high voltage cable LDPE in tunnel N2XS(F)2Y

1 Application:

It is used to transmit and distribute power in power transmission and distribution system of 35kV or lower. It is
generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and
communication in complete replace of oil immersed paper insulated power cable and in partial replace of
PVC insulated power cable. Power cables for power networks, underground, outdoors and in cable ducting

2 Construction

Standards: BS6622, BS EN/IEC 60228,IEC60502.2

Conductor: Class 2 stranded plain copper conductor to BS EN 60228:2005 (previously BS6360)

Conductor screen: Semi-conducting material

Insulation: XLPE (Cross-Linked Polyethylene) Type GP8 to BS7655

Insulation Screen: Semi-conducting material

Metallic Screen: Individual and overall copper tape screen to BS6622

Filler: PET (Polyethylene Terephthalate) fibres

Separator: Binding tape

Bedding: PVC (Polyvinyl Chloride) Type TM1 to BS7655

Armoring:

Single Core: Aluminum Wire Armored (AWA)

MultiCore: Steel Wire Armored (SWA)

Sheath: PVC (Polyvinyl Chloride) Type TM1 to BS7655

Color: Red or Black

3 Using features:

1.Rated voltage: Uo/U:3.6/6kV, 6/10kV(11kV), 12/20kV(24kV), 19/33kV, 26/35kV(35kV).

2. No. of core: Single core or three cores.

3. The highest allowed operating temperature of conductor for long-term working is 90oC.
In short-circuit (Max. long-term is no more than 5 seconds). The highest temperature for
conductor is no more than 250℃.

4. D.C. resistance of the conductor complies with the stipulations of 3.6/6kV, 6/10kV(11kV),
12/20kV(24kV), 19/33kV, 26/35kV(35kV).

5. The environment temperature should be no lower than 0oC when lay. Otherwise it
should be preheated.

6. The cable is laid without horizontal drop limit.

7. Working Frequency Voltage Test: 3.5Uo/5min without puncture.

8. Partial Discharge Test: The discharge volume should be no more than 10pC under
1.73Uo for the cable.

9. Minimum Bending Radius

Single core - Fixed: 15 x overall diameter

3 core - Fixed: 12 x overall diameter

(Single core 12 x overall diameter and 3 core 10 x overall diameter where bands are
positioned adjacent to joint or terminations provided that the bending is carefully
controlled by the use of a former)

Note:

The single core armored cables are used for D.C. system only. If used for A.C. system,
the magnetic isolation should be applied on the steel armor wires of non-magnetical
materials should be used.

(1).What’s Yangguang cable main charactors ?

We can supply all of the cables including normally power cable , computer cable , control cable , equipment cable , etc. , because we own self factories and technology , can qualify all different customers’ requirement .

(2). What’s kind of standard do Yangguang cable take by ?

In China native market , we obey GB standard and all the export model we firstly must obey the IEC standard .Also we can supply the American ASTM standard , Germany VDE standard , French NFC standard , English BS standard , Australian and New Zealand AS/NZS standard.

(3)What’s the qualify system do Yangguang cable qualify ?

We firstly obey ISO9001 certificaten , and computer wire , electric wire we obey UL certificaten ,also some cable we obey the Rohs and CE certificate .

(4)When can I get the price?

We have strictly regulation , we must deal with customer’s quotation within 24 hours , if you have urgent requirement please call me and I will push the cost calculation accelerate forward.

(5).If I can get Yangguang cable authorization to join the international bidding ?

Yes, we can authorize the formula documents to help customers join in local bidding .

(6).What about the lead time for mass production?

Honestly, it depends on the order quantity and the season you place the order.The best record we keep is delivering 10 kilometers cable within a week. Generally speaking, we suggest that you start inquiry two months before the date you would like to get the products at your country.
