Being thus made, the parts are quite thin and canbe thoroughly vitrified. A test of 120,000 volts has beenmade upon these insulators without affecting them in the is mounted on a high carbon steel pin with a cap of locustwood. These insulators are matle of high grade materialthroughout and are mechanically and electrically well suitedto stand the arduous service expected of them. HUNT AIR BRAKE NOTES. I. li.
