2491X HR to BS 6004(New BS EN 50525-2-31)
Application and Description
2491X HR to BS 6004(New BS EN 50525-2-31) cables 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.). 2491X HR to BS 6004(New BS EN 50525-2-31) cables 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.
