Aroclor 155 classed as a capacitor Auknrel. The term "Aska n-1" is defined by the American Socei ty for Tost, in-i and m 1'.<] i a Is (ASTM) as Ha generic term for a group of non-Hamnwhlc chlorinated hydrocarbons used as electrical insulating media" .
Aroclor was firdt used in U.S.A. in 1929 and j 5; 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, in 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More repcntly Aroclor 1242 has been replaced by Aroclor 1342. It isridentical jto Aroclor 1242 but has been modified to reduce thfe 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 CIGUE recommendations that capacitor askarels should not contain more than 3.5% of pentachlorobiphenyl and more highly chlorinated biphenyls.

Advantages of Aroclor
1. Capacitors having the least volume aiid mass pet unit of reactive power can he built.
2. prRaw materials costs can be reduced because
this higher efficiency.
i. labour costs can be reduced because smaller
windings are required and plant throughput is
increased.
-
A. Overload security is provided by uniform permittivity of impregnanl and paper.
5. Long lasting capacitors result from high stability and resistance to oxidation.
6. Reduced fire harqrd.

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

Disposal of empty drums and waste Aroclor
Handling Aroclor in bulk will minimise the problems associa ted with handling of drums. Waste Aroclor should be dispo sed of by special high tempe rature incineration at 10O0C minimum with a residence time of 1.5 seconds or longer or si ternatively by a method conforming to local regulations. Kmpty drums should not be re used for anything except scrap Aroclor. If this is not possi ble each drum should be ringed twice with kerosene and the washings incinerated as above. Iirums should then he crushed and buried on an approved toxic dump in accordance with local regulatj ons.
Care must he exercised during
such disposals and the ultimate use oi Aroclor to avoid pollution particular1y of sewers and waterwciys .
