ABSTRACT:
A termination closure (20) for buried or underground service cable splice locations includes molded stepped end blocks (40--40) and a cover (100) which comprises a sheet adapted to be wrapped about service cables (28--28) having conductors (26--26) which are spliced to conductors (24--24) of a distribution cable (22) and secured by clamps. The closure also includes a pivotally mounted organizer (80) which is perforated to allow an encapsulant to be flowed therethrough into engagement with an enclosing bladder (90). The organizer effectively isolates splice connections from the distribution cable core (23). The bladder which is wrapped about the organizer is adapted to receive encapsulant from a tube which extends through one of the end blocks to allow it to be flowed into the interstices among the spliced conductors and distribution cable core. Air in the closure is pushed from one end of the closure and evacuated through a relief valve (59) in the other end block. The relief valve is arranged so that an indicator thereof is not moved outwardly to provide a visual indication until the closure has been filled properly.
