    摘要: @ Telecommunications cable and method for its manufacture, the cable having two covering layers (28, 30) surrounding a core, each layer being a sheating or jacketing layer, and in which a water blocking layer (34) lies between the tow covering layers. The water blocking layer comprises a wrapping (36) of flexible and compressible powder pegnable material which is impregnated throughout its thickness with a powder (38) which contacts the outer surface of the inner layer and the inner surface of the outer layer. The powder is non-swellable and forms a viscous water blocking solution when in contact with water.
