Aroclor if. Monsnn to':; brand nonu.; for i Up <\,} vjr.i i (>i ini) >regn i n l composed of oh.lor j nu Led bj phoiny.1 .
Aroclor is classed as a capacitor Asknrel. The term "Askari'l" 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 1929 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, pn 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More repefHri-y--Aroclor 1242 has been replaced by Aroclor 1342. It is ((Identical jto Aroclor 1242 but has been modified to reduce^the 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.

Advantages of Aroclor
1. Capacitors having the least volume aiul mass per
unit of reactive powercan he built.
.
2. Haw materials costs can be reduced because of this higher efficiency,
3. labour costs can be reduced because smaller
windings are required and plant throughput is
increased.
. .
4. Overload security is provided by uniform permittivity of impregnate and paper.
5. Long lasting capacitors result from high stability and resistance to oxidation.
6. Reduced fire ha/qrd.

Storage, Handling and Disposal of Aroelor
Caution

Drums
'
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 greally reduced.
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.
Drum storage areas should be organised so that any leakages arc collected for safe disposal. , .
Even where storage nnd handling facilities aic not at present available, the 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 Aroelor in bulk is available from Monsanto.
Partially emptied drums should not be left open to the air.
Bulk

As soon as a changeover to bulk delivery is contemplated, experienced Monsanto personnel will be available for site discussions regarding the most efficient type of installation for the particular location and an offloading procedure appropriate to that particular installation.

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 1000C minimum with a residence' time of 1.5 seconds or longer or alternatively by a method conforming to local regulations. Empty drums should not be re used for anything except scrap Aroclor. If this is not possi ble each drum should bo ringed twice with kerosene and the washings incinerated as above. Drums should then lie crushed and buried on an approved toxic dump in accordance with local rcgulations.
.
Care must be exercised during such disposals and the ultimate tise of Aroclor to avoid pollution particularly of sewers and waterways.
