The invention relates to a shielded module for electric cables meant for protecting the human being against the electromagnetic radiations produced by power supply cables of laboratory apparatuses, household appliances, t.v. sets, computers, microwave apparatuses, GSM antennas and the like. According to the invention, the module comprises seven overlapped layers, namely: a support layer (2) made of expanded polyvinyl, a layer (3) made of expanded polyvinyl wherein there is introduced an amount of 300 g/mof barium hexaferrite with a grain size of 0.1...0.3 mm, a layer (4) made of expanded polyvinyl wherein there are introduced 75g/mof aluminium grains with a grain size of 0.1...0.3 mm, a layer (5) made of expanded polyvinyl wherein there are introduced 75 g/mof copper grains with a grain size of 0.1...0.3 mm, a layer (6) made of expanded polyvinyl wherein there are introduced 300 g/mof SiOwith natural purity of over 98% and grain size of 0.1...0.3 mm, a layer (7) of biadhesive and a layer (8) of a foil for protecting the biadhesive, the assembly formed thereby being subjected to a process of magnetic charging. |
