ZMN Substation & its Interconnecting Underground Cables ESIA - Final. 4. • Connections with the 220 kV existing underground cables (networks):. The power system network consist of some element and these element consumer, so we make step down from 220/169 kv then from 169/133 kv then from. the project consists of a high‐voltage 220 kV transmission line for a length of 69 km within the Sudanese territory and 100 kilometers within the Egyptian 18‏/02‏/2019 — The article presents simulation results performed for a complex intersection, while 25 or 2 х 25 kV TN is crossed by a three-circuit 110-220 kV interconnection transmission line to compensate the receiving end open circuit voltage to the specified level (220 KV) at Gadaref Substation. The line resistance and inductance are. 0.0195 0 and 0.63 mH per Km. the voltage at the receiving end is required to be kept constant at 10 KV. Determine: (vs). 3-2 Power-Voltage (PV) Characteristic for Radial Line. 16. 3-3 System Studied Description. 18. 3-4 Arranging of 220kV Transmission Line. The aim of this research is to improve the voltage profile of Atbara –Port Sudan 220kv transmission line. This line has witnessed considerable voltage drops بواسطة AH M El-Sayed · 2009 — double line of circuits with a length of 150 km. The original voltage and current for this transmission line are 220 kV and 200 A,kV,750kV,420kV,220kVand110kV).Electricityisusuallytransmittedoverlongdistancesthrough overheadpowertransmissionlines.
