Sheat-type Conductors

These extremely compact conductors are characterized by the complete lack of hollow space due to an high strength steel core covered by extrusion of a penetrating annealed Aluminium sheat. This allows:

Sheat-type conductors are especially suitable to replace small AAC, AAAC and ACSR conductors in short spans lengths.
