A metal sheathed cable includes an optical unit and a control unit helically twisted together, a grounding wire unit distributed in the gaps between the optical unit and the control unit to form an inner layer cable core, a filler watertightly filled into gaps among the optical unit, the control unit and the grounding wire unit, and a taped covering arranged outside the inner layer cable core; a power unit and a filling core helically twisted around the inner layer cable core, the grounding wire unit distributed in the gap between the power unit and the filling core, the filler watertightly filled into gaps among the power unit, the grounding wire unit and the filling core, and the taped covering arranged outside the outer layer cable core; an inner protective layer wrapped outside the outer layer core, and a sheathing layer twisted outside the inner protective layer.

Metal sheathed cable designed on the basis of torque balance and design method thereof

A tripolar VSC-HVDC system and method include a rectifier and an inverter formed by a three-phase six-bridge arms modular multilevel converter (MMC) respectively, and two converter valves are arranged on the DC side of the rectifier and inverter respectively. The midpoint of upper and lower converter valves of the rectifier and inverter are connected with a poleDC line by a smoothing reactor. Triggering of the upper and lower converter valves is controlled to change the DC voltage polarity of the poleperiodically, and tripolar DC transmission is realized by modulating current orders of the three poles.
