What is XLPE PVC cable?
XLPE is cross linked polyethylene material and PVC stands for polyvinyl chloride insulation. Both XLPE cable and PVC cable are the most popular cables. While sometimes we need to make a right choice between the two insulated cables especially when we need to choose a kind of Low voltage (0.6/1kv) Cables in a project.
What is the XLPE cable?
XLPE cable means cross linked polyethylene insulated aluminium conductor armoured cable. Pure polyethylene is a thermoplastic material i.e. it becomes soft and plastic on heating and hard on cooling. Pure polyethylene is converted into thermosetting XLPE i.e. it sets permanently when heated.
Why XLPE is used in cable?
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.
What are the specific advantages of PVC and XLPE insulation?
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.
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.
What is the difference between PVC and XLPE cable?
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.
How can you tell the difference between PVC and 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.
How do I know if my cable is XLPE?
What is the difference between XLPE and XLPO?
XLPO can withstand temperatures only upto 120°C Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links. XLPE can withstand temperatures only upto 90 °C. Due to higher with stand temperature, Life of XLPO insulated cable is more.
What is PVC PVC cable?
PVC (Polyvinyl chloride) is widely used in electrical cable construction for insulation, bedding and sheathing. Cable with a PVC insulation or sheathing is flame retardant, which is an important consideration for electric cables in most applications.
What is the difference between XLP and XLPE?
CROSS-LINKED POLYETHYLENE(XLP) is a material which has greater resistance to environmental stress cracking, cut-through, ozone, solvents and soldering than either low or high density polyethylene. Sometimes designated as XLPE. Can be cross-linked either chemically or irradiated.
Which is better XLPE or PVC cable insulation?
An important advantage of XLPE as insulation for medium and high voltage cables is their low dielectric loss. The dielectric loss factor is about one decimal power lower than that of paper insulated cables and about two decimal powers lower than that of PVC- insulated cables.
What are the international standards for XLPE cable?
The design of XLPE cables conform to international standards and are similar to those in IEC 60502 and IEC 60840. XLPE insulated cable for medium and high voltages have, in general, circular conductors and only single core construction is adopted for the latter.
What kind of extrusion line is XLPE cable?
In the manufacture of medium and high voltage XLPE cable, our plant uses the latest technology available in the fieldby using an integrated high performance extrusion line which consists of a triple-layer crosshead and a water-free Completely Dry Curing and Cooling (CDCC) gas-vulcanizing process.
How many cores are in an XLPE booklet?
The sizes below are the most commonly used XLPE booklet, non-booklet and mains armoured cables: Multi-core auxiliary control cables are also available with seven cores to 48 cores.
