1.Application
PVC insulated power cable has excellent electrical properties and chemical stability, it is suitable for fixed laying in power transmission and distribution lines with AC 50Hz and rated voltage below 1KV.
2.Standard: IEC 60502, IEC 60228, IEC 60332
3.Using Features
The long-term working temperature of conductor should be not more than 70oC ;
The maximum working temperature of conductor should be not more than 160oC while short-circuit.
The minimum bending radius of cable laying (D is diameter): single core unarmoured cable is 20D, multi-core unarmoured cable is 15D, single core armoured cable is 15D, multi-core armoured cable is 12D.
The environment temperature of cable laying should be not less than 0oC.
Applications:
Low Smoke Halogen-Free heavy duty 2.5mm electric Wire can produce little smoke and innocuous gas without halogen when combustion.It can extremely reduce the damage to the instruments and body as the fire occurred .So, it was widely used in high-rise building, hospital,large-sized library, gymnasium, disaster prevention command and dispatchbuilding, station, civil airfield, passenger waiting room,emphases cultural relic, subway, underground shop or the crowded public concourses.
Voltage: 35KV and below.
Standards:IEC6052:2004 IEC60050:1984 IEC60227:1997 IEC60332:2000
Using Features:
The highest working temperature of cable conductor:XLPE insulation is 90oC;irradiation cross-linked polyolefin insulation is 105oC 125oC ; |
The environment temperature for laying cable should be not less than0oC |
For Low-smoke Halogen-free Cable:the PH of the cable's combustion gas should be 4.3 or higher; the conductivity is 10us/mm or lower, the lowest light transmittance of the fished cable should be not less than 60% while burning. |
