ELECTRICAL CHARACTERISTICS

Rated Voltage

600V

Conductor Conductivity

The aluminum conductor provides reliable electrical conductivity while reducing conductor weight compared with equivalent copper constructions.

Ampacity

Allowable ampacity depends on:

• Conductor size

• Ambient temperature

• Number of current-carrying conductors

• Installation method

• Raceway configuration

• Terminal temperature rating

• Applicable electrical code

Final allowable ampacity shall be determined according to the actual installation conditions.

THERMAL PERFORMANCE

The traditional TW designation is associated with a 60°C maximum conductor operating temperature. Where a higher temperature rating is required, THW, THHW, THW-2, THWN, or THWN-2 constructions may be more appropriate depending on the installation requirements.

MECHANICAL PERFORMANCE

AL TW is designed for fixed electrical installations and provides:

• Lightweight construction

• Good handling characteristics

• Suitable flexibility for applicable conduit installations

• Reliable insulation integrity

• Good resistance to normal installation handling

• Clear conductor identification

The cable should be protected against excessive pulling tension, crushing, sharp edges, and bending beyond the manufacturer's recommended limits.

INSTALLATION

AL TW may be installed in approved:

• Conduits

• Raceways

• Electrical panels

• Distribution equipment

• Other wiring systems recognized by applicable electrical codes

Installation should comply with the National Electrical Code (NEC) and applicable local regulations.

Aluminum conductors must be terminated using connectors, terminals, and lugs specifically approved for aluminum conductors.

Proper conductor preparation, connector compatibility, and specified tightening torque are important for long-term electrical reliability.

KEY FEATURES

• 600V rated

• 60°C wet and dry

• Electrical-grade aluminum conductor

• Thermoplastic TW insulation

• Lightweight compared with equivalent copper conductors

• Wide range of conductor sizes

• Suitable for general-purpose fixed wiring where permitted

• Available in multiple insulation colors

• Suitable for approved conduit and raceway systems

• Custom conductor configurations available

FAQ

What is AL TW?

AL TW is a 600V aluminum single-conductor building wire with thermoplastic insulation, designed for general-purpose electrical wiring where its construction and temperature rating are permitted.

What does TW mean?

TW identifies a traditional thermoplastic-insulated wire construction with a maximum conductor operating temperature of 60°C.

What is the voltage rating of AL TW?

The standard voltage rating is 600V.

Can AL TW be used in wet locations?

The TW designation historically includes wet-location capability, but its 60°C temperature rating and the specific product marking must be considered. The applicable code and certification should always be checked before installation.

What is the difference between AL TW and AL THW?

The main distinction is the temperature designation. Traditional TW is rated at 60°C, while THW is typically rated 75°C. THW is therefore generally preferred where higher continuous operating temperature capability is required.

What is the difference between AL TW and AL THWN?

Both are thermoplastic-insulated wire constructions, but THWN specifically identifies a wet-location construction and is typically rated 75°C wet/dry, while traditional TW is associated with a 60°C rating.

What is the difference between AL TW and AL THWN-2?

AL TW is traditionally rated 60°C, while AL THWN-2 is rated 90°C in wet and dry locations and provides substantially greater thermal capability.

Is aluminum suitable for feeder applications?

Aluminum conductors can be used in feeder and distribution systems when the conductor size, ampacity, termination equipment, and installation method comply with applicable electrical codes.

Can AL TW be installed in conduit?

Yes, where the specific TW construction is permitted by the applicable electrical code and product listing.

What sizes are available?

Typical conductor sizes can range from 14 AWG to 1000 kcmil, subject to the specific product construction and certification.

Can the insulation color be customized?

Yes. Standard and custom insulation colors can be supplied according to project requirements.

Is AL TW suitable for modern high-temperature applications?

TW is a relatively lower-temperature designation. Where the installation requires 75°C or 90°C operation, a suitable THW, THHW, THW-2, THWN, or THWN-2 construction should be selected according to the applicable code and product listing.
