Abstract
A preferred embodiment of the cable of the present invention incorporates a core, an outer jacket surrounding the core, and a super-absorbent foam disposed between the core and the outer jacket as well as inside the core. The super-absorbent foam comprises a polyurethane or similar type foam loaded with super-absorbent polymers (SAPs) which exhibit both water-blocking and flame-retarding characteristics. Additionally, the foam preferably is provided with a moisture content of greater than approximately 0 percent, by weight, thereby improving the flame-retarding characteristics of the foam.
