The Art of High Voltage Cabling
Yes, we can lay high voltage cable, above ground or below, through water and densely populated areas. We can splice, join and terminate. We can run system diagnostics, cable checks and bring in stock for installations. But that is just the beginning, at LORD we take our high voltage cables seriously.
We train with industry leaders in cables and accessories in order to remain at the cutting edge of cable technologies and rise to the challenge of every new project. We value visualizing, planning and finding the the right solution for every job. We are committed to environmental and personal safety every step of the way. This is the way of High Voltage Experts at LORD.
Cable Testing
Cable checks at the beginning and upon installation are followed up by maintenance testing. Maintenance testing is conducted during the operating life of a cable system. It is intended to detect deterioration of the system (in cable or accessories) so thatsuitable maintenance procedures can be planned. Don't trust your cable testing to just anybody, interpretation of cable testing results is the key to properly assess the characteristics of a cable!
Terminations
High Voltage cables terminations are varied and designd to reduce electrical stresses at the an end point. Outdoor terminations are highly reliable cable connection assemblies designed to connect extruded high voltage cables. They are used in the high voltage power grid for connecting overhead lines to equipment such as switchgear and transformers. The terminations can also be used to connect mobile energy solutions equipment. Indoor terminations for GIS equipment require expert handling to identify the unique configuration of each HV cable.
Splicing and Connecting
High Voltage Cables are required to be spliced in precise ways to insure the integrity of the cable. It takes experts to ensure the work does not become a future failure point in the electrical system. The High Voltage Experts team at LORD is familiar with the guidelines to handling a wide variety of HV cables including heat and cold shrink mechanisms, and the use of separable connectors.
Cable Servicing
The effective management of the existing networks requires different knowledge and experience,
as they are often of hybrid nature. At LORD we have are trained to provide a tailor-made service with the latest tools for real-time network diagnostics.
Ready When You Need Us
During an emergency, logistics and supply are key. We partner with high voltage cable, equipment and accessory providers so that when emergency strikes we can step into action ready to reconnect your grid.
News in High Voltage Cable Innovation
- The most recent technological innovation developed by Prysmian for HV outdoor terminations is a new type of filling medium that replaces the traditional silicon fluid. The new patented medium is a special environmentally friendly silicone-based compound that becomes partially “solid” - but still “flexible” - within a short time after the filling of the termination. The compound proves to be leak-proof, does not require maintenance nor fluid monitoring and remains sufficiently elastic to withstand even the highest difference in temperature, thus guaranteeing its full reliability.
Air Bags for cables - Prysmian now offers polymeric mechanical protection system for cables. The totally polymeric protection employed absorbs impacts and reduces the risk of permanent deformations and damage, thus protecting the sensitive underlying cable layers. These new cables with air bags offer savings to the total system cost, by allowing easier
handling and longer delivery lengths, with a subsequent reduced need for cable joints.
