CABLE SEALING Russian patent published in 2005 - IPC

FIELD: flexible coatings and method for cable splice sealing.

SUBSTANCE: flexible coating for sealing cable splice without external heating has gel layer and supporting layer; its flexibility is sufficient to enable manually making gathers around cable-to-splice transition sections of smaller size in case there is gel at this transition for packing resulting seal. Supporting layer preferably made of low-density polyethylene ensures mechanical strength and facilitates coating procedure. Evaporation preventing layer preferably made of aluminum may be applied to supporting layer. Protective layer may be applied to evaporation preventing layer. Adhesion reducing material may be used at least on one end of gel layer facing supporting layer to provide for regulating coating placed on cable splicing sections. Flexible or rubber band may be wound on applied coating for gel compression.

EFFECT: provision for reusing seal obtained; enhanced sealing length.
