What is XLPE SWA?

The range of hard-wearing steel wire armour (SWA) and aluminium wire armour (AWA) XLPE insulated cables is manufactured in accordance with IEC 60502-1 and is designed for use in applications where there is a risk of mechanical stress and where protection is required against mechanical damage.

What is LSOH SWA?

LSOH (special low smoke zero halogen compound) Armour: single layer of galvanized steel wires applied spirally over the. bedding (SWA)

Why XLPE is used in cable?

Due to excellent thermal properties the current carrying capacity of XLPE cable is higher than that of conventional cable. XLPE insulation has higher dielectric strength compared to other conventional dielectrics used for cables resulting low dielectric loss.

Is XLPE thermosetting?

XLPE or Cross-linked polyethylene is a thermoset insulation material.

How is XLPE made?

Both linear polyethylene and XLPE tanks are made with heated resins to create a cured plastic….Compared to linear polyethylene, XLPE provides:

• 20 times the environmental stress crack resistance.
• 10 times the molecular weight.
• 3-5 times the impact and tensile strength.

What is CU XLPE?

Unarmoured – Concentric Conductor – IEC 60502-1. Application. Power cables for energy supply used in industry, distribution boards and power stations, for rated voltage up to 0.6/1kV. The concentric conductor can be used as neutral – protectiveearthed conductor, Suitable for.

Which is better XLPE or 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.

What are the XLPE insulated cables available with?

This range of XLPE insulated cables is available with a UV-stable PVC outersheath or with low smoke zero halogen (LSZH sheath) properties for applications where the emission of smoke and toxic fumes could create a serious threat to life and sensitive equipment in the event of fire. Need help?

What is the difference between LDPE and XLPE?

HDPE (High Density Polyethylene) has minimal branching of its’ polymer chains. Because it is denser it is more rigid and less permeable then the LDPE. It has a density of 0.941-0.965g/cm 3. XLPE (Crosslinked Polyethylene) is high density polyethylene which has covalent bonds between connecting its polymer chains.

What is the MDPE used for?

The MDPE provides protection from moisture ingress expanding the range of applications and making it suitable for use on motorways and areas where moisture may cause a problem for cable installation. For more information please consult a member of the Cleveland Cable Sales Team

What is the difference between LLDPE and MDPE?

This gives LLDPE higher tensile strength and higher impact and puncture resistance than the LDPE. It has a density of 0.91-0.94g/cm 3. MDPE (Medium Density Polyethylene) has a little less branching then the HDPE. It is less notch sensitive then HDPE and has better stress cracking resistance. It has a density range of 0.926 – 0.94 g/cm 3
