The effect of temperature cycling on mechanical and electrical properties of syndiotactic polypropylene

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1375207

Polypropylenes (PP) are a candidate to replace cross-linked polyethylene (XLPE) in medium voltage cables. This is due to its recyclability and potentially lower energy consumption during production. To prove to be an alternative, the PPs must meet the same requirements as for XLPE. The maximum servi...

Temperature and Electric Field Dependence of the Time Domain Dielectric Response of a Medium Voltage Cable Joint Stress Control Sleeve

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258143

...dependence of the time domain dielectric response of a virgin stress control sleeve commonly used in heat shrink joints has been studied. The result show that the conductivity of the stress control sleeve is strongly temperature dependent and that space charge phenomenon build up even at average fie...

Determine the Compatibility between Electrical Insulation Fluids and Solid Materials Using a Micro-calorimeter

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1354038

Compatibility between solid and liquid electrical insulation materials has been studied using an isothermal microcalorimeter. This work compares the micro-calorimeter measurements with a simple volume and mass increase for the solid material also capable of indicating incompatibility and compatibili...

Wet designs for HV submarine power cables

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258112

This paper presents an evaluation and results from a water aging test performed at 10 kV/mm - 500 Hz of a HV 52 kV XLPE core. Water permeation tests and associated modelling have been performed on power cores with a PE-sheath only and a non-impervious water barrier to evaluate the effect of the “sem...

On-site Condition Assessment of XLPE MV Cable Joints by Using an Insulation Tester

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258126

In this paper, on-site time domain dielectric response measurements have been performed once a month on medium voltage XLPE cable links with heat shrink joints using a conventional 5 kV DC insulation tester. The main purpose of this work has been to examine the reproducibility of the measured curren...

Effect of static mechanical strain on the DC conductivity of extruded cross-linked polyethylene cable insulation

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258129

DC current measurements were performed on a medium voltage XLPE cable at voltages from 8.5 to 65 kV (average field from 2.5 to 19 kV/mm). To assess the effect of mechanical strain on the conductivity of the insulation, the cable was wrapped around a tube with an outer diameter of 110 mm (max strain ...

Self-healing composites for high voltage electrical insulation

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258142

A self-healing electrical insulation material for high voltage apparatuses has yet not been developed. Such a material would have been very attractive for electrical components installed in conditions were service failures cause time consuming and very expensive replacements. This paper reports resu...

Degradation rates in high voltage subsea cables with polymeric water barrier designs

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258256

This paper presents results from numerical calculations of water ingress in a wet designed subsea XLPE cable equipped with a two-layered outer sheath, and results from water tree ageing at different relative humidity (RH) levels in an XLPE cable core. The results from the water tree ageing show that...

Non-Contact Surface Metrology of Degraded Conductor Screens in XLPE Cables

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1258147

Stress-induced electrochemical degradation (SIED) structures are likely initiated at the surface of the conductor screen of insulated XLPE cables with stranded aluminum conductors due to water ingress and corrosion. In time such structures initiate severe vented water treeing which significantly red...
