Cables aflame at 1100 °C to test fire resistance

" If the cable itself had adequate fire protection, it would revolutionize this market.

Test cables after completion of the HC fire test. The fire protection is damaged but the cables passed the test requirement of functioned for 30 minutes at 1100 °C.

SP Brand Engineering (SPBE) and SINTEF Energy have a "hot" cooperation. SPBE start a gas fire in their research stove and SINTEF Energy rigs up a high voltage power supply. A cable manufacturer has developed a novel fire-resistant high voltage cable and wants to test the performance. The cable is supposed to withstand 1100 °C for at least 30 minutes at service voltage...without failure.

Fire-resistant cables are often required and at some locations the requirements include what is called hydrocarbon fire, i.e. risk of burning oil and gas. Typical locations are offshore, ships and processing plants. The usual way to protect cables in such areas is to "box" them in, which is terribly expensive due to extra weight, volume, ventilation and maintenance.
