WHAT IS XLPE?

Cross linked polyethylene is produced from polyethylene under high pressure with organic peroxides as additives.The application of heat and pressure is used to effect the cross linking. This causes the individual molecular chains to link with one another which in turn causes the material

to change from a thermoplastic to an elastic material.

An important advantage of XLPE as insulation for 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.Since the dielectric constant is also more favourable the mutual capacitance of XLPE cables is also lower,thus reducing the charging currents and earth-leakage currents in networks without the rigid star-point earthing.

 

CHARACTERISTICS AND ADVANTAGES OF XLPE: 

1.Excellent Electrical and Physical Properties:

XLPE cable constitutes the best cable for transmission and distribution lines because of its excellent electrical and physical properties.

2.Capability of Carrying Large Currents:

The excellent resistance to thermal deformation and the excellent aging property of XLPE cable permit it to carry large current under normal (90°C), emergency (130°C) or short circuit (250°C) conditions.

3. Ease of Installation

XLPE cable withstands smaller radius bending and lighter in weight, allowing for easy and reliable installation. Furthermore,the splicing and terminating methods for XLPE cable are simpler in comparision with other kinds of cables.

4. Free from Height Limitation and Maintenance

XLPE cable can be installed anywhere without special consideration of the route profile (high limitations) since it does not contain oil and thus is free from failures due to oil migration in oil-filled cables.

5.No Metallic Sheath Required

XLPE cable does not generally demand a metallic sheath. Thus it is free from the failures peculiar to metallic-sheathed cables, such as corrosion and fatigue.

 

PROCESS OF XLPE CABLES:

Although it has been verified that XLPE cables can be applied with a conductor temperature of 130ºC for emergency overload conditions, it must be understood that the erecting and laying conditions necessary to allow for those temperatures must be accurately carried out and controlled during installation in order to restrict thermomechanical problems. To be realistic, emergency condition should be confined to 110°C at conductor with the balance of 20ºC premeditated as a safety margin to cope with some concerns in the laying conditions.

Subsequent to the constant use of XLPE for midium and high voltages for many years in the past, our plant has extensive field test result which evidently witness that XLPE insulated cables are of excellent quality particularly in respect of :

·partial discharges with standability

·impulse test with standability

·moisture resistance

·overload current-test under dielectric stress and thermic cycles
