1. Standard of XLPE  Power Cable: According to GB/T12706--2002( Equal to IEC60502)Also can do by standard of ASTM,BS,DIN and AS/NZS or other standards as request.

2. Rated Voltage of XLPEPower Cable:0.6/1KV

3. Construction of XLPE Power Cable:

Conductor: Copper or Aluminium

Insulation:XLPE

Inner sheath:PVC

Armoured:Galvanized steel tape,Galvanized steel wire

Outer Sheath:PVC

NO. of cable cross: 1 core(Single core),2cores(Double cores),3cores, 4cores(4 equal-section-area cores OR 3 equal-section-area+1 small section area neutral core),5cores(3 equal-section-area cores+2 small area neutral cores OR 4 equal-section-area +1 small area neutral cores).We provide armoured type and non-armored type for the cables stated above.

also can do according to the customer's request.

4. Characters of XLPE Power Cable:

a Max,rated  nominal operating temperature of XLPE insulated cable is 90°C

b.Laying  temperature of cable :in air 40°C,in soil 25°C.The cable is applied to fixed installation for rated voltage 3.5KVk for 5minutes,the insulation is not breakdown.

c.Max short-circuit temperature is 250°C,Max for 5 Sec.

d.For laying,single core,triangle laying for three cables.Depth of laying in direct:70cm,coefficient of thermal resistivity of soil:K.m/W.The cable can be laid without drop restriction,and environment temperature shall not be lower than 0°C

5. Description & Application of XLPE Power Cable:

 

TYPE		NAME	Main Application
CU core	AL core
YJV/YJY	YJLV/YJLY	XLPE insulated,PVC sheathed power cable	For laying indoor ,tunnel,canal and underground.Unable to bear external mechanical forces,but bear the traction force during laid
YJV22/YJV23	YJLV22/YJLV23	XLPE insulated,steel tape armoured,PVC sheathed power cable	For laying indoor ,tunnel,canal and underground.Able to bear external mechanical forces,but unable to bear large pulling force
YJV32/YJV33	YJLV32/YJLV33	XLPE insulated,thin steel wire armoured,PVC sheathed power cable	For laying in shaft,water underground will large difference of level.Able to bear external mechanical forces and moderate pulling force
YJV42/YJV43	YJLV42/YJLV43	XLPE insulated,thick steel wire armoured,PVC sheathed power cable	For laying in water and seabed.Able to bear positive pressure and pulling force

 

6. Advantage:

a. Excellent electric and mechanical characteristics

b. Best Resistance chemical corrosion and heat-aging,environment stress and flame-retardant

c. Simple in structure,Convenient to use

d. can be laid with no restriction of different level

 

7.Voltage test

Each drum of finished cable should withstand power frequeuency voltage 3.5kv or 5 minutes,the insulation is notbreakdown.
