Compounds are a high dielectric strength filler material used in terminations, cable heads, cable boxes and cable joints. An ideal compound should be chemically inert, adhesive and tacky; have low melting point to permit flow into all unoccupied space before solidifying, low moisture absorption, low dielectric loss, high dielectric strength and high flash and fire point for personnel safety. The selection of the proper compound for a particular installation depends upon: 1. Cable type and kind of insulation 2. Operating voltage and temperatures 3. Cable system elevation differentials (PILC cable only) Types of Compound NOVOID "A" - a medium soft asphaltic base compound recommended for use in most termination and cable head (switch or box) installations at 38kV or below. NOVOID "C" - a medium hard asphaltic base compound recommended for use in terminations and cable heads for application in hot climates or hot exposure at voltages up to and including 38kV. NOVOID "X" - a hard resin-base, oil insoluable compound recommended for use in terminations, cable heads and joints where migration of the cable-tape impregnant may be a problem. There are temperature limitations. NOVOID #224 - a heavy polybutene base compound recommended for use in terminations, cable heads and joints for polyethylene and EPR insulated cables. NOVOID "9A" - a very soft asphaltic base compound recommended for use in spreaderhead installations up to 38kV where the compound must be very fluid to rise up in lead or copper tubes. The lower part of the spreaderhead may be filled with NOVOID "X" to provide a barrier to help prevent migration of the NOVOID "9A" down into the cable. NOVOID #219 - a medium viscosity oil recommended for use as a "flushing compound" for building cable splices or terminating where such "flushing" is required. It may also be used as a filling compound in terminations and and joints on solid type paper insulated cables where oil filled accessories are desired. OZITE "B" - a medium soft asphaltic base compound recommended for use in terminations or cable heads.
