AN ALTERNATIVE METHOD OF INCREASING THE TRANSMISSION PERFORMANCE OF A CONVENTIONAL 110 kV CABLE LINE
(Journal of Energy Technology, 2019-11)The purpose of this paper is to show that a significant increase in the ampacity of a 110 kV underground cable line is achievable, if a hydronic asphalt pavement system is applied along the entire line, and if the cable ... -
Controlling the thermal environment of underground cable lines using the pavement surface radiation properties
(IET Generation, Transmission & Distribution, 2018-05-03)The main purpose of this study is to show how the emissivity and absorptivity of a pavement surface aboveunderground cables affect their ampacity. The use of cool pavements whose surfaces absorb less heat ... -
The effect of aging of surface non-metallic coatings on the ampacity of medium voltage rectangular bus bars
(The 7th Virtual International Conference on Science, Technology and Management in Energy (eNergetics 2021), 2021-12)There are two major types of non-metallic coatings for bus bars: oil-and epoxy-based coatings. The oil-based coatings have a limited lifespan of a few years, while the epoxy-based ones have a lifespan of over ten years. ... -
The effect of solar radiation on the ampacity of an underground cable with XLPE insulation
(The 4th Virtual International Conference on Science, Technology and Management in Energy (eNergetics 2018), 2018-10)The main purpose of this paper is to quantify the thermal effect of solar radiation on the ampacity of a low voltage underground cable with cross-linked polyethylene (XLPE) insulation. The quantification was performed for ... -
Eliminating the effect of hot spots on underground power cables using cool pavements
(Electrical Engineering, 2019-10-24)It is well known that hot spots limit the ampacities of underground power cables. There are many commonly applied methods to control the thermal environment in hot spots of underground power cables. However, applications ... -
INCREASING THE AMPACITY OF UNDERGROUND POWER CABLES BY AN APPLICATION OF PHOTOVOLTAIC PAVEMENTS
(2018-10)This article shows that a significant increase in the ampacity of an underground cable line can be achieved, if a photovoltaic pavement in combination with a ventilation channel is applied along the entire length of the ... -
Increasing the ampacity of underground power cables by an application of photovoltaic pavements," The 6th International Conference on Renewable Electrical Power Sources
(The 6th International Conference on Renewable Electrical Power Sources "6th ICREPS", 2018-10)This article shows that a significant increase in the ampacity of an underground cable line can be achieved, if a photovoltaic pavement in combination with a ventilation channel is applied along the entire length of the ... -
Modelling the thermal effect of solar radiation on the ampacity of a low voltage underground cable
(International Journal of Thermal Sciences, 2018-08)Compared with other underground cables, low voltage cables are most intensely heated by the sun due to the low laying depth. Accordingly, the main purpose of this paper is to show how the heat of solar radiation affects ... -
A review on new methods for increasing the ampacity of underground power cables: Cool and photovoltaic pavements
(The 6th International Conference on Renewable Electrical Power Sources (6th ICREPS), Belgrade, Serbia, 2018-10)The introduction of cool and photovoltaic pavements in underground power cable engineering can contribute to reducing global warming and our dependency on fossil fuels. In this case, a cool or photovoltaic pavement would ...
