Joints for HV Power Cables
The IXOSIL product range of cable terminations and joints for HV power cables includes slip-on joints for the entire spectrum of voltages from 72.5 kV to 550 kV – in each case with different shielding designs, with or without bonding or grounding cable.
The joints consist predominantly of pre-manufactured and routine tested silicone components, are water-resistant and optionally available with permanent metal, plastic or shrink-fit enclosures.
The well proven slip-on technology permits fast installation and the secure connection of cables with extruded insulation with copper or aluminium conductors. The electrical conductors are permanently connected using advanced SICON bolted connectors or conventional compression connector. Combinations of cables with different conductors and shielding systems are also possible.
IXOSIL Joints for Permanent Cable Connections
Voltage range from 72.5 to 550 kV
Simple slip-on technology, proven in many years of service

Due to the ever-changing data centre environment Roxtec seals were installed on several centres built for a multi-national technology company throughout the USA.
Roxtec seals would both protect their equipment and provide flexibility for continued growth. Site superintendents, project managers and installers of contractors Structure Tone, IES and Hunt Electric also consider Roxtec a best-fit solution for the industry. Jim Wagner, Senior Project Manager at Hunt Electric coments, “Roxtec is a great product, the best I have seen in the market based on flexibility.”
Roxtec Project facts
Project Description – Construction of data centre in multiple locations in the USA
Owner –Â Multinational technology company
Installations –Â Structure Tone, IES, and Hunt Electric
Applications –Â Walls, trenches and cable trays
Sealing Requirements – Fire-proof, watertight and air-tight
Future Capacity Included
The HVAC systems, power equipment and communications equipment must be updated continuously. Our openable and adaptable seals make it possible to leave room for future capacity. You can easily make changes and upgrades without cutting a new hole. This allows for a dustless re-entry into your contained sensitive environment. Roxtec offers a long-term partnership to protect your data centres and server halls against multiple risks such as fire, flooding and air leakage.
Unbeatable Sealing & Protection of Cables
Roxtec provided sealing solutions for both exterior and interior penetrations keeping water and fire from causing damage and downtime all while providing airtightness and increasing the efficiency of the data centre.
Contractor Approved
Roxtec seals are easy to install, adapt and reseal. Ross Catlett of IES states:
“It is significantly easier to install Roxtec than using solutions like foam and the bags that you have to pack and fill in.”
After participating in Roxtec’s training and becoming an approved installer he can now train new employees as they come onsite or continue on to future projects.
Why use Roxtec?
Watertight firestop
Air-flow management
Easy to use and install
Flexibility for changes
Built-in spare capacity
Dustless re-entry
Roxtec cable seals are used in cable vaults, duct banks, electrical substations, trenches and M&E building services protecting low, medium and high voltage power systems against numerous external risk factors:
Fire – A60, H120 Class bulkhead sealing for offshore classification against jet-fire or spray and prevention of suffocating smoke spread
Gas – ensure complete tightness against air and gas pressure or migration through cable ducts with DSEAR compliance
Water – prevent flood and water penetration into substations and buildings – avoid humidity and partial discharge conditions
Cables – withstand cable bending load in heavy power and high voltage cable seal applications
Pressure – protect against catastrophic sudden or constant pressure
Electrical – protect cables and electrical infrastructure against EMI, EMP and lightning strike effects
Particles – control levels of of dirt, dust, chemical and fumigants from entering buildings, cable ducts and substations
Blast – protect against vibration, shock-waves and the risk of explosion in industrial and hazardous area location

Virtual Conference
Subsea Power Transmission & Cabling 2021
With the growth of offshore power production and in order to meet net-zero, it is important to ensure high quality and reliable offshore grid infrastructure to integrate the growing offshore power production. Infrastructure development is also important to ensure the security of supply and to ensure cross-border energy trading. Talking about infrastructure development, new challenges in cable technology, design, installation and maintenance needs to be addressed as well.
Subsea Power Transmission & Cabling 2021 will bring together the most prominent European energy industry leaders in an exclusive closed-group and business-friendly environment for peer-to-peer networking to discuss challenges and opportunities of the strategic role of submarine power cable infrastructure, subsea power transmission and infrastructure development to support the expansion of offshore wind production and to secure the stability of power supply by sharing their business models and latest studies.
Bringing together decision-makers responsible for subsea power cables and offshore power transmission to discuss challenges and opportunities of the strategic role of submarine power cable infrastructure, subsea power transmission and infrastructure development.
