Belted construction in which Screen construction (H type) in Screened SL construction (HSL
insulation in the form of which each core has its own type) which, in addition to
common belt, in addition to insulation and screen possessing its own insulation
core insulation, is employed and screen also has a separate
lead sheath for each core as
against a common lead sheath
in the other two types
