Claim 10

A service entrance cable comprising: a. a plurality of electrically insulated electrical conductor strands and a neutral conductor, grouped to constitute a cable core; b. a complete barrier layer about said cable core, said barrier layer being at least one helical wrap of a composite tape of open weave glass fiber cloth partly embedded in a coating of uncured, flame resistant synthetic rubber; said complete barrier layer comprising two complete helical wraps of said composite tape, applied one over the other, with lateral edges in each wrap abutting to form butt joints, the butt joint of the outer of said wraps of composite tape being centered upon the inner of said wraps of composite tape; and c. a jacket of electrical material extruded in place about said barrier layer and being fused thereto.

Claim 11

A service entrance cable comprising: a. a plurality of electrically insulated electrical conductor strands and a neutral conductor, grouped to constitute a cable core; b. a complete barrier layer about said cable core, said barrier layer being at least one helical wrap of a composite tape of open weave glass fiber cloth partly embedded in a coating of uncured, flame resistant synthetic rubber; said complete barrier layer comprising two complete helical wraps of said composite tape, applied one over the other, with lateral edges in each wrap abutting to form butt joints, the butt joint of the outer of said wraps of composite tape being centered upon the inner of said wraps of composite tape; and c. a jacket of electrical material extruded in place about said barrier layer and being fused thereto.

Claim 12

The service entrance cable of claim 8 wherein the said coating of the two wraps of composite tape face one another.
