Transition Joints Serve Growing Role

The population of installed paper-insulated cables at low and medium voltages is estimated to still represent over half of the underground networks in many countries. However, these days, virtually 100 percent of new cable installations are polymeric type.... Read More

Silicones & Cable Accessories

The recent INMR WORLD CONGRESS in Barcelona-Sitges offered a session dedicated to cable accessories. Expert presenters exchanged views about general technical trends in the industry but also about specific topics related to medium and high voltage cable... Read More

Dry Type Cable Terminations up to 170 kV

The traditional design of most outdoor cable terminations at the higher voltages has been based on a hollow core insulator made from either porcelain or a composite tube covered by silicone sheds. The insulators in both cases are equipped with a field control... Read More

New Joint Design Aims at Reducing Underground HV Cable Costs

Increasing power demand in urban areas combined with the goal of evergreater system reliability mean that many utilities will need to add new underground cable transmission. The challenge will be how to build such lines in the most cost-effective manner while... Read More

Design Innovations in MV Cable Joints

Recent years have seen different manufacturers introduce interesting design innovations when it comes to straight joints for medium voltage cables. In most cases, the principal advantage of these innovations – all more or less in a single joint – is... Read More

Silicone Elastomers for Cable Accessory Applications

The majority of power cables these days are extruded XLPE-insulated types. These cables consist of a conductor, an inner conductive layer, the main insulation layer, an outer conductive layer, an outer conductor and an outer insulation/jacket. At places where... Read More

Cable Accessories as Enablers for the Grid of the Future

Power grids and distribution networks currently face challenges such as increased urbanization and integration of renewable energy sources and related storage possibilities. These factors will lead to previously unconsidered energy flows as well as totally... Read More
