Type CC Type CCT Covered Conductors (ASNZS 3675)

Application

Type CC and Type CCT Covered Conductors are overhead low-voltage cables manufactured in compliance with AS/NZS 3675, specifically developed for Australian and New Zealand distribution networks in bushfire-prone and high-risk environments.

These conductors consist of a hard-drawn aluminum or aluminum alloy conductor covered with dual-layer or triple-layer UV-resistant thermoplastic insulation.

• Type CC features a two-layer covering, offering basic insulation and resistance to accidental contact, trees, and environmental exposure.

• Type CCT includes a third carbon-blackened UV protection layer, enhancing durability in extreme solar radiation and long-term outdoor installations.
  
  

Both types maintain electrical continuity with ground, enabling effective system protection and fault detection—unlike fully insulated systems. They provide a safer alternative to bare conductors while preserving the simplicity of open-wire installation.

Type CC and CCT conductors are ideal for use in rural networks, agricultural areas, roadside lines, and regions requiring enhanced fire mitigation, especially under Australia’s bushfire compliance guidelines. They are compatible with standard pole hardware and deliver low maintenance, long service life, and improved public safety.
