or individual and collective aluminium tape screens (ICAT) to prevent electrical interference from equipment nearby or crosstalk between the pairs.
