Electrical cables are one of the key components of green building technologies. They are crucial for the operating of many green building technologies (e.g. power transfer from the solar cell to other building electric devices). For fire safety level assessment of electrical cables installed in green buildings are used their fire characteristics. The reaction to fire is the fundamental and most important fire characteristic of electrical cables. Nevertheless, it is used almost exclusively in the prescriptive appro...

This paper deals with new trends in fire testing of electrical cables. At present, the most widely used tests of electrical cables are reaction to fire tests. The cable systems powering electrical devices which have to remain operational for a certain period of time under fire conditions are additionally subjected to circuit integrity maintenance testing. New trends in cable fire tests include tests of critical heat flux, testing the effect of cable inclination, current load, voltage and frequencies to the rate of...
