Copper Core XLPE insulated Power Cables

Copper Core XLPE insulated Power Cable


The cable is manufactured according to IEC60502.1, IEC 60502.2, AS/NZS 1429, AS/NZS 5000.1, BS 5437, BS 6622/7835, VDE 0276, ASTM, ABNT etc . It is suitable to be installed in the power line with rated voltage from (U0/U)0.6/1kV to 19/33kV for power transmission.

Copper Core XLPE insulated Power Cable - Cable Specification

1. Scope
The cables included in this catalog are manufactured and tested in accordance with IEC 60502.2.Whereas,CHANGFENG can supply XLPE insulated cables or according to customer's specification.

2. Construction and material
1) Conductors
Annealed copper, Hard aluminum stranded wires, Compacted circular and segmental compacted circular
shall comply with IEC 60228 class 2.
2) Conductor Screen
This will be an extruded layer of semi-conducting crosslinkable compound applied under simultaneous triple extrusion process over the conductor along with the insulation and the insulation screen. The triple extrusion is a single high precision operation that eliminates the possibility of any contamination between the layers which could create irregularities in the electrical field.

3) Insulation
This will be an extruded layer of XLPE or TR-XLPE applied over conductor screen under triple extrusion process along with conductor screen and insulation screen. PVC may be used for 1.8/3KV and 3.6/6KV cables.

4) Insulation Screen
Non-metallic part:This will be a layer of semi-conducting crosslinkable compound which will be applied by triple extrusion process over the insulation.
Metallic part:Metallic layer shall consist of one or more tapes or a concentric layer of wires or a combination of wires and tapes.

5) Laying-Up
In case of three core cables, the three cores are laid up with non-hygroscopic fillers like polypropylene(PP) fillers at interstices and a binder tape is applied with an overlap. These binder tapes can be of  PVC or Non-woven fabric or foamed Polyethylene.

6) Inner Covering/Separation sheath
Inner covering may be extruded or lapped. When the underlying metallic layer and the armour are of different materials, they shall be separated by an extruded sheath of PVC or Polyethylene or LSF as applicable.

7) Armouring
Armour shall be as per IEC 60502-2 of the following types:
a)       Round Wire Armour
b)       Double Tape Armour
Armour material shall be Galvanized steel for three core cables and Non-magnetic steel or Aluminium for single core cables. Armour of other material as per IEC 60502-2 can be provided upon request.

8) Over Sheath
An extruded layer is applied over the armour in case of armoured cables and over laid up cores in case of unarmoured cables. Outer sheath material can be either PVC, PE, HDPE or MDPE. Caledonian medium voltage cables are normally supplied with red PVC over sheaths complying with IEC 60502. Other colors may be provided to suit a range of installation considerations such as the effect of UV radiations and differing soil compositions. Anti-termite formulations can also be supplied in addition to graphite-coated over sheaths where on-site testing of the sheath is required.

3. Phase Identification
For 3 core cables, Red, Yellow and Blue coloured strips shall be applied under the metallic screen thoughout the length of the cable for phase identification.
For single core cables no phase identification shall be provided.
