Stay Protected from Electrical Fires

The BIS authorities, in order to keep pace with the changes in the International specification, applications and usage conditions in India, have been revising the IS 694 Standard from time to time to keep the industry and consumers abreast with these changes. The last (4th) revision of IS 694 took place in the year 2010, and this revision though long overdue, sets norms which are in tune with international specifications. The IS 694: Revision 4: 2010 forms a major basis of our analysis in this article. - Vimal Kumar Chopra

Self Regulating Heat Tracing Cable

Self-regulating trace heater cables on roofs or gutters are used to melt ice during winter months. When used in gutters the cable is not meant to keep the gutters free of ice or snow, but only to provide to free path for the melted water to get off the roof and down the downspout or drain piping. Similarly, hot water service piping can be traced, so that a circulating system is not needed to provide hot water at outlets. The combination of trace heating and the correct thermal balance where the heat output from the trace heating matches the heat loss from the pipe. Self –limiting or regulating tapes have been developed and are very useful in this application. In this paper authors like to discuss about development, uses and product classification approach to measure the temperature class of thermopads make self-regulating type trace heater model STF 15 J. - Navin Kumar, A.

Preventing Electrical Fires

Shockingly, almost 90 percent of all fire accidents originate from “electrical” causes, and behind a vast majority of these fires are low-quality wires and cables, that is, either low-quality insulation or inferior conductor or both. The article provides a snapshot of how consumers, consultants, specifiers and decision-makers can avoid dreadful consequences by choosing the right kind of wires and cables. - Pratap M Anam
