June 2011 Versailles Congress Centre - Jicable'11 - 8th International Conference on Power Insulated Cables



Four high-level tutorials will be given by professors during the Sunday afternoon of June 20th, 2011 for a limited number of people:

Registration to these tutorials may be made by use of the registration form attached or through internet.

T1: Towards an underground distribution network

By Alain DOULET, Former Technical Manager, ERDF

Environmental constraints, local pressures on techniques for building distribution networks are becoming commonplace. This can lead to the replacement of overhead techniques by underground techniques for the creation of new networks but it can also include transforming existing overhead lines into underground networks.

These guidelines may concern urban, suburban, but also rural networks. Yet, an underground network should not be considered as an overhead network buried underground. The choice of an underground network structure largely impacts the whole traditional business chain of the Distributor: network design, engineering, operations, maintenance. Beyond that, important aspects are affected by such an option: regulatory matters, for workers security, stakeholders and for the public, competencies. Approach to the issue of quality - the number and duration of predictable and unpredictable cuts - is strongly impacted. Finally, it is necessary to establish an economic balance upstream of any decision in order to identify the resources needed for the deployment of such a choice.

The tutorial will aim to give an overview of all these questions essentially as a tool to help in the decision making process for technicians to build such approaches to change, then to describe some efficient solutions as a starter for a possible discussion.

T2: Accessories for high voltage extruded cables

By Henk GEENE, Prysmian Cables and Systems B.V.

Since the introduction of HV extruded cable systems more than 30 years ago, significant improvements have been made in the design of its accessories.

Nowadays, the market has almost completely moved towards the use of pre-molded (factory made and tested) accessories. Although with these accessories the reliability of extruded cable systems has significantly improved, there are still important aspects that need to be taken into account during its design and installation. The Tutorial will focus on these accessory related aspects and will include the results of recent work performed by CIGRE.

Topics to be discussed:

T3: Electrical modelling of underground links


The tutorial involves 4 parts:

T4: Service experience of high voltage under-ground and submarine power cables

By Robert ROSEVEAR, Southampton Dielectric Consultant Ltd

In recent years, significant quantities of land and submarine cables and accessories have been installed and the associated technology and laying techniques have matured and evolved. With the increasing demands on electrical power transmission and distribution systems, significant quantities of cable are currently being installed.

In 2008, CIGRE WG B1.10 completed a survey to collect and analyse data relating to the installed quantities of underground and submarine cable systems rated at 60 kV and above together with the service experience and the performance of existing underground and submarine cable systems. The CIGRE Technical Brochure TB 379 summarizing the findings was published in April 2009. The tutorial is based on this work. A 5 year period ending december 2005 has been considered for land cables compared to a 15 year period ending similarly for submarine cables.The previous statistics published some twenty years ago have therefore been updated and some emerging trends identified.
