Webbushing. Condenser bushings may be one of several types: 1. Resin-bonded paper insulation; 2. Oil-impregnated paper insulation; or 3. Other. D. Dry or Unfilled Type Bushing.-Consists of porcelain tube with no filler in the space between the shell and conductor. These are usually rated 25 kV and below. E. Oil-Filled Bushing.- A bushing in WebHot collar test: A hot collar test is used routinely for solid type bushings without taps and is effective in revealing deterioration, contamination, low compound or liquid levels, and voids in the compound (if applicable). It may also be effective as a supplementary test to C1 and C2 tests on capacitance-graded bushings with taps. internet movie database knives out
