For more information read through our outline to know more about Single Core XLPE Cable.
What is a Single Core XLPE cable?
Single Core XLPE cable is made of a single piece of metal conductors. The conductor is made of copper or aluminum. The copper and aluminum areas covered with cross-linked polyurethane insulation (XLPE).
The XLPE insulation is produced from polyethylene under high pressure with organic peroxide additives. The application of heat and pressure is used to effect cross-linking across-linking.
This then causes the individual molecular chain to link with one another. After linking the material is changed from thermoplastic to an elastic material.
An important advantage of XLPE as insulation for medium voltage XLPE cable and high voltage XLPE cable is their low dielectric loss.
The dielectric loss factor is about one decimal power lower than that of paper insulated cable. Since the dielectric constant is more favorable, the mutual capacitance of Single Core XLPE cable is lower. This reduces the charging current and earth-leakage currents in networks without the rigid star-point earthing.
You can use Single Core XLPE Cable in building services, cooling systems, domestic water piping, etc. You can also use it for offshore oil and gas transportation. Chemical and sewage transportation is also another use of Single Core XLPE Cable.
Make your project a success by using Single Core XLPE Cable from SSG. Our support team will ensure one year guarantee for every single order.
Chapter 2: How is Single Core XLPE cable manufactured?
We manufacture Single Core XLPE Cable at SSG. We manufacture both medium voltage and high voltage Single Core XLPE Cables.
We make use of the recent technology available in the field. Our plant uses an integrated high-performance extraction line. This extraction line we use it to minimize the risk of introducing external contamination. This line comprises of a triple layer crosshead and water-free curing.
It also has a cooling gas vulcanization process.
At first, the conductor is made through a metering capstan. We also refer to it as the line speed master point. To manufacture Single Core XLPE Cable we use the following components;
| A triple extruder crosshead |
| A vulcanizing tube |
| A monitoring unit |
| Haul-off caterpillars. |
The triple crosshead allows simultaneous extraction of the cable insulation. It also allows 2 semi-conducting screens with a high degree of smoothness.
All this is done to ensure no voids or external contaminants are introduced. To achieve precise temperatures at the cross-head we use multiple zone control temperatures.
At the vulcanization stage, we cure the triple extruded cable in an inert pressurized gas tube. After it’s heated to the required temperature material to enable cross-linking. We vary the curing temperature and time to achieve different cure percentages. Our customers might require different cure percentages.
In the monitoring unit, various functions of our integrated excursion line are monitored and controlled. Some of the functions include; line speed, curing tube temperatures among others. We have automated computers to ensure the production of quality ramps.
Some of the calculated parameters are present in our control unit. We have a closed-circuit TV system for ensuring the running of the cables.
Chapter 3: What is the structural design of Single Core XLPE Cable?
Our Single Core XLPE Cables design conforms to the international standards and those of IEC.
Our Single Core XLPE Cable is designed to have a circular single-core conductor. The conductor can either be made of stranded aluminum or copper which is compacted.
Special care should be taken to the conductors to ensure a smooth profile free from sharp juts. This jut may damage the insulation of the cable due to high electric stress.
We supply all medium voltage Single Core XLPE insulated Cable with extruded semi-conducting screens. This screen helps to protect the main solid XLPE insulation.
The conductor screen provides a smooth circular envelope around the conductor. This diminishes the concentration of the flux lines around the individual wires. It also diminishes electrical stress around the conductor.
Our insulating screen can either be a stripe or bonded. It depends on the order specifications you give us. You can use a bonded screen for high voltage XLPE cables.
An earthen envelope will be provided by the copper wires over the extruded insulation screen.
We pass the Single Core XLPE Cable through a testing program to ascertain its quality and performance.
We test them for;
– Partial discharge stability
– Its ability to withstand the impulse
– Moisture resistance
– Dielectric stress and overload current.

Chapter 8: What’s the difference between Single Core XLPE cable and multi Core XLPE cable?
The difference between a single-core and multi-core XLPE cable is seen in the applications. The single-core cable is made of one conductor either copper or aluminum. A multi-core cable contains more than one core in the cable, such as 3 core steel wire armoured cable, 4 core xlpe cable, 5 core power cables etc.
Multicore cables are used in electric applications while single-core cables are used for domestic purposes.
Single-core XLPE cables are very ambient and can handle high temperatures than multi-core XLPE cables.
Chapter 9: Why use lug and ferrule with Single Core XLPE Cable?
We fix Lugs and ferrule to your Single Core XLPE Cable by inserting the conductor into the tube of the device. Then we squeeze the barrel onto the conductor to form a secure mechanical and electrical joint.
To achieve that mechanical joint, the right lug or ferrule needs to be selected. The method of selection depends on the cable used and the area of application.
Some of the reasons we use ferrule and lug on your Single Core XLPE Cable include;
- Lugs have a thicker wall, improving the crimp and therefore better heat dissipation
- Lugs have no inspection window which aids the sealing of the cable end.
- Single Core XLPE Cable is a compacted cable meaning it has smaller core sizes than the standard cable.
- The internal diameters of lugs and ferrules are smaller than the standard lugs and ferrule. This help to fit the single-core size and prevent over crimping.
- Lug and Ferrule are used mainly in distribution networks to prevent moisture content.
