Introduction
Electro-Magnetic fields (EMFs) are produced by the use and distribution of electricity as all cables that carry power emit EMFs. EMFs are composed of both electrical fields and magnetic fields. The company is introducing a patented, unique new technology called “Extremely Low Magnetic Field” (ELMF) that when implemented, drastically reduces the EMFs that are being created.
EMFs are linked to serious health problems so legislation has been increasing globally. California now has restrictions on the distance power lines can be from schools and hospitals and the World Health Organisation (WHO) has created the “ALARA” (As Low As Reasonably Possible) policy to start to combat this issue. EMFs also cause engineering issues, which need to be designed out of products because they can potentially be dangerous in certain applications. This adds both personnel and material cost as well as being very inconvenient when developing products.
Green Cables eliminates the health and engineering issues due to its unique patented technology. The technology saves significant design cost as there is no need to create complex EMF reducing solutions and manufacturing costs are reduced as fewer materials are required in the new ELMF solution.
Green Cables are set to revolutionise the cable and distribution board business globally.
Recognising the growing trends towards “Green” technologies, the three principals formed Green ELMF Cables Ltd., as a technology transfer company, in order to bring to the market these technology advancements.
Green ELMF is a technology transfer company that doesn’t plan to own production facilities, but rather to cooperate with manufacturers in the cable industry with open and non-compete agreements. Green ELMF Cables Ltd sees a large commercial potential in this direction, but it also believes that this technology carries the promise of a solution to one of today’s most difficult problems– the electromagnetic field effects.
The Need
Electromagnetic Fields (EMFs) are a natural consequence of the use and distribution of electricity. EMFs refers to both the electric and magnetic fields that are created. The electric fields which relate to voltage levels may be shielded with common conductive materials but magnetic fields that are produced by electric current are more difficult and expensive to shield as they can pass through most building materials including concrete and stone.
These concerns fall into two categories; interference and health effects.
Interference Effects
- A large percentage of electrical and electronic equipment is sensitive to elevated EMF levels.
- Medical laboratories and hospitals are a major source of concern as EMF interference can have a catastrophic impact on the normal operation of medical devices and test equipment.
- Green ELMF Technology gives designers a more affordable solution that can be designed into a product, thus reducing the man-hours to design a product and requires less material therefore reducing manufacturing costs. ELMF technology designs can reduce 95% of the magnetic field.
Health Effects
- Within the scientific community, there is an ongoing debate regarding the links between EMFs and health risks. The scientific controversy resembles, in many ways, the past debate about the connection between smoking and cancer.
- There is a significant amount of growing research that shows that exposure to even low-level electromagnetic fields is harmful to human health.
- A major source of concern is power transmission lines, especially where they are located close to buildings. The State of California was the first to publish restrictions of the distance of these from schools and hospitals,
- Several industries (like welding), governmental and non-governmental organisation studies have warned of the dangers with EMF emissions.
There is increasing governmental regulation and public concern about EMFs. In the United States, the State of California has limited the building of new schools within high voltage power line right of ways. Local municipalities throughout the country have taken similar steps. The US National Council on Radiation Protection has recommended that new day-care centres, playgrounds, schools, houses, etc. should not be built where EMFs exceeds 2 MiliGauss
The World Health Organisation has called for precautionary approaches to exposure to power lines, electrical appliances and other EMF sources in the 50-60 Hz range. The new policy states that ambient EMFs near existing structures should be reduced “As Low As Reasonably Achievable” (ALARA policy). This definition of ALARA was most likely stated this way due to the large gap between the EMFs recommendation of 2-4 MilliGaus and the available technologies in the market.
Green ELMF technology represents a workable solution that significantly closes the gap between the requirements, and the means to achieve them. The technology is well within all of the existing regulatory
The Technology
The ELMF (Extremely Low Magnetic Field) technology allows, for the first time, to manufacture power cables that generate very low magnetic field. ELMF technology is based on EMF cancellation as opposed to protection. It opens the way to design a lighter and cheaper solution for the power distribution system. With Green ELMF Cable technology, the magnetic field is reduced by 95% in comparison the regular cables.
Important to emphasise that the technology is implemented in DC cables as well as with AC single and three phase cables. Moreover, the technology is functioning very effectively even when the phases are not equally
The Technological key features and benefits:
- Drastic reduction of the magnetic field (over 95%)
- Immunity – Drastically reduces influence of external magnetic fields
- Prevents serious hazard to human health caused by exposure to alternating magnetic fields.
In addition, there are few physical features that are of a great importance:
- Accelerated decay of the magnetic field
- Low self-Inductance that impose lower impedance that allows reduction in power losses
- Improved heat dissipation
- Improved current rating
- Using less conducting material
- Lighter than regular cable.
- Lower material cost in production.
Green technology and its key elements
Below are several key elements that are in use in conjunction for the above definition.
- Site design: Green design encourages the use of building sites that maximize passive solar heating and cooling, conserve natural resources such as trees and wildlife habitat, and minimize soil disturbance and erosion. Both location and design can encourage the use of alternate transportation methods such as transit, cycling and walking.
- Energy efficiency and renewable energy: Green design addresses building massing and orientation, and may incorporate high levels of insulation, capture of heating and cooling energy from geothermal or other natural sources, renewable energy installations (such as photovoltaics, wind turbines or solar hot water heating systems), energy efficient equipment and appliances, careful envelope design to harvest daylight, and the use of solar shading devices, daylight and occupancy sensors
- Conservation of materials and resources: Green design considers the environmental impacts of materials and products across their entire life cycle. It gives preference to those with low environmental impact and embodied energy in their extraction or manufacture; that are self-finished, non-toxic, multi-functional, durable, and easily salvaged and recycled at the end of a building’s service life
- Indoor environmental quality: Green design aims for high levels of natural ventilation and daylight in all occupied areas of the building. It also strives for high indoor air quality through construction protocols aimed at eliminating dust, airborne toxins and other contaminants, and through the specification of materials that contain no chemicals or compounds harmful to human health.
- Water quality, conservation and efficiency: Green design uses on-site mechanisms such as rainwater harvesting, water-conserving fixtures, waste water treatment and recycling, green roofs and controlled storm water discharge. This ensures water is used efficiently, and reduces the burden on municipal or other infrastructure to supply potable water, collect and discharge storm water, and treat and dispose of waste water
Is ELMF Technology can be defined as Green Technology?
- Site design: – Relevant
- Energy efficiency – Relevant
- Conservation of materials and resources – Relevant
- Indoor environmental quality– Relevant
- Water quality, conservation and efficiency – Irrelevant
Four out of the five key elements that were listed above are relevant to ELMF Technology that by no doubt can easily be classified as Green Technology.
