The present disclosure is directed to dielectric elastomeric composites that include a retainable processing membrane, an elastomer material, and an electrically conductive material. The elastomer layer may be partially imbibed into the retainable processing membrane. The retainable processing membrane may be porous. The retainable processing membrane is compacted in the transverse direction, machine direction, or in both directions prior to the application of an elastomer material and an electrically conductive material. The compaction of the retainable processing membrane may form structured folds or folded fibrils in the membrane, giving the retainable processing membrane a low modulus and flexibility. In some embodiments, the dielectric composites are positioned in a stacked configuration. Alternatively, the dielectric elastomeric composites may have a wound configuration. The dielectric composites have a total thickness less than about 170 .Math.m. The dielectric elastomeric composites may be used, for example, in dielectric elastomer actuators, sensors, and in energy harvesting.

One aspect of the invention provides a system including: a length of energy-dissipative tubing; a first sealing device coupled to a first end of the length of energy-dissipative tubing; and a second sealing device coupled to a second end of the length of energy-dissipative tubing. Exposure to one or more selected from the group consisting of: fault currents or lightning strikes at an exposure point along the length of energy-dissipative tubing will produce arcs at the exposure point and at least one of the first end and the second end.
