HELP! What is an ASKAREL TRANSFORMER? What is the use of a condulet?

Question

i really need your help!

i have researched but i couldn't find any info.

thanks

Answer 1

Askarel is one trade name of a PCB insulating fluid in transformers.

Commercial PCB mixtures were marketed as Apirolio in Italy, Aroclor by Monsanto in USA and UK, Asbestol in USA, Askarel in USA and UK, Bakola131 in USA, Chlorextol in USA, Clophen by Bayer in Germany, Delor in Czechoslovakia, Fenclor in Italy, Hydol in USA, Inerteen by Westinghouse in the USA, Kanechlor by Kanegafuchi in Japan, Noflamol in USA, Phenoclor and Pyralene by Prodolec in France, Pyranol and Pyrenol by General Electric in USA, Pyroclor in UK, Saft-Kuhl in USA, Santotherm by Mitsubishi in Japan, Sovol and Sovtol in the former USSR, and Therminol in USA.

PCB fluids were manufactured up through 1977 in the US.  Follow the link below to read details regarding PCB fluid usage in other countries.

PCBs were used as coolants and insulating fluids for transformers and capacitors, stabilizing additives in flexible PVC coatings of electrical wiring and electronic components, pesticide extenders, cutting oils, flame retardants, hydraulic fluids, sealants (used in caulking, etc), adhesives, wood floor finishes, paints, de-dusting agents, and in carbonless copy paper.

The desirable traits of PCB fluids include a high dielectric constants, very high thermal conductivity, and high flash points (170-380°C).

Answer 2

A Askarel Transformer is one that uses a PCB or

PBB liquid as it's cooling/insulating agent.

They are 'bad news' because those liquids are

classified as carcinogenic toxic waste and must

be carefully disposed of by special licensees. (expensive).

A condolet is a conduit fitting, (generally an elbow),

designed to facilitate the pulling in of the cable.
