With the Government of China's proposed Energy Efficiency Regulations (GB40411-2007), the implementation of external insulation systems will be mandatory in China. The frequent external insulation system fires cause huge numbers of casualties and extensive property damage and have rapidly become a new hot issue in construction evacuation safety in China. This study attempts to reconstruct an ac...

Brooke, 0. G. (1973). Archives of Disease in Childhood, 48, 901. Thermal insulation in malnourished Jamaican children. The mean summed skinfold at 6 sites in 20 malnourished Jamaican children was 24 5 mm on admission to hospital and 49 8 mm on discharge. Marasmic children initially had thinner skinfolds than children with oedematous malnutrition, and they had a highly significant reduction in t...

Standard No. EN 15831:2004 provides 2 methods of calculating insulation: parallel and serial. The parallel method is similar to the global one defined in Standard No. ISO 9920:2007. Standards No. EN 342:2004, EN 14058:2004 and EN 13537:2002 refer to the methods defined in Standard No. EN ISO 15831:2004 for testing cold protective clothing or equipment. However, it is necessary to consider sever...

The data in this article are the simulation results of 1248 cases that were carried out to detect anti-insulation behaviour in the article titled "Anti-insulation mitigation by altering the envelope layers' configuration" (Idris and Mae, 2017) [1]. These cases are generated by a matrix of 13 climates, 6 envelope layer configurations, 4 occupancy profiles and 4 levels of insulation thickness. Th...

The problem of minimizing the maximum temperature of a structure insulated by a functionally graded metal foam insulation under transient heat conduction is studied. First, the performance of insulation designed for steady-state conditions is compared with uniform solidity insulation. It is found that the optimum steady-state insulation performs poorly under transient conditions. Then, the maxi...

This paper focuses on the space charge behavior in oil-paper insulation systems used in power transformers. It begins with the importance of understanding the space charge behavior in oil-paper insulation systems, followed by the introduction of the pulsed electrostatic technique (PEA). After that, the research progress on the space charge behavior of oil-paper insulation during the recent twen...

Cold protective clothing was studied in 2 European Union projects. The objectives were (a) to examine different insulation calculation methods as measured on a manikin (serial or parallel), for the prediction of cold stress (IREQ); (b) to consider the effects of cold protective clothing on metabolic rate; (c) to evaluate the movement and wind correction of clothing insulation values. Tests were...

Development of effective electrical magnetohydrodynamic (MHD) coating insulating induced current path is one of key fusion technologies for fusion blanket research and development. Electrical insulation coating is extremely important for lead lithium (PbLi) MHD thermofluid study from pointview of secure electric insulating wall condition. The alumina (Al2O3) coatings fabricated by a sol-gel met...

Abstract: The application of electric field theory to widely different aspects of electrical insulation has led to more understanding the phenomena. Electric fields may be considered as the main reason for insulation failure. The purpose of this paper is to modify importance of analyzing electric field in insulation design. The SF6 circuit breaker is chosen as case study that encounters cri...

The thermal insulation market is dominated by petroleum insulations. A gap has been identified for the manufacture of “green” insulations. These insulations must perform to the same levels of heat transfer resistance as their petroleum based counterparts. Modern petroleum derived insulations can be carcinogenic, toxic to manufacture and release toxins as they degrade. The majority are not envir...
