Brief Introduction
PVC/XLPE power cable is used to transmit and distribute power in power transmission and distribution system of 35kV or lower. It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable and in partial replace of PVC insulated power cable.
Standard
The products can be produced according to our factory specification which is equivalent to the standard IEC60502. The factory can also design and manufacture special power cable according to the other standards required by the customers.
Properties of PVC Power Cable
1. The long-time permissible working temperature of cable conductive core is not more than 70 degrees.
2. During short circuit (max permanent time is not more than 5 seconds), the max temperature of cable conductor is not more than 165° C.
3. The difference level of laying cable is not restricted. When laying the cable, ambient temperature is not lower than 0° C.
4. They have good chemical stability, and properties of acid resistance, alkali resistance, salt resistance, oil resistance, solvent resistance and flame resistance.
Properties of XLPE Power Cable
1. The highest allowed operating temperature of conductor for long-term working is 90 degrees.
2. In short circuit (Max long term is no more than 5 seconds). The highest temperature for conductor is no more than 250 degrees.
3. The cable is laid without horizontal drop limit. The environment temperature should be no lower than 0 when lay. Otherwise it should be preheated.
4. Excellent electrical performance, resistance to chemical corrosion.
5. Can stand advisable traction when laid. Can stand traction from Outside. Left low smoke halogen-free after burned. Retard the burning of the cable.

The cable design conforms to the requirements of national standard GB/T12706-2008 and IEC60502 recommended by international Electrotechnical Commission. The normal operating temperature of the conductor of polyvinyl and XLPE insulated cable is 70â?? and 90â?? ,Xlpe cable not only has excellent electrical performance, high working temperature, large transmission capacity, but also has the advantages of simple structure, small outer diameter, light weight, easy installation and use, and unrestricted laying drop. It is widely used in industrial and mining enterprises and urban power grid.
6-35kv medium vollage power cable selection with cross-linked polyethylene insulation and plastic Sheath material, insulation layer USES the three co-extrusion technology, full automatic Change control. Such products, aging resistance, corrosion resistance, environmental stress not only electricity Gas properties and good mechanical properties, and has a simple structure and outer diameter Small, light weight, easy to use and elaborate divide not restricted, Public places such as crowed, place closed space.
Application :- The XLPE (Cross Link Poly Ethylene) Power Cables are used under ground as well as over head transmission of power in power plants, industries, projects and all other electrical installations. Features :- Manufactured from bright annealed 99.97% pure bare copper & aluminum conductors. These cables are insulated with XLPE compound. Taped/Extruded inner sheath. Round steel wire / flat galvanised steel grip armoured. The outer sheaths can be PVC, HR PVC, FRLS or FR depending upon the application and requirement. Technical Advantage of XLPE Insulation :- Higher current rating, higher short circuit rating (approx 1.2 times that of PVC), thermosetting in nature, higher insulation resistance (1000 times more than PVC cables), higher moisture resistance, better resistance to surge currents, low dielectric losses, better resistance to chemicals and corrosion, longer service life. Comparatively higher cable operating temperature 90�°C and short circuit temperature 250�°C. Technical Data :- Working Voltage : Up to 1100 V Temperature Range : -15�°C to +90�°C Power Cable Sizes : 1.50 Sq. mm to 400.00 Sq. mm in 2, 3, 3 Copper Control Cable Sizes : 1.50 Sq. mm, 2.50 Sq. mm up to 24 cores.
