A Study on Strengthening Standards for Fire Prevention of Anti-freeze Electric Heating Cable

Nowadays, technology rapid development, the living standard of people also is rising, household devices gradually to the trend of electrification development, in the meantime, the fire also increase annually in caused by electrical equipment. The solar energy water heater used more widely, because the product quality, installation and improper use fire in the number of rising sharply. Among them, caused by electric heating cable fault accounts for a bigger chunk of fire, so the identification of electric heating cable fire are particularly important. We can made comprehensive Analysis on electric heating cable trace utilize the technical means of macroscopical method and metallographic method etc., judge its melting nature, can provide strong technical support for fire investigation.

Statistics of cable fire in power plant from 1960’s to 1990’s was carried out at present. Main causes of the fire were analyzed. The external cause accounts for the majority of cable fire. The existed problem in cable fire prevention was summarized; systematic measures from design, construction and operation should be taken into account to reduce the risk of cable fire in power plant.

Неточное определение термина порождает неоднозначное толкование и, как следствие, искажение (неправильный выбор) противопожарных мероприятий. Авторы данной статьи проанализировали несколько наиболее часто употребляемых терминов, используемых в нормативных правовых актах и нормативных документах, и пришли к выводу, что определения многих терминов нуждаются в корректировке, а также сформулировали предложения по изменению определений некоторых терминов и отдельных пунктов Технического регламента о требованиях пожарной безопасности и сводов правил. An inaccurate definition of the term generates the polysemantic interpretation and, as a result, falsification (incorrect choice) of fire prevention measures. The authors of the article analyzed several of the most frequently used terms applied in regulatory legal acts and normative documents. The authors concluded that the definitions of many terms need to be adjusted. The authors also formulated proposals for changing the definitions of certain terms and particular paragraphs of the Technical Regulations on fire safety requirements as well as Codes of Rules.

AbstractWhile it is incontestable that the Great Fire led to a new awareness and to stronger measures to prevent and to fight fires, this was not because it was the worst in a long series of serious fires, but because it was one of the first. London had no really large fires in the four centuries before 1666, but was to experience fifty or more in the following 200 years. This article asks why. Alongside the obvious facts of rapid population growth and the resulting shoddy building, the continued use of timber for housing, and the inadequacy of fire prevention measures, it suggests that the growth of London's maritime trade and the concentration of stores of new types of highly flammable products, particularly along the river, created a new vulnerability to disaster that made earlier forms of fire control inadequate.

The normal operation of the substation is inseparable from the important guarantee of the cable. The cables in the substation are not only widely distributed, but also the cables are flammable and spread easily after fire. Once a cable catches fire, the consequences will be disastrous. Therefore, how to fire the cable becomes an important task for the power system. Many engineers and technicians continue to analyze and study the causes of cable fires, but cable fire accidents still occur from time to time. In order to solve the problem of cable fire protection and existing problems, the article combines actual research and analysis, and gives the most effective and safe cable fire protection method．

The following paper describes the experimental and analytical work that was carried out in the development of a continuous external trawling protection for the Direct Electrical Heating cables for the subsea flowlines on the Kristin Field in the North Sea. The developed trawl protection was able to absorb the required 5.0 kJ energy without damage to the cable. The Kristin field is the most extreme HP/HT subsea field developed in Norway to date (170 degC reservoir temperature and 911 barg pressure). This is the first time that a continuous trawl protection is applied to the full length of a flowline. The normal approach would be burying to avoid interaction with fishing activities, however since this is a HP/HT subsea flowline it was necessary with an extra cooling from unburied pipelines to reduce the riser temperatures.
