Cable Structure
- Conductor material: Annealed copper conductor according to IEC 60228, class 1 ( solid ), class 2 ( stranded ) or class 5 ( flexible ).
- XLPE core insulation: Cross linked polyethylene compound
- Core insulation color: As per customer request
- Outer sheath: Compound type of PVC/ ST2, or Low Density Polyethylene ( LDPE )
- Sheath color is normally black
- These Types of cables can also be manufactured with aluminium or aluminium alloy conductors, according to IEC 60228
Application
These types of cables are used for distribution of electrical energy for fixed installations in underground, cable ducts, power stations, indoors, in water and open air where mechanical damages are not expected.
In addition, XLPE insulation material has better mechanical, electrical, chemical and durability characteristics than PVC.
