Power Cable Rated voltage 1kV（1.2kV）and3kV(3.6kV)

Product Description:

Rated  voltage 1kV（1.2kV）and3kV(3.6kV)

PVC insulated Flame retardant and Fire  resistant cables

XLPE insulated Flame retardant and Fire  resistant cables

Brief  introduction

PVC insulated Flame retardant  and Fire resistant Power cables are fixed laid in the circuit with frequency  50Hz and voltage upto 3.6/6kV.

XLPE  insulated Flame retardant and Fire resistant Power cables are fixed laid in the  circuit with frequency 50Hz and voltage upto  3.6/6kV.

We can  produce Flame retardant and Fire resistant with PVC or XLPE insulated power  cables according to standard GB/T19666,Grade A, B,C or  D.

Rated  Voltage ：0..6/6kV、3.6/6kV。

Conductor of cables can be  Copper and Aluminum.The cables can be single core,two cores,three cores,four  cores(including three main cores and neutral).five cores (including three main  cores and neutral and one earthing core,Four main cores and one  neutral).The cables can be with armour and  without armour.

We can produce cables with PVC  outer sheath,Flame retardant PVC outer sheath or with fire resistant  insulation.The cables are produced according to GB/T12706(eqvIEC60502) and  GB/T18380-2001(eqv IEC60332),or GB/T19216(IEC60311) and or the BS,DIN, or other  international standards. And we also design and produce cables according to the  requirement of our clients

Application

1、           Long term working  temperature for the cable with PVC insulated is 70℃；

Long term working temperature for the cable with XLPE  insulated is 90℃

2、           Short circuit  temperature

For PVC insulated cable ,the highest  conductor temperature is not more than160℃.(lasting time not  over 5 seconds)。

 For XLPE insulated cable ,the highest conductor  temperature is not more than250℃.(lasting time not  over 5 seconds).

3、           Laying temperature not less than  0℃ and  the drop height is out of consideration。

4、           The cable with chemical stability,anti  acid,anti alkali, anti oil,anti organic solvent,not easy to be  burning。

5、           Easy for installation,easy bending and  light

6、           Bending ratio：

Rated voltage  6kV(Um=7.2) and 35kV(Um=40.5)

XLPE  insulated power cable

Product  standard

XLPE  insulated cable has good electrical and pysical properties, resistant to aging,  resistant to the environment stress and chemical corrosion operation, with the  characteristics of simple structure, easy to use, no drop-height restricton when  laying,higher long-term working temerature (90℃).

Table of the voltage,cores  and cross-section

The  cable with Category A rated voltage is used in the situation requiring not over  1 min.of grounding fault lasting time.For the cable with Category B rated  voltage, the grounding fault lasting time normally is not over 1 hour, max.  lasting time is not over 8 hours, annual ground fault lasting time altogether  should not be over 125 hours, Category C includes all the system expect Category  A and B.
