Midal Cables ACCC® (Aluminum Conductor Composite Core)
/
ACCC® (Aluminum Conductor Composite Core) cable is an advanced overhead power line conductor that offers enhanced efficiency, capacity, and reliability for electrical transmission. It replaces traditional Aluminum Conductor Steel Reinforced (ACSR) cables and other high-capacity conductor systems.
Structure of ACCC® Cable:
Composite Core: The heart of an ACCC® cable is a composite core made from carbon and glass fibre. This core is designed to be lightweight yet extremely strong and durable.
Aluminum Strands: Concentric layers of aluminum strands surround the composite core. These strands conduct electricity. The aluminum used is typically high-purity and annealed for better conductivity.
Key Characteristics:
High Efficiency: Using a composite core reduces the overall weight of the conductor, allowing for more aluminum in the same diameter or profile. This increases the current-carrying capacity without a corresponding increase in weight or sag.
Reduced Sag: The lighter composite core allows for less sag than traditional steel-core conductors. This can be crucial for maintaining safe clearances above ground, especially over long spans.
Lower Line Losses: ACCC® cables exhibit lower electrical resistance than traditional conductors, which results in lower energy losses. This is especially important for long-distance transmission lines.
Improved Thermal Performance: The composite core has significantly better thermal properties than steel, enabling the cable to operate at higher temperatures without degradation.
Enhanced Durability: The carbon and glass fibre core does not corrode or fatigue as metal cores might under cyclic loads, providing a longer service life under dynamic environmental conditions.
Applications:
Upgrading Existing Lines: ACCC® cables, thanks to their lightweight and high-capacity nature, are often used to upgrade existing power lines without the need to replace or strengthen existing towers.
Long-distance Transmission: Suitable for long-distance transmission lines where reduced line losses and high capacity are critical.
High-load Networks: These are ideal for networks that experience high peak loads, such as those in densely populated urban areas or industrial sectors.
Advantages Over Traditional Conductors:
Increased Capacity: ACCC® cables can carry about twice the current of equivalent ACSR cables.
Energy Efficiency: Reduces line losses by 25% to 40%, which can result in significant energy savings and reduced greenhouse gas emissions over the installation's lifespan.
Infrastructure Savings: Using existing structures without significant modifications can lead to considerable cost savings in upgrades and new installations.
ACCC® cables are part of a new generation of conductors designed to meet the growing demands for efficiency and capacity in the power transmission industry. This makes them a preferred choice for modernizing the grid and enhancing renewable energy integration.
