When I started with Post Office Telephones back in the 1960's I was taught that white or clear polythene sheathed underground cable should never be used above ground as it would be affected by the uV rays in sunlight.

Black polythene sheathed cable could be used above ground as it contained carbon which mitigated the uV affect.

PVC sheathed designed for internal use could be used out of doors so long as it wasn't exposed to direct sunlight.
