Tag: Tratamiento PCB

A SEA Marconi acaba de concluir um tratamento de desalogenação (executado on-load, com o transformador energizado e sob carga) numa central hidroelétrica na Roménia. Estas atividades são rotineiras para a SEA Marconi, que realiza diariamente, de forma simultânea, entre 20 e 25 tratamentos em transformadores em diferentes regiões do mundo. Neste caso específico, a intervenção foi realizada com sucesso apesar

The first "episode" of this important milestone dates back to May 2020 with the publication of the call for tenders by The Egyptian Environmental Affairs Agency (EEAA) through the agency for the sustainable management of persistent organic contaminants (POPs) in response to the obligations of the Stockholm Convention. www.popsegypt.com The tender, financed by the World Bank / GEF, was entitled: Decontamination of PCB-ContainingLeia mais

As part of the PCB/UNDP/GEF project, Sea Marconi has been invited to present its solutions at the workshop on PCB/POPs treatment (decontamination and disposal), which will be held on 21st and 22nd July 2015 in Brasilia (Brazil). The event will see managers and technical experts gathered together from the energy, industrial, transportation, health, agricultural and other sectors, which all use electrical equipmentLeia mais

The first relations between Sea Marconi and Vietnam date back to 2003, when a technological cooperation agreement was signed on “Clean Technologies” between the European Commission and Asian area. Twelve years later, last 11th and 12th May 2015, we were pleased to host a delegation of the Vietnamese national electricity company, EVN*. Their objective was to select the best technologyLeia mais

We are particularly proud to be able to recount another positive update in the “PCBs free Program for Japan” project: the arrival of the first order for the development of a system (DMU) for the dehalogenation of oils and transformers contaminated by PCBs. To completely understand the extraordinary nature of this news, we need to take a look at theLeia mais

Scenario Hydro Power Plant The transformer is located near a river dam with extreme logistical and environmental constraints. The option of changing the oil was discarded immediately because of the enormous difficulties in handling (see. Photo) around the transformer. At the same time the fuller earth techniques would not solve the functional criticalities of the system “oil – transformer”. NameplateLeia mais
