NSULATORS
 
Insulators are OHTL components installed between live conductors and earthed parts and 
subjected to mechanical and electrical stress. They are used to isolate the towers from the live 
wires that carry the electricity and are typically made of glass, ceramic or some form of 
composite materials. The insulators for the OHTL will be designed to ensure effectiveness during 
adverse climatic conditions during OHTL operation. 
All OHTL component will be designed and constructed to ensure safe operations in all climatic 
conditions that exists in the area where the OHTL will run through. 
2.3.2.2
Associated Facilities
Associated facilities are those which are not funded as part of the Project, but without which 
(or without their expansion) the Project would not be viable. 
As shown in the Grid Interconnection Option figure above, the National Grid of Uzbekistan 
(NEGU) will be responsible for the construction and operation of the OHTL associated facilities. 
The OHTLs under NEGU’s scope are defined below. 
Dzhankeldy 
– Sarymay
This will include a 500kV single circuit OHTL which will be approximately 120km. The expansion 
of the 500kV Sarymay sub-
station will also be under NEGU’s scope. 
 
According to the MOM “ Selection of Interconnection Option” held between MoE, 
NEGU, ACWA Power & Juru Energy, NEGU will follow official procedure with 
multilateral DFIs (i.e., EBRD) for securing funds and ensuring timely implementation 
of Sarymay 
– Dzhankeldy 500kV OHTL and Sarymay 500kV switchyard 
commissioning in line with planned Dzhankeldy WF Early Commercial Operation 
Date (ECOD). It is noted that NEGU stated that they have started discussions with 
EBRD on the financing of this alignment. 
LILO to Navoi 
– Murantau 
The LILO will be 500kV and will be u to 2X5km. This will connect to the: 
 
500kV single circuit 108km OHTL to Murantau 500kV sub-station. 
 
500kV single circuit 80km OHTL to Navoi 500kV TPP switchyard.

It is noted from the MoM that the facilities above are currently under construction.
Qurako’l 500kV sub-station 
 
This will include the expansion of the existing 
Qurako’l/Karakul
500kV bay. It is 
understood from ACWA Power that this will be under NEGU’s scope.
