Topsolar cables, from Top Cable, become the best alternative when performing photovoltaic installations.

Connection of panels to the Low Voltage network in continuous current

The TOPSOLAR (PV) cable has been specifically designed to withstand the most demanding conditions between the panels and LV network in continuous current from a solar photovoltaic installation.

Its excellent proprieties make it the best cable for all LV installations:

• It has a useful life of 30 years at 90 ºC, being able to withstand up to 120°C continuously. Temperatures higher than 90 ºC are common in installations on rooftops. Normal cables with reticulated polyethylene or EPR insulation are designed for a maximum conductor temperature of 90 ºC and noticeably colder surroundings. It is demonstrated in tests that the TOPSOLAR (PV) cable shows high resistance to weather corrosion, abrasion, and chemical agents.

• Its allowable current is superior in identical sections to conventional cables. High-quality ethylene-propylene insulation of TOPSOLAR (PV) cables allows the conductor’s temperature to reach 120ºC, which implies important increases in allowable currents with regards to similar sections of conventional cables.

• It is halogen-free, fire-retardant and has reduced the emission of opaque fumes. It surpasses the tests for flame-retardants, fire-retardants, low emission of opaque fumes and low emission of toxic and corrosive gases, which on top of decreasing the collateral effects of fires on people, also protects the solar installations’ valuable electronic equipment due to its high fireproofing and the low corrosiveness of emitted gases.  

• It is fit for mobile services. The use of followers is frequent to get the most out of solar radiation. It should not be forgotten that in these cases the connection cables between mobile structures and the fixed parts are subject to movement, for which conventional cables are not suitable. The TOPSOLAR (PV) line demonstrates good mechanical properties even at low temperatures.

• It is more convenient to install due to its extraordinary flexibility and reduced diameter. casino . The cable is made of a flexible class 5 tin-plated copper conductor, high-quality insulation of ethylene propylene and an outer sheath of ethylene vinyl acetate (EVA). Its reduced outer diameter makes the cable more manageable and takes up less space in the wiring.

Cables for the Low Voltage network in alternate current

At the inverter’s output begins the LV network in alternate current, which ends in the connection point to the LV network or even the transformer, in the case of connecting to the MT network. In solar parks, this LV channelling in alternate current tends to be buried pipes. Moreover, in this type of application, the designers should evaluate the possible presence of rodents in any part of the installation. online casino . In this case the use of armoured cables should be considered, like those of the TOPSOLAR XZ1FA3Z-K type.

Cables for the Medium Voltage network

Top Cable offers two cable families:

• those insulated in reticulated polyethylene (XLPE)

• those insulated with ethylene propylene (HEPR)

Both in voltages up to 30 kV.

The X-VOLT range has its cold-shrinkable outer semiconductive layer, a quality highly valued by the installers, given that its easy removal is a critical factor when correctly preparing the cable tips for the making of joints and outlets, furthermore constituting a notable saving of time.
 
The X-VOLT RHZ1 cables, insulated in XLPE, are characterized by a good dielectric rigidity, low loss factor and high insulation resistance.

The X-VOLT HEPRZ1 cables, insulated with HEPR, can withstand temperatures of 105 ºC in continuous operation, demonstrating very good resistance to thermal aging and partial discharge.

In both cases, the cables can include elements sealed in the shield that impede longitudinal water propagation in case of breakdown of the sheath and/or elements for the longitudinal sealing of the conductor.

RWE Deutschland, Nexans and KIT launch "AmpaCity" project: the world’s longest superconductor system to replace inner-city high-voltage…

By admin, January 23, 2012 7:11 am

Monday, Jan 23, 2012

The “AmpaCity” project has been kicked off: The RWE Group and its partners are just about to replace a 1-kilometre-long high-voltage cable connecting two transformer stations in the Ruhr city of Essen with a state-of-the-art superconductor solution. This will mark the longest superconductor cable installation in the world. The three-phase, concentric 10 kV cable will be produced by Nexans and is designed for a transmission capacity of 40 megawatts. As part of this project, the Karlsruhe Institute of Technology will analyse suitable superconducting and insulating materials. multitenancy: This refers to the situation where a single instance of an appli- cation runs on an SaaS vendor’s servers, but serves multiple client organiza- tions (tenants), keeping all their hard drive recovery services separate.. This installation will also be the first to combine a superconducting cable with a resistive superconducting fault current limiter for overload protection. The limiter will be manufactured by Nexans unit specialized in superconductors, located in Huerth, Germany.

The project could herald a whole new dimension in the restructuring of inner-city networks. Following the successful completion of a two-year field test, it would be possible to install 10 kV superconducting links in large sections of the backbone of the Essen distribution network as part of efforts to release from high-voltage installations. In the medium term, this would lead to greater efficiency as well as lower operating and maintenance costs while simultaneously reducing land use. The dismantling of numerous 110/10 kV transformer stations would help to free up valuable space in inner-city areas. Thanks to the distinctive nature and ambitions of AmpaCity, the project is being supported by the energy research department of the Federal Ministry of Economics and Technology (BMWi). Research project total costs are approximately €13.5 million including government-funded €6 million.

Study highlights the economic efficiency of superconductors

The project was preceded by a detailed study in which a number of research institutes, under the leadership of the Karlsruhe Institute of Technology, worked alongside with the project partners Nexans and RWE to analyse the technical feasibility and economic efficiency of a superconductor solution at medium-voltage level. The study revealed that superconducting cables are the only reasonable alternative to high-voltage cables in city networks and that their use would mean that resource- and land-intensive transformer stations could be demolished. Although copper medium-voltage cables could also be used in inner-city areas to transmit high power, the cost efficiency of this solution would be cancelled out by the much higher ohmic loss. Furthermore, conventional medium-voltage cables for the Essen project are also out of question, as they require much more routing space: instead of a single 10 kV superconductor cable, five copper cables would need to be laid in parallel – often a largely impossible task given the limited space under the city streets.

Efficiency technology to soon compete with conventional solutions

State-of-the-art high-temperature superconductors (cooled with liquid nitrogen) such as those used in AmpaCity have been ready for deployment in energy-related applications for some years now, although they have yet to be used on a large scale. Thanks to improved production processes, superconducting wires are only now available in sufficient lengths and quantities. Superconductivity is an efficiency technology because it helps to protect material and energy resources. Experts anticipate that these innovative cables will soon be in a position to compete with copper solutions in energy-intensive applications. The BMWi understands superconducting equipment as an important component of future energy supply concepts.

Technical superiority of ice-cold conductors

The technical predominance of superconducting cables can be attributed to the material properties of the conductor. At temperatures of around -200°C, the material is transformed into an almost perfect electrical conductor being able to transport at least 100 times more electricity than copper. Despite the cooling jacket, the compact design of the superconductor means that it can transport five times the electricity as a similarly sized copper cable – and with much fewer electrical losses.

In order to reach its ideal conducting temperature, the concentric superconducting cable is cooled with liquid ni-trogen. Thus it can conduct high currents with minimal loss and smaller cross-sections than an adequate copper cable.
