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)

Why Choose AA-8000 Aluminum Alloy Over Copper?



Feature AA-8000 Aluminum Alloy Copper
Weight ~50% lighter Heavier
Cost ~40-50% lower Higher
Creep resistance Excellent (AA-8000 specific) Excellent
Termination compatibility Requires AA-8000 rated lugs Standard lugs work
Corrosion resistance Good Very good
Conductivity (% IACS) ~61% 100%
Flexibility Good (compact stranding) Very good

AA-8000 aluminum alloy is specifically designed for electrical applications and, when properly terminated with compatible connectors, performs reliably equivalent to copper.

Standards Compliance



Standard Description
ASTM B800 Standard specification for AA-8000 aluminum alloy wire
ASTM B801 Standard specification for AA-8000 aluminum alloy conductors
UL 83 Thermoplastic-insulated wires and cables
UL 44 Thermoset-insulated wires and cables (XLPE)
CSA C22.2 No. 38 Aluminum alloy wire and cable (Canadian standard)

Comparison with Standard Aluminum (1350) Conductor



Feature AA-8000 Alloy 1350 EC Aluminum
Creep resistance Excellent (special alloy) Poor (prone to loosening)
Termination reliability High (with proper lugs) Low (requires retorquing)
Flexibility Good (compact stranding) Poor
Conductivity ~61% IACS ~61% IACS
Code compliance Required for most modern applications Not recommended for terminations

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.
