LF-249 Flexible Single Core Cable

2491B and 6701B are flexible single cores with class 5 stranding conforming to the harmonisation standard H05Z-K and H07Z-K for Low Smoke Halogen Free single core cable. Applications include panel and conduit wiring where its flexibility makes installation easier.

Public and government buildings are increasingly using LSHF cabling to reduce the risk of injury through smoke inhalation in the event of a fire. The cables also produce less corrosive gases when burnt, which is particularly important where sensitive electronic equipment is installed such as in computer rooms.
