What is difference between PVC and XLPE?

Table of Contents

PVC stands for polyvinyl chloride insulation. 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.

Which is better XLPE or PVC cable?

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.

What does XLPE cable mean?

cross linked polyethylene
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.

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.

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 are the advantages of XLPE cables WRT PVC cables?

better impact, abrasion, corrosion resistance: safer than PVC cables against mechanical damage, abrasion and corrosion. easier jointing and termination: requires no special skills or equipment for jointing and termination.

Can XLPE be buried direct?

Common insulations used with direct burial cables are XLPE, PVC, and HMWPE. They are resistant to moisture, abrasion, and temperature changes.

Is XLPE sunlight resistant?

Applications and Features: Individual conductors are stranded aluminum alloy covered with a cross-linked polyethylene (XLPE) insulation and is rated for direct burial. The cable is sunlight resistant, RoHS compliant, passes -40°C cold bend.

Is XLPE 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.
