What is the XLPE cable?
What is the XLPE cable?
1.2.1 Description of XLPE cable XLPE is an acronym for cross linked polyethylene. XLPE is a thermosetting polymer meaning that the material (polyethylene (PE)) is cured under heat and in that process forms bonds in all directions forming a three dimensional matrix.
What is single core cable?
What is single core? Single core means that there is a single piece of metal wire, typically copper or aluminium, with insulation around it. The wire can be different gauges, as the size of the wire increases, the flexibility will generally decrease.
What is the size of XLPE cable?
Single Core XLPE Armoured Cables, Size: 1.5 Sq Mm
| Size | 1.5 sq mm |
|---|---|
| Insulation Material | XLPE |
| Packaging Type | Roll,Box |
| Rated Voltage | 26/35 KV |
What is the difference between single core and multicore cables?
While a single core cable has only one wire, a multicore industrial cable comes with two or more wires. Both types of wires are used in different electrical gadgets, appliances, and equipment.
What is the difference between single core and three core cable?
The selection of three-core and single-core power cables generally follows the following rules: three-core cables are selected under the condition of 6-10 kV voltage, and single-core cables are selected when the voltage level is 66 kV or above. However, 35 kV voltage grade cable has both three cores and single core.
Which cable is used in 11kV?
The cable is suitable for rated voltage 6/11kV according to IEC 60502-2….Technical Specification.
| Cable type | Cu/XLPE/SC/SWA/PVC | |
|---|---|---|
| According to regulation | BS 6622 | |
| Rated voltage (U) | (kV) | 11kV |
| Voltage to neutral (Uo) | (kV) | 6.35kV |
| Material of conductor | Copper |
Is XLPE cable flexible?
Application: Flexible single core cables, low smoke zero halogen, low toxic and corrosive emission, flame retardant; Suitble for mains. Independently tested and certified to IEC 60332-3 and BS6387.
Why do we use single-core cable?
Advantages of single-core cable: easy insulation between phases, not easy to occur short-circuit between phases; convenient cable transportation, easy laying; a long cable can be done, single-core cable with the same cross-section carrying capacity.
Is single-core or multicore wire better?
Cables with stranded conductors are easier to install because of their greater flexibility, and for some industrial applications a highly flexible conductor is necessary. Where cable route lengths are relatively short, a multi-core cable is generally cheaper and more convenient to install than single-core cable.
What is the height of HT pole 11kV?
11KV Electrical 2 Pole Structure
| Pole Material | Iron |
|---|---|
| Pole Height | 15-20 Feet |
| Surface Finish | Coated |
| Width | 3-5 Feet |
What does a XLPE cable stand for?
XLPE stands for cross-linked polyethylene. XLPE cable has a high chemical resistance and moisture resistance. XLPE = Cross-Linked Polyethelene There are actually two semi-conductive layers on high voltage cable. One is between the actual conductors and the XLPE.
What is the difference between PVC and XLPE cable?
Power Cable. Power cables are mainly used for power transmission and distribution purpose.
What is the meaning of XLPE electrical cables?
XLPE cable means cross linked polyethylene insulated aluminium conductor armoured cable. In XLPE cable stranded aluminium conductor is first screened in the form of a semi conducting extrusion which provides a smooth conductor surface and prevents formation of cavities at the surface of the conductor when the cable is subjected to bending.
What’s the characteristics of XLPE insulated cables?
Almost all cross-linkable polyethylene compounds (XLPE) for wire and cable applications are based on LDPE. XLPE-insulated cables have a rated maximum conductor temperature of 90 °C and an emergency rating up to 140 °C, depending on the standard used. They have a conductor short-circuit rating of 250 °C.
