Abstract
The invention features a shielded cable that has reduced susceptibility to system generated electromagnetic pulse effects. A two-part silicone rubber compound introduced to the conductive core and shield of the cable fills in all the voids and spaces between the wire leads and the shield braided strands, thus eliminating the deleterious pulse effect susceptibility.
Claims30
An electrical cable having a reduced susceptibility to system generated electromagnetic pulse effects, comprising:
- an insulated conductive wire core comprising at least one wire lead;
- a shield layer surrounding said conductive wire core;
- an insulative jacket surrounding said shield layer;
- and
- a cured, integrally formed, elastomeric, amorphous material mass disposed about said conductive wire core and substantially filling interstitial voids within said shield layer and between wire leads of said conductive wire core, whereby susceptibility to system generated electromagnetic pulses is substantially reduced.
An electrical cable having a reduced susceptibility to system generated electromagnetic pulse effects, comprising:
- an insulated conductive wire core comprising at least one wire lead;
- a shield layer surrounding said conductive wire core;
- an insulative jacket surrounding said shield layer;
- and
- a cured, integrally formed elastomeric, amorphous material comprising silicone rubber whose viscosity in its liquified, uncured state is in an approximate range of between 1.2 to 3.2.times.10.sup.6 centipoises, sufficient to allow it to flow under pressure about and within said wire core, wherein said cured silicone rubber becomes disposed about and integrally disposed within interstitial voids of said conductive wire core, and is further characterized by substantially filling voids within said shield layer and between wire leads, whereby susceptibility to system generated electromagnetic pulses is substantially reduced.
In an electrical cable including an insulated conductive wire core surrounded by a shield that is further surrounded by an insulative jacket, the improvement comprising:
- a cured, integrally formed, elastomeric, amorphous material mass disposed about and within said conductive core and said shield that substantially fills interstitial voids within said shield and within said conductive wire core, and between wires of said conductive wire core, whereby susceptibility to system generated electromagnetic pulses is substantially reduced.
