| Types of Electromagnetic Waves |
Low Frequency (below 60 MHz)
The environment with low-frequency electromagnetic waves may influence people's nervous systems and
causes the diseases such as insomnia and melancholia, etc.
Low-frequency electromagnetic waves are not able to be isolated, only can be conducted. Even the best
electro-magnetic waves conductor in the USA or Germany technology is not able to provide effective
improvement on it. This is the reason why electric power substation, high-voltage electric case and signal
generating station are always labeled with warning marks. As it is no way to block low frequency
electromagnetic waves, the best way is keeping away from them.
The protection ability of our shield products to low-frequency electromagnetic waves is maximum 90%.
Mid Frequency (60 – 300 MHz)/High Frequency (300 – 900 MHz)
Mid to high-frequency electromagnetic waves can cause pathological changes to human cells as well heat-
destroy to human body.
Ultra High Frequency (above 900 MHz)
Our shield products were designed to provide the protection against the mid to ultra high-frequency
electromagnetic waves, the protection ability within the said range can reach 99.99%.
