Black filling mastic GZZ-2

    Black tapes are applied to the cable connection in a stretched form (up to 30%) overlapping one another. As a result, the layers of the tape stick together, forming a homogeneous mass similar to cold vulcanization technology. It is used when sealing the "coupling neck" - it protects against the penetration of moisture in the place of the cut of the armor on the cable sheath in cable couplings. It is used in couplings where the grounding wire is connected in cable couplings. 2 tapes of sealant are included
