Keywords:acceptance testing, cable, cable installation, cable selection. This attachment provides diagrams showing a high-level overview of the main transmission networks and interconnections for each region of the National Electricity Market (NEM) high-voltage transmission network. These diagrams approximate the AEMO Energy Management System (EMS) network model, but do. Construction of new 66KV S/Stns. Procurement of complete equipment for the 66KV S/Stns. Restoration of power supply in case of major transmission line failure due. 1. 1 This Code sets the minimum conditions that the Transmission Licensee must meet in carrying out its obligation to provide transmission services and to provide non-discriminatory access to the Transmission Licensee's transmission system. The Code also describes the rights and obligations of the. The design for all wood poles and Light Duty Steel Poles (LDSPs) construction is 115 kV with the following exceptions: In situations where the existing 60/70 kV transmission line has been reinsulated to 115 kV, note that if the existing substations are 60/70 kV (without a lightning arrester between. This Network Standard provides technical information in relation to Ausgrid's requirements for the design, construction and installation of underground sub-transmission lines and modifications to existing underground sub-transmission lines.
