Abstract: A series of laboratory tests for electrical fires
have been carried out by researchers, and some of the results have confirmed
and been adopted as standard. However, the studies focus on electrical fires in
PVC insulation material and the melting temperature and toxicity of PVC
insulation. By focusing on heat conductors, the growth and spread of a fire can
be eliminated by reducing the oxygen concentration, especially inside the
compartment. Electrical fires are the most common cause of compartment and
building fires both internationally and nationally, according to statistics
(Liu & Benichou, 2008). Whatever the triggers are inside the electrical compartment on
the connection, termination, or cable, this research looks into electrical
fires caused by 1.0–1.5 mmsq electrical cables. Electrical fires in cables are
normally started by increasing temperatures inside the cable conductor. By
controlling and adjusting the oxygen concentration inside the electrical
compartment under atmospheric concentration, one can hamper a fire’s start,
trigger, propagation, and growth. This study investigates the effectiveness of
oxygen concentration on preventing the growth of fires triggered by electrical
cabling. A series of studies were created in laboratory scale in a horizontal
compartment with oxygen levels of 19%, 17%, and 15%. This paper presents the
results of this experiment by studying the effects of reducing oxygen
concentration on the fire growth in cable network in a horizontal orientation.
The results show that controlling the oxygen concentration at levels lower than
atmospheric concentrations can effectively reduce the propensity for cable
ignition and lower the fire propagation rate.
