Thermal insulators work by trapping bubbles or pockets of gas inside a foam structure. When these cells of gas are filled with moisture, there are significant losses in insulating efficiency. The thermal conductivity of water (at 10 &C) is 0.5 kcal m 1 h 1 &C 1 and that of ice (at 0 &C) is 2 kcal m 1 h 1 &C 1 (about four times the value of water).

After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high pressure flow of sulfur hexafluoride gas, and an arc is struck between them.
