Nexans

Electrical Conductors

Madeco by Nexans continues to promote the development of renewable energies, by concluding a significant agreement with Sigdo Koppers Ingeniería y Construcción SA to provide cabling solutions to the Horizonte wind farm.

There will be 840 kilometres of electrical conductors, mainly aluminium medium voltage, which will be produced in collaboration with Nexans Indeco (Peru), one of the Nexans Group plants in the Andean region. Conductor design was optimized based on the requirements of the project, located in the municipality of Taltal, Antofagasta Region. The first deliveries are planned for May 2022.

Shearbolt Cable Lugs & Connectors

Jointing & Connecting MV Cables

Nexans manufacture an extensive range of slip-on, cold-shrinkable and heat-shrinkable cable terminations, joints and connectors for 11kV-33kV-66kV power systems – to complement and ensure their reliable performance a complete range of Cable Lugs & Connectors utilising shearbolt technology are available from Nexans.

The GPH range of electrical connectors from Nexans are compatible with their medium voltage ranges of joints (JTS) and terminations (MONO).

GPH medium voltage mechanical cable connectors and cable lugs provide excellent electrical contact and are suitable for aluminium and copper conductor ranges 1.5-1200sqmm up to 52kV (EN 60228 Classes 1 & 2).

M-Series mechanical connectors are assembled with multiple shear-off-head bolts and are therefore a reliable and economical way of connecting identical or different conductor cross-sections and conductor materials – they allow the safe connection of copper and aluminium conductors with cross-sections of #16 AWG up to 2,000 kcmil (up to 1200sqmm).

Nexans have launched a new mechanical power connector as part of their range of GPH cable connectors and cable lugs available for medium voltage cables. All connectors are available with either Allen shear bolts or outer hexagon shear bolts.

The new Nexans GPH mechanical connector M-Series is specified for connecting, jointing and branching large conductor cross-sections on medium voltage power cables up to 52kV.

Typical applications for the Nexans GPH Connector are connections of large scale wind farms and offshore wind farms to the MV power grid. The patented Nexans GPH shear-off head bolt clamps the conductor into the connector at the optimum contact force.

Connects, Joints & Terminates all Types of Copper & Aluminium Cables

Installation is simple and quick and the GPH mechanical connectors have been electrically tested according to IEC 61238-1-A.

As with all medium voltage cable lugs from Nexans GPH, the M-Series has been successfully tested according to IEC 61238-1, class A and ANSI 119.4

Nexans support international onshore and offshore renewable energy projects with an extensive range of 52kV medium voltage electrical distribution equipment including cable joints, terminations and Euromold screened separable connectors.

Nexans Successfully Achieves Electrical Type Test for 525kV DC GIS Cable Sealing End

Nexans 525 kV DC GIS Cable Sealing End

Nexans has achieved electrical Type Test of a 525kV DC Gas Insulated Switchgear (GIS) Sealing End according to CIGRE TB 496 with the cooperation of Siemens Energy

In the frame of the high voltage direct current (HVDC) market, the cables with an insulation composed of cross-linked polyethylene (XLPE) have emerged in the last ten years and allowed the deployment of innovative electrical grids in Europe and worldwide.

Nexans’ ecosystem encompasses best-in-class partners who share our values, working together to continually deepen our ability to stay a step ahead of what the market needs.

GIS type ends constitute an interesting component in the HVDC links due to the flexibility and compaction they allow in the connection of cables of different structures, especially in congested spaces such as an offshore platform. It is also suitable for use in back-to-back mode, thus constituting a mixed joint (e.g. between cables of different technologies).

• Nexans developed a dedicated GIS cable sealing end for a 525kV DC XLPE cable system. The studies on electrothermal aspects of the interface resulted in an optimized accessory design. The solution consists in a Nexans GIS termination plugged in a Siemens Energy DC GIS enclosure both compliant with IEC 62271-209 standards dimensions.
• The validation of the solution has been successfully completed through an electrical 525kV DC VSC Type Test according to CIGRE TB 496. The test was accomplished in Nexans Calais high voltage laboratory under the certification of an independent third-party. This technologic breakthrough allows Nexans to offer competitive products for the deployment of HVDC links with direct connection to DC GIS.

Nexans developed a dedicated GIS cable sealing end for a 525kV DC XLPE cable system.

At Nexans, we are leading the charge to the new world of electrification: safer, sustainable, renewable, decarbonized and accessible to everyone – connecting us all to new opportunities, technologies and behaviours that will build a better future.

Nexans Cable Leads Keep High Voltage Energy Transmission Flowing – 110kV, 132kV & 220kV

• uploaded by Chris Dodds | Thorne & Derrick Sales Marketing Manager

Nexans Cable Leads

High Voltage Energy Transmission Flowing – 110kV, 132kV & 220kV

The construction of new power plants and the growing demand for renewable energy sources has increased the need to expand and/or convert networks into transformer substations or onto overhead line towers.

Flexible high voltage cable leads are used by electrical utilities and contractors for emergency preparedness and use on substations and OHL (Overhead Lines). 

As a key player in the energy industry, Nexans is pleased to offer a safe and flexible component for such projects : pre-terminated temporary site cables.

Terminated Cable Leads

These high voltage cable leads are supplied pre-terminated and can be used to temporarily connect MV HV equipment in a high voltage network, e.g. as a bypass during construction or cable repair and servicing work, or during emergencies such as natural disasters or severe weather.

When faults occur in overhead or underground lines, temporary site cables make it possible to restore energy transmission rapidly. While modification work is underway in a transformer station, temporary connections can be rapidly installed between transformers and switchgear systems or overhead lines.

Temporary site cables are available from stock or can be manufactured to meet your specific requirements.

Flexible silicone rubber outdoor cable terminations facilitate use in any position and due to their low weight, the Nexans cable terminations can be operated without additional support.

Temporary leads have the same design as high voltage cables but with reduced insulation thickness, this facilitates a small bending radius making them easy to handle and install.

Nexans manufactures temporary cables in a variety of lengths across three voltage ranges: 110kV, 132kV and 220kV.

Pre-terminated temporary site cables

Pre-Installed Flexible Silicone Rubber Terminations for Simplified Installations 

Due to the conditions under which temporary site cables are installed, the cable accessories must be to easy to use and have a wide range of possible applications.

Nexans’ pre-installed flexible silicone rubber terminations facilitate use in any position.

Due to their low weight, the cable terminations can operate without any additional support structures. The monobloc design ensures the terminations are suitable for voltages from 72.5kV to 220kV offering maximum flexibility and operational reliability.

Advantages of Nexans Temporary Site Cables & Terminations 

• Optimized cable lead design for very small bending radii
• Reduced insulation thickness reduces weight and improve handling on site
• The Nexans pre-installed silicone rubber terminations are maintenance-free and routine tested for partial discharge up to a test voltage of 2.5 x U0. Following every use, a new partial discharge measurement can be performed on the cables in order to rule out possible damage.
• Single or 3-chamber drums make transportation and handling much easier
