"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."

"Penggunaan ilmu listrik secara benar, terpadu, terkendali dan tepat guna akan memberikan dampak dan manfaat yang sangat besar pada kehidupan masyarakat luas yang telah dirasakan sampai saat ini.
Namun pemakaian listrik tidak terkendali yang diakibatkan oleh pemakainya sendiri serta banyaknya penyimpangan ? penyimpangan dalam penggunaan energi listrik telah banyak menimbulkan bencana kebakaran. Hampir 80% didalam pemberitaan media cetak ataupun media elektronik berita bencana kebakaran sering disebar luaskan karena diakibatkan hubungan singkat arus listrik (korsleijting), bahkan sering pernyataan ? pernyataan tersebut dilansir oleh pihak ? pihak yang berwenang justru sebelum penyidikan dan penyelidikan mendalam dilakukan.
Memang bukan suatu hal mudah untuk membuktikan bahwa suatu penyebab kebakaran bukan diakibatkan oleh listrik, apalagi kebakaran dan jilatan api menghabiskan semua bangunan. Namun perlu diingat bahwa jilatan dan jalaran api mempunyai pola tertentu, terutama yang diakibatkan oleh listrik yang panasnya berasal dari dalam kabel (internal) dan bukan dari luar kabel (eksternal).
Dalam penulisan tesis ini akan difokuskan kepada penilitian terhadap jenis sambungan kabel listrik dalam menanggung beban listrik terutama pada kabel listrik dan sambungannya yang banyak dipakai disektor rumah tinggal, karena penyimpangan paling banyak pemakaian listrik adalah disektor perumahan ini. Penyimpangan ? penyimpangan yang terjadi dalam penggunaan kabel listrik dan cara penyambungan inilah yang banyak menimbulkan bencana kebakaran terutama pada penyambungan.
Dimana pada akhir tulisan ini metoda cara mebuktikan bahwa bencana kebakaran yang terjadi, yang diakibatkan oleh listrik terutama pada beban lebih atau arus listrik hubungan singkat mempunyai pola ? pola tertentu yang mana dapat digunakan oleh forensik sebagai salah satu alat untuk penyidikan dan penyelidikan kebakaran.

Application of electric technology in the right way, integrated, controllable and useful will impacted and benefit in human life to date.
However deviations in application and uncontrollable usage by user itself in electrical power occurred the fire disaster. Almost 80% news that published by the media build the public opinion that fires occurs caused of the electric wire short circuit. Often the officially statement gave by the authority before the fire have been not investigated.
Bearing out the fire caused by electrical installation are not easy, even the fire destroyed all the building. However every single fire will leaving specific debris. Fire leaving the specific pattern in the wall or ceiling that will useful for fire investigate especially the fire cause by the electrical wiring installation, after all the conclusion will found that fire caused by the electrical installation or the electrical installation is the victim.
These thesis will be focused to the research of the type of electrical cable jointing and how it handle the electric load that will be product specific heat inside the cable, especially the cable jointing that applied in the housing due to the most deviation of application in electrical installation coming from these sector.
In the end of these thesis will giving the illustration the best type of cable jointing and will give specific pattern of fire by electric wire to help forensic field to investigate the fire caused."
