Copper conductor/XLPE insulation /special cold resistant jacket

According to the market demand, ZMS cable developed the popular cold resistant cables. In recent years, a large amount of these cables are sold to Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, other Central Asian countries and Mongolia market, has exported more than 50 million orders.


The cold resistant cable types ZMS can supply:

1.Cold resistant XLPE insulated medium voltage cable: YJV,YJV22,YJV32

2.Cold resistant XLPE or PVC insulated low voltage power cable: VV,VV22,VV32,YJV,YJV22,YJV32

3.Cold resistant control cable:KVV,KVV22,KVV32

4.Cold resistant PVC insulated electric wire: BV,BVR,BVV,RV


The level of ZMS cold resistant cable:


coldⅠ: cold temperature reached -60 ℃; 

cold Ⅱ:cold temperature reached -55 ℃;

cold Ⅲ, cold temperature reached -50 ℃; 

cold Ⅳ, cold temperature reached -40 ℃;


The Characteristic of ZMS cold resistant cable:


  • Long-term allowable working temperature of the cable conductor: PVC or polyethylene insulated cold resistant cable: cable                   long-term maximum allowable working temperature of conductor: 70 ℃,Short circuit (maximum duration of not more than 5s) The maximum temperature of the cable conductor does not exceed 160 ℃. XLPE insulated cold-resistant cable: long-term maximum allowable working temperature of able conductor : 90 ℃,Short circuit (maximum duration of not more than 5s) The maximum temperature of the cable conductor does not exceed 250 ℃. 

  • The lowest temperature of the cable can be applied: -60 ℃. The cable can be used for a long time in outdoor environment. The temperature is -60 ℃ ~ + 40 ℃. Allow the cables to be connected to and removed from the electrical equipment under the corresponding temperature-resistant temperature class. Be sure to bend slowly when connecting or disconnecting cables. The bending radius is 5 times of the cable diameter. There should have no impact on the cables during operation.

Product advantages and features Cold-resistant cable:

ZMS cold resistant cable has excellent cold resistance, can be installed in cold conditions in winter. Under the condition of ultra-low temperature, even under external force, the outer jacket of the cable still has good physical, mechanical, electrical and anti-aging properties and will not crack, thus greatly improving the safety and service life of the cable. Such general performance of the cable as electrical performance, mechanical performance in full compliance with national standards; its special performance indicators: the corresponding rated low temperature conditions (-40 ℃, -45 ℃, -50 ℃, -55 ℃ and -60 ℃) Low temperature winding test is not cracking, low temperature tensile test ,elongation is of 20% minimum, low temperature impact test does not crack.
