7 Presentation Skid substation introduction Challenges in substation load transfer Insufficient construction area - difficult to obtain or insufficient space for facilities, storage and operation. Potential safety risks - temporary loads on site are served by old equipment, which increases safety risks. Unacceptable long power-off time - complicated reconstruction methods increase power-off time. Difficult load transfer - the substation s existing old lines cannot take the load during reconstruction. Long construction duration - time needed for reconstruction is determined by the time needed for constructing the main building and assembly of equipment. TGOOD solution Thanks to TGOOD s rich R&D experience and the core technology used in skid mounted prefabricated substations, they can be used in widely different industry segments, worldwide, including mining, utility and infrastructure applications. The innovative design of the skid substation also means it can meet the required needs for load transfer. The skid mounted substation is designed to meet the needs of temporary power supply on construction sites, substation maintenance and substation load transfer. It is composed of a: HV/LV distribution equipment building Transformer module The main features of the skid substation are: Speed - fast movement, fast response, rapid deployment and fast energisation. Easy construction - the primary and secondary systems of the substation are integrated, the skid substation is manufactured, assembled and commissioned in the factory, on site construction is easy (no room, no walls, no cable trench, no complicated foundation). Compactness - highly integrated design, compact structure, able to meet ergonomic requirements. Optimized design - vibration reduction measures are taken into account for primary and secondary systems. Advanced technology - heat insulation, temperature and humidity control technology are applied to secure the stability of the operational environment inside the enclosure. Anti-corrosion - the best-in-class anti-corrosion technology is used to prevent the skid substation from rusting for 30 years. This enables the skid substation to be used in areas of high UV, high salt spray and other harsh environments. 5

12 Design and structure Components Circuit breakers with high performance of electromagnetic compatibility and anti-interference protection. Layout of skid substation 40.5kV and 12kV: the metal-enclosed switchgear is arranged in a single row and the maintenance corridor is set. 145kV: except for 40.5kV and 12kV substation, the additional HV HGIS is located on top of the 40.5kV/12kV building. Outdoor application The skid substation has a protection level of IP54. Easy construction - no house, wall, cable trench, foundation, or operator needed. Mobile application The pullable skid design is convenient for assembly, disassembly and transportation, helping meet mobile application needs. Sheet steel Insulation material Hot zinc spray Zinc coating Zinc painting Surface painting Anti-corrosion The enclosure and frame use a welded 4mm cold rolled steel plate construction with improved strength and tightness. The cabinet uses a double-layer structure to create a constant internal environment. An advanced anticorrosive process is used inside and outside the enclosure. Zinc plus protection and thermal sprayed zinc ensure that the enclosure is rust free for 30 years. The skid substation is well suited for use in dusty, contaminative and harsh environments. Enclosure design Impact resistance is provided by double layer metal sheeting. Use of fridge insulation technology provides heat conduction coefficient at 0.30W/m 2 C. The nonflammable foam fill provides heat insulation in summer and heat preservation in winter. Broken bridge heat insulation technology can ensure an ambient temperature of -40 C~+40 C (higher or lower temperature optional). Anti-vibration design Structural stress analysis and mechanical strength finite element analysis and verification are used for the reinforced frame design. The industrial rubber vibration isolation cushion and vibration isolation device ensure the connection strength of the switchgear and can limit low frequency vibrations. High-quality low-power, cold-rolled silicon steel sheets are used for the transformer strength to aid in anti-vibration. The entire core is compressed with uniform pressure when assembling to prevent the transformer core from loosening. The number of transformer substructure and structure restraint points has been increased. A dynamic isolation system is provided to improve the strength level of the fastener so that the transformer can be fixed on the vehicle platform safely and reliably. 10

13 Design and structure Auxiliary system (optional) Interlocking system Temperature control system Anti-condensation system Smoke alarm system Open door alarm system Lighting system Micro-positive pressure system Connection 40.5kV part uses overhead incoming line and outgoing cable. 12kV part uses incoming cable and outgoing cable. A dedicated cable cap protection is used for the incoming line, and a fullcopper explosion-proof outdoor cable connector is used for the outgoing line. The outgoing line is led out from the side of the cabinet without cable trenching, which is convenient when pulling the skid. Interlocking To prevent on-load closing, the disconnector cannot be opened or closed when the circuit breaker is closed. To prevent any incorrect opening or closing of the circuit breaker, it cannot be operated when the disconnector is closed. To prevent live earthing, the earthing switch cannot be operated when the circuit breaker or disconnector is closed. To prevent energizing when the earthing is connected, the circuit breaker or disconnector cannot be operated when the earthing is connected. To prevent unsafe access to a live bay, the lower door of the switchgear can only be opened when the earthing switch is closed. 11
