Specific property for usage of 110kv~220kv xlpe high-voltage cable
1. Cable's conductor highest working temperature is allowed up to 90⺠c, and overload when meet an emergency is 130⺠c, when short circuit (in � 5 seconds) the highest temperature is 250⺠c
2. When installing or laying cable, the ambient temperature should be less than -20⺠c, and have to give a preheat to cable.
3. The minimum bending diameter(in follow the table):
Note: in form, d0 is a real test value to cable's outer diameter.
4. Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral-pressure at bent set ion) t=kã? core no. Ã? section (kg), in formula, the coefficient k value should be: the copper core get 7, the aluminum core get 4.
5. Allowed biggest lateral-press p, when cable is being bent
The single core cable is required pâ?¤ 500kg/m.
P=t/r (t is indicated axial traction force; r is indicated radius of bent-wheel), knowing from above formula, as the traction force is made up by length and weight of cable. So it lets p to applying requirement as above. Then the diameter of bent-wheel should be widened.
6. Cable laying is not being restricted by drop.
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. Color Codes : 2 Core Cables - Red, Black 3 Core Cables - Red, Yellow & Blue 3 Core Cables - Red, Yellow, Blue & Black (for Neutral) 4 Core Cables - Red, Yellow, Blue & Black 5 Core Cables - Red, Yellow, Blue, Black & Grey 6 Core Cables & above - Adjacent cores are blue for reference and yellow for direction in each lay Black outer sheath Specification : IS:7098 (Part-1) Packing : 500 / 1000 meters on drums

XLPE Insulated Power Cable Brief introduction to XLPE insulated Power Cable Since the 1960â??s, China has made rapid progress in its XLPE cable, replacing the oil paper insulated power cable, because of its outstanding electricity property , good overload , high voltage , large transmission capacity , light weight and laying without drop limit, vertical laying, convenient installation and operation maintenance and other strong points , XLPE cable can not only be widely used in 35 KV and below medium and Low voltage Cable scope, but also largely used in 66, 110 and 220 KV high voltage transmission lines. And , in some developed industrial countries 500 KV super-high voltage XLPE cables have been opened up.. Product Standard Huiyou Cablefocus on Various Power Cables, Our High Voltage XLPE Cables are very popular, and Our factory cab also design and produce some XLPE Insulated Power Cable for special requirements according to clientsâ?? demand. if you are interested in our products, please contact us as soon as possible.
