Industrial Cables-British Standard
2491X HR to BS 6004(New BS EN 50525-2-31)

Application and Description

These special heat-resistant flexible single-conductor hook-up wires are ideal for use in power current installation, switch cabinets, motors and transformers which are subject to direct contact with high temperature equipments(e.g. varnishing machines and drying towers etc.). These are also suitable for
inside wiring of electrical equipments such as lighting and heating apparatus. 2491X HR is equivalent to harmonized code H05V2-U/H05V2-R/H05V2-K.
