A wireline tensioner includes at least one sheave, a first accumulator unit, a second accumulator unit, a hydraulic distribution system, and a hydraulic cylinder unit which is operatively connected to the at least one sheave, to the first accumulator unit and to the second accumulator unit via the hydraulic distribution system. The first accumulator unit receives hydraulic fluid from the hydraulic distribution system at a first hydraulic pressure. The second accumulator unit receives the hydraulic fluid from the hydraulic distribution system at a second hydraulic pressure. The first hydraulic pressure is lower than the second hydraulic pressure.
