Product Details

1. Brief of XLPE insulation Power Cable

XLPE insulation power cable has a number of advantages over paper insulated and PVC insulated cable. XLPE cable has high electric strength, mechanical strength, high-aging resisting, environmental stress resisting anti-chemical corrosion, and simple construction, using convenient and higher operating of long term temperature. It can be laid with no drop restriction.

Various of flame-retardant and non-flame retardant XLPE cable can be manufactured with three technology (peroxide, silance and irradiation crossing-linking). The flame-retardant cable covers all kinds of low-smoke, low-halogen, low-smoke halogen free, and non-smoke non-halogenated and three classes of A, B, C.

Our XLPE cable can be manufactured according to company’s specification which is equivalent to IEC 60502, IEC 60332, IEC 60754. Some indexes are superior to above international standard.

Some of special XLPE cable can be manufactured according to the other standard required by customers.

XLPE cable having higher long term working temperature and greater current rating, at the same environment XLPE cable may be reduced size (nominal cross-section) 1 or 2 class in comparison with paper and PVC cable. This is not only improve the quality and propertied of products, but also reduce cable’s production costs.

2. Scope of XLPE cable

Type	No. of Core	Nominal Cross-section of conductor mm2
Cu(Al)/XLPE/PVC(PE) Cu(Al)/XLPE/ATA/PVC(PE) Cu(Al)/XLPE/AWAPVC(PE)	1	1.5-1000
Cu(Al)/XLPE/STA/PVC(PE) Cu(Al)/XLPE/SWA/PVC(PE)	2, 3, 4, 5	1.5-400
Cu(Al)/XLPE/STA/PVC(PE) Cu(Al)/XLPE/SWA/PVC(PE)	3+1, 4+1, 3+2	2.5-400

3. Cross-section area of neutral conductor
In 3+1 core and 3+2 cores should conform to specification of following table:

Nominal Cross-section	Main core	2.5	4	6	10	16	25	35	50
Nominal Cross-section	Neutral core	1.5	2.5	4	6	10	16	16	25

Nominal Cross-section	Main core	70	95	120	150	185	240	300	400
Nominal Cross-section	Neutral core	35	50	70	70	95	120	150	185

4. Main technical Characteristics of Cable
1) D.C .Resistance: Conductor resistance of finished cable per kilometer at 20oC is not more than the following:

Nominal Cross-section mm2	15	2.5	4	6	10	16	25
Cu core	12.1	7.41	4.61	3.08	1.83	1.15	0.727
Al core	18.1	12.1	7.41	4.61	3.08	1.91	1.20
Nominal Cross-section mm2	35	50	70	95	120	150	185
Cu core	0.524	0.387	0.268	0.193	0.153	0.124	0.0991
Al core	0.868	0.641	0.443	0.320	0.253	0.206	0.164
Nominal Cross-section mm2	240	300	400	500	630	800	1000
Cu core	0.0754	0.0601	0.0470	0.0366	0.0283	0.0221	0.0176

2) Voltage Test
Each drum of finished cable should withstand power frequency voltage 3.5kv for 5 minutes, the insulation is not breakdown.

3) Service conditions and parameters of cable
The cable is applied to fixed insulation for rated voltage 0.6/1kv of power transportation and distribution line.
Max. rated temperature of conductor nominal operating 90oC.
Short circuit: max. for 5 sec. 250oC.
The cable can be laid without drop retriction, and the environment temperature shall not be lower than 0oC.
