A-2Y(L)2Y Laminated Sheath Telephone-outdoor Cable

Product introduction

01 Product application

These external subscriber telephone cables are installed as telecommunication connection cable for connecting the telephone extension to the telephone exchange or central offices and as well as for industrial plants. These subscriber connecting cables are suitable for laying in under ground, in cable ducts and cable conduits - and also for indoor-laying. Both sides of PE-copolymere coated aluminium type (L), which is spliced with the outer PE-sheath ensures a barrier against water vapour and diagonally water-proof. Black coloured PE-sheath is UV-resistant. The Polyethelene material (PE 2Y) is halogen-free.
