TTU Cable 600V – AL(AA-8000)/XLPE/PVC – Aluminum Alloy Power Cable for Underground Industrial Applications

Product Overview

The TTU Cable 600V – AL(AA-8000)/XLPE/PVC is a specialized transformer tap unit (TTU) cable designed for secondary distribution networks, transformer connections, and service entrance applications. Rated at 600V, this cable features AA-8000 series aluminum alloy conductor, XLPE insulation, and a PVC outer sheath.

AA-8000 aluminum alloy provides excellent creep resistance, flexibility, and corrosion resistance – making it a reliable and cost-effective alternative to copper for low voltage distribution. The XLPE insulation offers high thermal rating (90°C) and superior dielectric strength, while the PVC sheath provides durability and moisture protection.

Voltage rating: 600V
Conductor material: AA-8000 series aluminum alloy (compact stranded)
Insulation: XLPE (Cross-linked Polyethylene)
Sheath: PVC (Polyvinyl Chloride)
Standards: ASTM B800, ASTM B801, UL 83, UL 44 (optional)

Frequently Asked Questions (FAQ)

Q: What does TTU cable stand for?
A: TTU stands for Transformer Tap Unit. These cables are specifically designed to connect pad-mounted transformers to secondary distribution networks at 600V.

Q: Why use AA-8000 aluminum alloy instead of standard aluminum?
A: AA-8000 series aluminum alloy is specifically formulated to address the creep and termination issues of standard EC aluminum (1350). It offers excellent creep resistance, making terminations more reliable and maintenance-free.

Q: Can I terminate AA-8000 cable with standard copper lugs?
A: No. AA-8000 aluminum alloy requires connectors specifically rated for aluminum (typically tin-plated or bi-metallic lugs) to prevent galvanic corrosion and ensure proper contact pressure.

Q: Is this cable suitable for direct burial?
A: Yes, the PVC outer sheath provides good moisture resistance. For direct burial applications, we recommend confirming that the specific PVC compound is rated for underground use.

Q: What is the temperature rating of the XLPE insulation?
A: The XLPE insulation is rated for 90°C continuous operation, 130°C emergency overload, and 250°C short circuit conditions.

Q: Do you provide free samples?
A: Yes, we provide free samples of the TTU cable. The customer is only responsible for the shipping cost.

Q: What is the minimum order quantity (MOQ)?
A: MOQ depends on the conductor size.
