A peculiar property of oils, and liquid insulation in general, when subjected to rapidly changing electric stresses, is to disperse any gaseous bubbles which may be present, and diffuse them through its mass, generally long before any injurious break can occur.
Two flitting ghosts hastening to escape from the light of day, could not have seen less, or have felt less sympathy with the warm beautiful scenes through which they were passing. There is no insulation so perfect as that of small, selfish natures preoccupied with a pique.
So far I've only had light shocks, but the insulation is burning out of my magneto, and that will soon stop. When it does I can't run the motor, and " "I'm going to cut that wire!" again shouted Mr. Peterson. "But you can't, without pliers and rubber gloves!" yelled Tom. "Keep away, I tell you!" The man on the ladder hesitated.
The primary and secondary layers are insulated by cotton cloth, the thickness of the insulation, of course, bearing some proportion to the difference of potential between the turns of the different layers. Each half of the primary has four layers, 24 turns in each, this giving a total of 96 turns.
A letter of seven pages of about the same date in 1887 expatiates on the vicious troubles caused by the air-bubble, and remarks with fine insight into the problems of insulation and the idea of layers of it: "Thus you have three separate coatings, and it is impossible an air-hole in one should match the other."
But there was one trouble with the battery which did not reach his eye as he turned it around and started it up. That was that a portion of the insulation of a main wire was worn off. As he turned on the current there was a flash and the light blazed up almost as bright as day. "That's fine!" cried Sam. "We'll be able to see the Flyaway a long distance off now."
He couldn't quite take it in. "This," snapped the red-headed man abruptly, "is a stickup!" Pop's eyes went through the inner lock-door. He saw that the interior of the ship was stripped and bare. But a spiral stairway descended from some upper compartment. It had a handrail of pure, transparent, water-clear plastic. The walls were bare insulation, but that trace of luxury remained.
Substantial fat reserves are helpful as heat-retaining insulation in those rare accidents when someone is dropped into a cold ocean and must survive until the rescue boat arrives. Being fat might keep a person alive longer who is lost in the wilderness awaiting rescue with no supplies, no means of procuring food, and no means of keeping warm.
Furthermore, the structure of the cable, with the flat, flexible insulation between its two conductive surfaces, made it practically impossible to short it out; and the flanged wheels of the scuttlebug clipped over it in such a fashion that, once locked, it was thought to be impossible that they could lose their grip without being unlocked.
These mechanical conceptions well in mind, it is clear that what the would-be liquefier of gases has all along sought to attain is merely the insulation of the portion of matter with which he worked against the access of heat-impulse from its environment.
