A typical Rubber sheath cable. The conductors are actually copper but are coated and look silver.

Tough Rubber Sheath cable normally consists of a black outer sheath of rubber with several conductors.
In the United States this is obsolete wiring, formerly used circa 1949-1969. Tough rubber sheath cable is in current use in the United Kingdom where greater mechanical toughness is required than PVC provides.
When it was introduced, Rubber sheath cables largely superseded lead-sheathed cables and plain conduit wiring, except where mechanical damage was a hazard.
