Industrial Cables Single Core Fixed Wiring Cable
2491X Heat Resistant cables to BS 6004
Application and Description
2491X Heat Resistant cables to BS 6004 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.). 2491X Heat
Resistant cables to BS 6004 cables are also suitable for inside wiring of electrical equipments such as lighting
and heating apparatus. 2491X HR is equivalent to harmonized code H05V2-K/ H07V2-K.
