What is Vultex XLPEMedium voltage Electric Cable - 6,6kV to 33kV
1
Vultex is Aberdare’s registered brand name for MV power cable insulated with XLPE
Thermoplastic polyethylene:
XLPE Carbon-carbon cross-linking:
Polyethylene consists of long chain molecules, with some chain branching. These chains arenot interconnected and when subjected to rising temperatures, softening and eventualmelting of the polyethylene occurs.
However, by introducing suitable activators and catalysts in accurately measured ratios, three-dimensional links between adjacent chains are created to form “cross-linked” polyethylene(XLPE). This is thermally stable, with a much increased melting point and without adverseeffects on the electrical properties which remain outstanding.

Manufacturing of Vultex XLPE cableMedium voltage Electric Cable - 6,6kV to 33kV
The manufacturing techniques of this type of cable, such as the stranding of the conductor,the application of the semi-conductive layers, the insulation, the earth screen and the sheathare, in principle, not different from other plastic insulated cables. The laying-up of three coreassemblies is also similar to that of other plastic cables of comparable dimensions.Therefore good use can be made of the more than 40 years’ experience Aberdare have had inthis field in the manufacture of PVC and PE insulated cables.
Particular in the manufacture is the composition of the insulation material. Polyethylene plusadditives, including the cross-linking agent, are fed to extruders where the extruded conductorscreen and the integrally bonded dielectric and the core screen are vulcanised. A chemicalreaction occurs causing the cross-linking described earlier.
In the continuous catenary vulcanisation process, clean polyethylene and the semiconductingscreening formulations, fully compounded with their necessary additives including the cross-linking agent, are fed into extruders which form the three layers over the conductorconcentrically, with the necessary close adhesion between conductors, screen andinsulation. The composite application then passes into a catenary shaped vulcanising tubesealed to the main extruder head. The temperature in the tube is graded over 10 zonestypically from 520 °C to 20 °C using nitrogen gas at ±10 atmospheres pressure as the heattransfer medium (dry curing principle). This pressure prevents voiding in the insulation and atits screening interfaces, so that cavities are not developed, if the cable is exposed to bendingor other deformations. On leaving the vulcanising zone the cable is passed through a coolingzone and wound on a take up drum.
The Monosil process relies on slightly different chemistry and mechanical arrangements. Allthree extruders feed into a common triple head, and the cross-linking agents and catalysts aremetered in as fluids at the extruder throats. The insulation extruder disperses the cross-linkingagents before extruding the mix conventionally. The significant chemical in the cross-linkingformula is a functional vinyl silane which couples onto the polyethylene molecules to preparecross-linking sites for later activation.From the triple head, the core is extruded in a thermoplastic operation into an annealing andcooling trough of water graded from ± 90 °C to ambient temperature, and is then taken on to adrum for curing.
The curing process consists of exposing the drum of core to hot water (80-90 °C) or saturatedsteam for a pre-determined period. During this time the functional silane “bags” on thepolyethylene molecules are hydrolysed and condensed into Siloxane (-Si-O-Si) bridgesbetween adjacent carbon atoms.

TestingMedium voltage Electric Cable - 6,6kV to 33kV
On the basis of the many years experience in the field of electrical and physical tests on bothPVC and PE and later for XLPE insulated cables, internal testing standards have beenestablished, warranting a reliable product. Amongst other things, a great deal of researchhas been carried out on detecting and preventing partial discharges in the insulation.
The test equipment is sufficiently sensitive to detect and to plot energy discharges down to avalue of 1 pC.
All internal testing requirements comply with SANS 1339.
Among others the following tests were performed on cable and accessories, including thoseundertaken by the SABS:
• bending test with discharge detection• partial discharge test before and after heating• hot impulse voltage test• loading cycle test• mechanical properties and ageing test of the insulation and sheath
Vultex XLPE cables can be designed and tested to comply with all relevant foreignspecifications.
Each length of completed cable is subjected to the following check and tests before despatch.
• conductor resistance• dimensions and physical tests• voltage test of completed cable• partial discharge test of completed cable• sheath integrity test (if applicable)
On batches of finished cables further special (type) tests may be performed.
• bending test with discharge detection• partial discharge test before and after heating• mechanical properties test

Explanation of the tables:
Remarks
Note:
All dimensions are in line with SANS 1339, unless otherwise stated.
Conditions, under which the values mentioned in the tables apply, are:• One three-phase circuit, continuously fully loaded.• Single-core cables in trefoil formation touching and in flat formation respectively with
axial separation of 150 mm and regular transposition.• Conductor temperature 90°C • Ground temperature 25°C.• Depth of laying 800 mm • Soil thermal resistivity 1.2 K.m/W.• Ambient temperature 30°C in free air (shaded) • Solidly bonded at both ends.• Absence of other heat sources.
In certain types of soil, a conductor operating temperature of 90 °C for cables laid direct or inpipes may result in drying of the soil where a critical temperature of 55 °C is exceeded. Variousalternatives have been recommended, eg:
a) Restricting the sheath temperatures to 55 °C (by reducing conductor temperature);b) Rating the cable for fully dried out soil (thermal resistivity ±3 K.m/W) (both methods a & bcause substantial reductions in current ratings);c) Using a back-fill of stable thermal resistivity not exceeding 1.5 K.m/W and ratedaccordingly for a conductor temperature of 90 °C;d) Using the CIGRE method (Electra No. 104, January 1986, pages 11-22) of calculating arevised current rating assuming a partially dried out soil model.

Properties and applicationsMedium voltage Electric Cable - 6,6kV to 33kV
Due to the fact that Vultex XLPE insulation is resistant to high temperatures, it is also obviousthat higher temperatures are permissible in the cable.
For XLPE, continuous conductor temperatures up to 90 °C are permissible, whilst for somehours a temperature of 130 °C is permissible. In case of short-circuit the conductor canwithstand considerably higher temperature (up to 250 °C).
.
This important specific characteristic, in contrast with those generally applicable to
plastics, give XLPE insulated cables the following advantages:
• suitable for a sustained conductor temperature of 90 °C as a result of which a high current-carrying capacity is obtained
• suitable up to 125 hours/annum, (no event being longer than 8 hours continuously) at aconductor temperature of 130 °C so that emergency loads can be tolerated
• no drainage problems
• clean handling
• relatively low cost per installed kVA
• installation in buildings (vertical mounting)
• installation in routes with great difference in height
• installation in substations and power stations
The high current-carrying capacity can profitably be used in those cases where highertemperatures do not occur for too long or too often, viz. as a result of daily or yearly winterpeaks. Normally improved thermal dissipation during the night or colder weather improvesthe thermal stability of the installation.
Notwithstanding these claims for higher sustained current ratings, where higher than normalambient temperatures are obtained, (as in enclosed cable ducts or in ground which may dryout progressively under a sustained buried cable load) care should be taken when selectingthe conductor material and area. Refer to remarks (a) and (b) under General Characteristics.
In the current rating tables, the values in brackets next to the continuous current values,indicates the outer sheath temperature in °C, expected when the cable is fully loaded underthe stated conditions of installation.
In addition to the normal application as underground cables, the following specific
