Using Festures of Power Cable:
1.Rated Voltage 0.6/1kV PVC Insulation Power Cable :
The long-term working temperature of cable conductor should be not more than 70°C.
While short-circuit the highest working temperature of cable conductor should be not more than 160°C(5 seconds maximum duration);
The minimum bending radius for laying cable(D is diameter):single core unarmoured cable shoule be 20D,multi-core unarmoured cable shoule be 15D,single core armoured cable shoule be 15D,multi-core armoured cable should be 12D;
The environment temperature for laying cable should be not less than 0°C.

2. Rated Voltage 0.6/1kV XLPE Insulation Power Cable / Rated Voltage 3.6/6~26/35kV XLPE Insulation Power Cable :
The long-term working temperature of cable conductor should be not more than 90°C.
While short-circuit the highest working temperature of cable conductor should be not more than 250°C(5 seconds maximum duration);

3. Rated Voltage 0.6/1kV and Freqency Inverter Control System Power Cable :
Designed with fully symmetric space structure,cable has excellent electromagnetic compatibility;
Low and uniform positive sequence and zero-sequence impedances have greatly improved power quality compared with ordinary four-core cable;
The environment temperature for laying cable;PVC and XLPE insulation is 0°C;
The maximum working temperature of cable;PVC insulation is 70°C,XLPE insulation is 90°C;
Low-smoke halogen-free flame retardant cable:PH value of burning gas ≥4.3,conductivity≤10us/mm,minimum light transmittance shall not be less than 60% while product burning;
The minimum bending radius for laying cable is 12D(D is diameter).

4. Copper Clad Aluminum Power Cable
Maximum temperature of cable of cable conductors during normal operation and short-circuit (5 seconds maximum duration): PVC insulation is 70oC, the highest temperature should be not more than 160oC while short circuit; XLPE insulation is 90oC,the highest temperature should be not more than 250oC while short circuit;
The minimum bending radius for laying cable (D is diameter):single core unarmoured is 20D,three-core unarmoured is 15D, single core armoured is 15D,three-core armoured is 12D;
The environmental remperature for laying cable should not less than 0oC

Notes:1.Ratproof,termite-proof,moisture-proof and other special requiremments cables are available.
2.The single core armoured cable are used for DC system only.As for AC system,non-megnetical materials shoule be used,its corresponding code is 62,63,72,73;
3.It is not recommended AL-core fire retardent cable.When there is a fire,flame temperatures may reach 700°C above due to the meilting point of aluminium is only 660°C,the conductor may be fused;
4.Flame retaradant/fire resistant power cable are available:Representation method of flame retardant grade is the "Z" followed by"A","B","C",such as the "ZA","ZB","ZC".When "ZR" expressed,generally considered to be "C" class of flame retardant.Flame retardant level representation is "ZN" middle "A","B","C",such as the "ZA","ZB","ZC".While using "NH" expressed,it generally considered to be "ZCN".For example;

Notes:1.Flexible power cable is available.Plus "R" after sheath material types.For example,"VVR" refers to cooper core PVC insulation PVC sheath flexible power cable;
2.Hear-resistant 90°C and 105°C power cable are available,Plus "-90" "-105" after the type.For example,VV-105 refers to copper core heat-resistant 105°C PVC insulation and sheath power cable,and the highest temperature of cable conductor is 105°C.
