電網結構-台電供電系統

Power Grid Structure - Taipower Power Supply System

  • Electricity generated by large-scale power plants within Taipower's supply system is first stepped up to Extra-high voltage levels of 345 kV via transformers, and then transmitted through highvoltage transmission lines.
  • Electricity is subsequently stepped down to 161 kV and 69 kV at Extra-high voltage substations and primary substations to supply large industrial and commercial users.
  • Through distribution substations, secondary substations, and distribution networks, voltage is further reduced to supply general consumers and residential users.

AI新革命來臨 黃仁勳點名台灘:能源是最大機會

Taiwan stands at the starting point of a new industrial revolution. Artificial intelligence will become ubiquitous across societies, enterprises, and individuals, significantly enhancing productivity and creating new applications. The so-called “AI factories” that support these applications require enormous amounts of energy.

UPS to PDU / Busway (External Rack Cabling): The UPS output routes to row-level PDUs, RPPs, or main busways, which then distribute power to each AI rack. This stage mainly uses 0.6/1kV flame-retardant power cables or prefabricated cable assemblies, engineered to support 3-phase 400V/480V and future 800V DC architectures.

Coolant Distribution Unit (CDU): The core equipment of data center liquid cooling systems, responsible for distributing coolant to server racks for high-efficiency cooling.

CDU Cabling & Piping: This primarily refers to the power cables and coolant lines connecting external sources to the CDU unit. Since the CDU is usually installed inside the rack, it simultaneously bridges both the "inside and outside" of the rack.

機櫃內用線高電流電子連接器用電鑰

Inside AI racks, power cables are the main solution for high-current electronic connectors, supporting high-power requirements like 400A to cope with intense server power consumption. These cables often feature high-temperature insulation to upgrade heat resistance and insulation performance during high-speed computing, replacing traditional PE materials. This design is applied in NVIDIA’s GB200 and GB300 NVL72 racks, where each cabinet utilizes around 10,000 lines.

With a 2000V voltage rating, these cables are used for external rack equipment connections. They feature solid or stranded copper conductors with rubber insulation and sheathing. Fully compliant with RoHS regulations, they offer superior insulation and flame retardancy, certified by the UL VW-1 vertical flame test.

AI CENTER建廠用線

img-26.jpeg

img-27.jpeg

10-33kV cables are widely used as primary transmission lines in AI data center medium-voltage grids, routing power from substations or microgrids to data halls or Pod modules. Featuring standard voltages of 11kV, 22kV, 25kV, or 33kV, these systems minimize distribution losses to fully support high-power density demands.
