About the issue of PCB

bout PCB, new production, use were called off by administrative advice (afterwards laws and regulations) of the Ministry of International Trade and Industry in 1972. PCB pollution of around dozens of mg/kg was confirmed about electric apparatuses told not to use PCB made after it and was announced in 2002.

It becomes clear that a very small amount of PCB mixture being extensive pollution to be started from use of reproduction insulating oil, pollution cause last for the life cycle whole of insulating oil according to “a very small amount of PCB pollution cause investigation report” of low-concentrated PCB pollutant measures Exploratory Committee installed by Ministry of Economy, Trade and Industry, Ministry of the Environment (May 10, 2004 announcement), and plural number exists.

In the case of electric apparatuses which we aim at such a PCB and do not use, we cannot make a PCB-containing decision in model, tablet.

About a very small amount of PCB mixture about electric apparatuses owned by visitor, please confirm “about transformer which cannot deny possibility of a very small amount of PCB mixture”.

About use of PCB transformer

In us, it does not produce transformers using PCB oil.

About transformer which cannot deny possibility of mixture of note) very small amount PCB (a very small amount of PCB mixture transformer)
 It was not oil transformer using PCB, but, at the time of insulating oil production, we said transformer considered that a very small amount of PCB got mixed with insulating oil in at the time of transportation and originally became clear intentionally in 2002.

※About transformer which cannot deny possibility of mixture of a very small amount of PCB, please confirm about 「 “transformer which cannot deny possibility of a very small amount of PCB mixture”」and「“flow (figure of flow) of distinction method and correspondence of a very small amount of PCB mixture transformer”.

With a very small amount of PCB mixture transformer

A very small amount of PCB mixture transformer was not originally oil transformer using PCB intentionally, but we said transformer considered that a very small amount of PCB got mixed with insulating oil in at the time of insulating oil production, transportation and became clear in 2002. About findings about a very small amount of PCB mixture to transformer made in us, please see “More details are here”.
