Professional dismantling of gas-filled GIS systems
Dismantling and disposal of SF6 GIS and GIL systems
The dismantling of switching and pipe systems filled with SF6 gas requires a great deal of experience and the appropriate equipment. A GIS system or a GIL system contains large quantities of SF6 gas. The different parts of the system are protected by various safety devices ensuring no SF6 gas can escape during operation, even in the event of malfunctions.
The dismantling of gas-filled GIS systems and GIL systems therefore requires precisely coordinated extraction of the various system components in the correct sequence to avoid excessive pressure differences. Our sister company SF6 Recycling GmbH has specially designed high-performance extraction units that are extremely compact and specifically designed to safely extract large quantities of SF6 gas in a short time. We own a large number of 600 liter pressure tanks to temporarily store several tons of SF6 gas until it is professionally recycled. If needed, we are happy to return the purified SF6 gas to you in a desired quality that far exceeds the specifications of IEC 60376. The quality of the processed SF6 gas can be tailored to your requirements.
Our employees have both the knowledge and the experience in dismantling complex oil-filled and SF6-filled switchgear so that we can dismantle your GIS and GIL systems on a project-specific basis and supply the system components to recycling. For us, it goes without saying that active system components are physically separated before dismantling. We have already dismantled numerous GIS and GIL systems in narrow inner-city locations or in cavern power plants. As we only work in the electricity industry, we are familiar with the special occupational health and safety and environmental protection requirements of our customers. With our own vehicles and equipment, we react quickly and flexibly to your requirements.
By recycling both the SF6 gas and the system components in our own approved recycling plants, you can be sure that all legal requirements are met. As a certified waste management company, our processes and disposal routes are regularly audited so that you can be sure that you are fulfilling your operator obligations.
What can we do for you?
Dismantling of switchgear
We offer complete dismantling and disposal solutions for partial and complete conversions of transformer substations. We undertake the complete demolition and dismantling and recycle scrap as well as copper cables and the dismantled hazardous waste such as transformers, circuit breakers, transformers and oily cables in an environmentally friendly manner in our own recycling plant. We also evacuate SF 6 gas-filled plant components before transportation in accordance with legal regulations.
Dismantling of oily cables
Our teams dismantle your oily cable routes on site and load them directly into suitable containers. We have oil-tight roll-off containers with a volume of 20 cbm in which we transport the cables safely and in compliance with the law. In our approved recycling facility, we accept high and low-pressure oil cables and recycle them in accordance with the statutory regulations under AVV number 17 04 10. We also accept oil-containing joints or cable fittings under AVV 17 02 04.
SF6 gas plants
Especially when it comes to the disposal of SF 6 gas-filled appliances and systems, it is important that hazardous substance- , hazardous goods- and waste regulations are complied with. Depending on the decomposition products contained, very different legal regulations apply, all of which we comply with. We specialize in the disposal of SF6 gas-filled equipment and switchgear and have our own analysis- and evacuation equipment with the appropriate connections for any SF6 gas disposal tasks.
Deconstruction of switchgear
The conversion or dismantling of indoor switchgear poses special challenges in terms of limited space and the removal of hazardous substances. So thought advanced materials were often used at the time of construction that are now hazardous waste when being disposed of. We have the tools and licenses necessary and are able to analyze and dispose of asbestos or PCB-containing adhesives and flooring just as professionally as SF-6 systems or mineral fiber waste. Of course, we will provide you with all required waste disposal documentation once the work has been completed.
Transformer dismantling
We dismantle and recycle transformers of all sizes in our own BImSchG-approved facility. We organize and handle the removal of the transformers and their transport to our grounds. Of course we provide you with the proper waste disposal certificates in accordance with the NachwV. For transformers under 20 tons per source and year, our collective disposal certificate is used.
Moving of large transformers
We have the expertise and equipment to move large transformers from their foundations to a new location or onto a low-loader. We use mobile hydraulic rams, mobile hydraulic pumps as well as the cable winches and hydraulic units of our Unimog to move transformers that cannot be craned due to low roofs or nearby live cables.
