Restraining EHV cables under fault conditions

摘要

The cable saddles (from Ellis Patents' Centaur range) were specified by Russian cable engineering and cable supply company, Systec LLC for use in the second phase development of the Zagorskaya Pumped Storage Plant, which is located in the administrative district's Sergiev Posad area. The plant uses two lakes at different altitudes to generate sufficient power to cope with Moscow's peak electricity demands, and when complete, will deliver 1,200MW of generated power and 1,320MW of consumable power. Centaur is a heavy-duty extruded aluminium saddle cleat that was designed and developed in-house by Ellis in response to a serious safety issue surrounding the restraint of high voltage and EHV cables up to 160mm in diameter.
