Abstract
A forming paste, for example in the form of a sprayable putty, wherein the composition substantially consists of a binder and an electrically conductive component in such an amount that a signal attenuation of at least −30 dB or higher takes place in the range of 30 MHz-1 Ghz in the electromagnetic interference measurement according to the EMC IEC 11.9.1 standard.
Claims14
Bushing device (1) for at least one cable (3) to provide protection against electromagnetic overtension and/or interference, said busing device (1) having a housing (2) in which the cable (3) is led through, said cable (3) being partially stripped of its insulation sheath along a portion (4) of its length, wherein said portion (4) is embedded with an electrically conductive forming paste (5) so as to place said cable (3) into electrically conductive contact via the forming paste (5) with the housing (2), wherein the composition of the forming paste (5) comprises a binder and an electrically conductive component in such an amount that a signal attenuation of at least −30 dB or higher takes place in the range of 30 MHz-1 Ghz in the electromagnetic interference measurement according to the EMC IEC 11.9.1 standard.
Method for protecting at least one cable (3) led through a housing (2) of a bushing device (1) against electromagnetic overtension and/or interference, comprising the steps of:
- partially stripping said cable (3) of its insulation sheath along a portion (4) of its length;
- embedding said portion (4) with an electrically conductive forming paste (5) so as to place said cable (3) into electrically conductive contact via the forming paste (5) with the housing (2), wherein the forming paste (5) comprises a binder and an electrically conductive component in such an amount that a signal attenuation of at least −30 dB or higher takes place in the range of 30 MHz-1 Ghz in the electromagnetic interference measurement according to the EMC IEC 11.9.1 standard.
