What does XLPE mean in cables?
What does XLPE mean in cables?
Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links. It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, and insulation for high tension (high voltage) electrical cables.
What is the XLPE insulation?
Cross-linked Polyethylene, also referred to as XLPE, is a form of insulation that is created through both heat and high pressure. One method of creating XLPE insulation is by irradiating the compound.
Which is better XLPE or PVC?
The main difference between the two is that XLPE can be used for both high and low tension applications. Its structure provides great resistance to abrasion, stress, and other wear and tear. PVC insulation cannot withstand as much pressure, meaning it is only suitable for low tension applications.
What is XLPE insulation stands in XLPE LV cables?
XLPE is the recognized abbreviation for cross-linked polyethylene. This and other cross-linked synthetic materials, of which EPR (ethylene propylene rubber) is a notable example, are being increasingly used as cable insulants for a wide range of voltages.
How is XLPE made?
Both linear polyethylene and XLPE tanks are made with heated resins to create a cured plastic. However, the differences in their production create very different polyethylenes with very different structural strength. Cross-linking is simply the formation of bonds between the polymer chains.
Can XLPE cable be buried?
Suitable for direct burial. Used for secondary distribution and underground service at 600 V or less. May be used in ducts or direct burial.
What is the difference between XLPE and EPR?
Like XLPE insulation, EPR insulation is suitable for many higher voltage applications and whilst its dielectric properties are not as good as those of XLPE it does have some important advantages over XLPE including extra flexibility, reduced thermal expansion, and low sensitivity to water treeing.
Is XLPE thermosetting?
Gross-linked polyethylene (XLPE) is a thermosetting compound which has better electrical properties than p.v.c. and is therefore used for medium- and high-voltage applications.
How can you tell PVC and XLPE cable?
So let’s see the differences in the following aspects:
- Maximum working temperature of conductor: PVC insulated Cable is 70 Centigrade, XLPE insulated Cable is 90 Centigrade.
- Maximum short (lasting less than 5 seconds) temperature: PVC insulated Cable is 160 Centigrade, XLPE insulated Cable is 250 Centigrade.
How do I know if my cable is XLPE?
You can usually tell by looking at the bedding around the insulation. XLPE has a softer, peelable appearance. Typically PVC is always black. XLPE is often white, grey or black.
What is XLPE material?
Cross-linked polyethylene (XLPE) is a thermosetting resin with three types of cross-linking: peroxide cross-linking, radiation cross-linking, and silane cross-linking. The polymer can be effectively recycled if only the cross-linking points are decomposed.
What do you mean by XLPE cable?
What do you mean by XLPE cable and what are its advantages over conventional cables? XLPE cable means cross linked polyethylene insulated aluminium conductor armoured cable.
Why choose all XLPE price?
All. xlpe price are carefully and precisely woven, braided, constructed and manufactured. The materials used are strong, flexible, conductive and above all-reliable. All products use safe and efficient materials you can examine with detailed product overviews and company profiles.
What are the mechanical properties of XLPE?
The mechanical properties of the XLPE are superior to many other insulations, offering greater tensile strength, elongation and impact resistances. The addition of carbon black can be used to further enhance hot deformation and cut through resistance. The XLPE insulation will not melt or drip,…
What are the benefits of XLPE insulation?
The XLPE insulation will not melt or drip, even at the temperatures of soldering irons, and it has increased flow resistance and improved ageing characteristics. Improved water-tree resistance is another benefit of XLPE insulation for LV cables and MV cables over PE insulations.
