Impact of Stress Cone & Joint Body Expansion Rate on Electric Field Stress

Layout of pre-moulded stress cones for elastomeric cable accessories is designed and optimized using computer calculations of electrical stress on the accessory. During installation, however, stress cones are expanded, thereby reducing thicknesses of the... Read More

The World’s Remarkable Transmission Structures

Over 20 years INMR has visited and reported on hundreds of transmission lines throughout the world – crossing deserts, rain forests, urban areas, towering mountains and other diverse landscapes. While the majority of these have involved fairly conventional... Read More

Toward More Aesthetic Power Lines

The issue of grid aesthetics is really a question of image. For example, the concept of ‘industrial soldiers marching across the landscape’ was used to support an entry in a 2008 competition for a new pylon to be used by Italian TSO Terna. This edited... Read More

Design Principles for External Insulation at Converter Stations up to 1100 kV

Design Principles for External Insulation at Converter Stations up to 1100 kV

External insulation is one of the critical design aspects for HVDC equipment at converter stations. This is especially the case for UHVDC systems. The basic design principal for such a system with energy transmission capability up to 10 GW is to achieve... Read More

Development & Implementation of 400 kV Eagle Transmission Tower

One of the consequences of the Danish Energy policy is that the transmission grid has to expand. Fluctuating wind generation places strong requirements on the grid because large amounts of energy have be transported from wind farms to demand centres in... Read More
