copper underground cable, copper wire armored cable
1. Scope
The cables are manufactured and tested in accordance with IEC60502. Whereas, Hengtian Special Cablecan supply XLPE insulation cables according to other recognized national and international standards or customer's specification .
2. Construction and Material
1) Conductor
Cbles are supplier normally class 2 of compacted cicular or circular standard conductors in copper or aluminum
2) Conductor Screening
All cable of rated voltage above 1.8/3kv are supplied with conductor screening which is non-etallic and consists of either semi-conducting tape or alayer of extruded semi-conducting compound,or acombination of the two.
3) Insulation
Insulation is a lay of extruded cross-linked polyethylene(XLPE).
4) Insulation Screening
For cable at rated voltage above 1.8/3kv ,insulation screening consists of a non-metallic semi-conducting part in combination with a metallic layer and consists of either semi-conducting tape or a layer of extruded semi-conducting compound.. The extruded insulation screen is normally free strippable(easy removable) type but can be provided with bonded one upon request
The metallic part is normally applied on the individual cores for rated voltage above 1.8/3kv and on the core assembly for rated voltage 1.8/3kv and consistes of plain annealed copper tape. or copper tape screen a layer of copper wire,a lead alloy or corrugated aluminum sheath can be provided upon request.
5) Inner Covering or Separation Sheath
(for armored cables)
A layer of PVC inner coveing is applied under the armor ,if there is no screen.
When the metallic screening and the armor are of different metals, an extruded separation sheath of PVC is provided in order to separate the different metals.
6) Metallic Armor
The armor, if required, consists of single layer of round wires or double tapes of galvanized steel or aluminum or other non-magnetic metals. Single core cables are normally armored with aluminum(other non-magnetic metals), because non-magnetic armor is essential for single core cable for use on A.C circuit .
7) Outer Sheath
All cable are normally provided with an extruded PVC out sheath, black colored(class ST2). Other materials can be available upon request,as PE , polyethylene,high flame retardant PVC and etc.
8) Core Identification
The multiple conductors are identified as according IEC60502 .
9) Cable Marking
The following information are indicated on the surface of the outer sheath:
----voltage rating, area for cable
----manufacturer's name
----year of manufacturer
----lengther for cable
