High Voltage (HV) Cables and Extra High Voltage EHV) Cables up to 245 kV.
Established in 1966, Tratos has been involved in this emerging market segment, starting production of HV Cables up to 245 kV in 2009.
Tratos HV and EHV cables are distinguished by Tratos’ ongoing investment in the latest technology, materials and human resources needed to meet the highest safety and performance requirements demanded of HV and EHV cables installed in Electrical Transmission Systems around the world.
Tratos HV 76 kV to 132kV (145kV) and 38 kV to 66kV – (72.5 kV) cable is manufactured in accordance with IEC 60840, incorporating requirements from other relevant standards including IEC 60228; IEC 61443; IEC 60885; and HD632.
Constructed with triple-layer dry cure XLPE insulation the Tratos design controls the stress in the insulation reducing breakdown and leakage current in High Voltage (HV) cable systems. For installations where increased fire performance is required Tratos can supply cables with an LSZH outer sheath.
Applications include substations, power transmission and distribution for national power networks when the requirement is for underground not overhead cables, an increasing requirement to help protect areas of natural beauty or for localised biological and ecological reasons. 66 kV cables are now becoming more popular as subsea inter-array cables and connection to Windfarms and large Solar Farms. Designed to be maintenance-free, Tratos HV copper or aluminium conductor, triple extruded, dry-cured XLPE insulated cables offer exceptional long term reliability and performance. Tratos can also supply both wet and dry designs of MV and HV double wires armoured cables in weights of up to 85 tonnes for subsea applications.
Tratos work closely with manufacturers of High Voltage (HV) accessory manufacturers including HV joints, terminations and fixings.
