11kV 20kV 35kV Medium Voltage Power Cable Power Cable(under 35kv) :

Specifications

Distribution of electric energy at Medium Voltage, installed at air, underground ducts, raceways, direct buried or tray cables

Manufacturing Specifications: All the national and international specifications IEC, AS/NZS, BS, ICEA or any others. 

Conductor 
Copper or aluminum round compacted circular or segmental compacted circular according to the international specifications IEC 60228 or any customer's specification. 

Insulation 
The insulation material is made from XLPE. 
The conductor screen, insulation and insulation screen are extruded simultaneously in one process to ensure that they are free from all possibilities of voids between layers. 

Screening 
Copper tape ( or copper wire or lead sheath where required) shall be applied over insulation screen 

Bedding/Separation 
Polyethylene (PE) or Polyvinyl chloride (PVC). 
In case there is no requirement of armouring layer, the jacket shall be applied over screen. 

Armouring 
The protection the cable from mechanical stresses is achieved by the armouring of steel wires or steel tapes. 

If the cables are single core and are destined to be used in alternative current then the armoring is manufactured with non magnetic material ( Aluminum wires or tapes ) 

Jacket 
Polyethylene (PE) or Polyvinyl chloride (PVC). 

These cables are manufactured also with special properties in fire condition as flame retardant, low or zero smoke and toxic gas emission. In other case, they shall be manufactured to satisfy requirement of any termite attached.
