What is XLPE insulation?
XLPE or Cross-linked polyethylene is a thermoset insulation material. Crosslinking polymers is a process which changes the molecular structure of the polymer chains so that they are more tightly bound together and this crosslinking is done either by chemical means or physical means.
What is XLPE used for?
XLPE cable can be used for plumbing, mining, and various electrical applications. Cross-linked polyethylene cables can also be found across the chemical industry and within the commercial and residential heating industry.
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.
What is the meaning of XLPE cable?
cross linked polyethylene
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. Within this XLPE matrix there is space between the individual molecules.
Why XLPE is better than PVC?
XLPE provides greater tensile strength, elongation and impact resistances compared with PVC. This cross linking process also enhances the material’s resistance to oil and chemicals even at elevated temperature; this makes XLPE a popular pick as insulation for LSZH Flame Retardant or Fire Resistant cables.
Is XLPE waterproof?
In order to prevent the penetration of moisture and also to extend the duration of life, the XLPE insulated medium voltage cables are designed with longitudinally waterproof shielding including an additional swell tape and PE outer jacket.
Which insulation is better XLPE or PVC?
What type of wire is XLPE?
stranded copper conductor wire
XLPE wire is a single-stranded copper conductor wire that is insulated with hydronic tubing made of cross-linked polyethylene plastic (XLPE). The XLPE insulation has a three-dimensional bond within the plastic. The insulation is a thermoset, zero halogen insulation that provides flame retardant properties.
What is the temperature of XLPE cable?
The project determined that the XLPE component of an XLPE transmission system can be operated at up to 130 °C conductor temperature without suffering mechanical degradation.
Which insulation is better PVC or XLPE?
Which is better XLPE or PVC?
Is XLPE sunlight resistant?
XLPE/AIA/PVC 600 Volt Power Type MC Cables provide an excellent crush resistance and a cost effective alternative to installations in conduit in commercial, industrial and utility applications as well as being Sunlight, Oil and Chemical resistant.
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.
Is XLPE cable Armoured?
XLPE cable means cross linked polyethylene insulated aluminium conductor armoured cable.
How many types of XLPE cable are there?
Designation according to type of insulation
| nomenclature | Cable type |
|---|---|
| R | Crosslinked polyethylene (XLPE) |
| X | Cross-linked polyethylene (XLPE) |
| Z1 | Halogen-free thermoplastic polyolefin |
| Z | Halogen-free thermosetting elastomer |
Is XLPE fire retardant?
In such applications, flame-retardant additives are introduced in a fully formulated composition. Common applications requiring flame-retardant (FR) XLPE include building and construction, military, shipboard and other transportation, electronics and appliances.
Can XLPE be direct buried?
Excellent heat, ozone, oil and chemical resistance. Resistant to tear and abrasion. Suitable for direct burial.
Is XLPE heat resistant?
XLPE – Cross-linked polyethylene which is an upgraded version of PE has got good fire resistance properties and can withstand up to 90°C when compared with PE’s 75°C.
