AROCI.OR Arcelor .if. Monsanto's brand name ft composed of ohlori nu Led bj pln'iny j . c\puc.i t.< j mj' Aroclor is classed as a capacitor Acknrel. The term "Askare!" is defined by the American Soceity for Testing and Materials (ASTM) as "a generic term for a group of non-flammable chlorinated hydrocarbons used as electrical insulating media". Aroclor was first used in U.S.A. in 1920 and is now extensively used by the capacitor industry throughout the world. Monsanto has been producing Aroclor at its Newport plant since' 1951. Aroclor has been used in impregnated paper capacitors since its introduction into industry, j.n more recent years its use has been extended to capacitors in which polypropylene film forms part of dielectric. Aroclor impregnated capacitors are used mainly to operate at power frequency. Some are used-with water cooling- at high fre quencies and some - with suitable additives - in D.C. circuits. AROCLOR 1342 In recent years most capacitor manufacturers switched their production to use mainly trichloro biphenyl sold under the Monsanto name of Aroclor 1242. The grade offered the best cost performance and was essential for capacitors operating in a cold environment. More repetrfeiy--A^oclor 1242 has been replaced by Aroclor 1342. It is tidentica 1 jto Aroclor 1242 but has been modified to reduce content of highly chlorinated components. The reason for this change is that environmental studies suggest that the more highly chlorinated components, especially those containing five and six chlorine atoms per modecule, are more persistent and therefore more likely to accumulate in the environment. Aroclor 1342 complies with the CIGRE recommendations that capacitor askarels should not contain more than 3.5% of pentachlorobiphenyl and more highly chlorinated biphenyls. 0205330 TOWOLDMON0025075 WATEFLPCB-00009544 Advantages of Aroclor J.

Haw materials costs can be reduced because of this higher efficiency. - 3. labour costs can be reduced because smaller windings arc required and plan! throughput is increased. . 4. Overload security is provided by uniform permittivity of impregnanl and paper. 5. Long lasting capacitors result from high stabilily and resistance to oxidation. 6. Reduced fire hazard.

' Proms \ - Inside storage is recommended to prevent contamination of the product by water. If the drums have to be stored outside they should be slacked on their sides to prevent water accumulating around the bungs and being breathed into the drum during severe ambient temperature changes. Prum storage areas should be organised so that any leakages arc collected for safe disposal. . . with drum deliveries. Unloading, storing and transferring to the production unit is safer, easier, faster and cheaper. Material losses due to spillage and incomplete emptying of drums arc eliminated. The possibility of product contamination during handling is greatly reduced. Fven where storage and handling facilities arc not at present available, the economics of bulk handling may quickly pay for the tanks and piping systems required. A booklet indicating tire type of system necessary for the efficient handling or Aroclor in bulk is available from Monsanto. Partially emptied drums'should not be left open to the air.
