AL XHH

Aluminum XHH 600V Building Wire

PRODUCT DESCRIPTION

AL XHH is a 600V aluminum single-conductor building wire designed for power distribution, feeder, branch circuit, industrial, commercial, and utility electrical applications.

The cable features an electrical-grade aluminum conductor insulated with cross-linked polyethylene (XLPE) thermoset insulation. XHH construction provides excellent thermal stability and reliable electrical insulation for demanding fixed-wiring applications.

With a typical maximum conductor operating temperature of 90°C in dry locations, AL XHH provides higher thermal performance than traditional 60°C TW constructions and is suitable for installations where thermoset insulation is preferred or required.

The lightweight aluminum conductor provides an economical alternative to copper for properly designed and code-compliant electrical systems.

ELECTRICAL CHARACTERISTICS

Rated Voltage

600V

Conductor Conductivity

The aluminum conductor provides reliable electrical conductivity with substantially lower density than copper, allowing reduced conductor weight in appropriately designed systems.

Ampacity

Allowable ampacity depends on:

• Conductor size

• Ambient temperature

• Number of current-carrying conductors

• Installation method

• Raceway or cable tray configuration

• Terminal temperature rating

• Applicable NEC requirements

The final allowable ampacity shall be determined according to the actual installation conditions and applicable electrical codes.

THERMAL PERFORMANCE

The XHH insulation system provides a 90°C maximum conductor operating temperature in dry locations.

Where wet-location installation is required, an appropriate wet-rated construction such as XHHW-2 should be selected when permitted by the applicable product listing and electrical code.

MECHANICAL PERFORMANCE

AL XHH is designed for fixed electrical installations and provides:

• Good mechanical stability

• Low conductor weight

• Reliable insulation integrity

• Good resistance to normal installation handling

• Suitable flexibility for conduit installation

• Stable performance under normal operating conditions

• Clear conductor identification

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

INSTALLATION

AL XHH may be installed in approved:

• Conduits

• Raceways

• Electrical panels

• Switchboards

• Distribution equipment

• Cable trays where permitted

• 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.

FAQ

What is AL XHH?

AL XHH is a 600V aluminum single-conductor building wire using XLPE thermoset insulation and designed for 90°C operation in dry locations.

What does XHH mean?

XHH identifies a thermoset-insulated wire construction generally using cross-linked polyethylene insulation with a 90°C dry-location temperature rating.

What is the voltage rating of AL XHH?

The standard voltage rating is 600V.

What type of insulation does AL XHH use?

AL XHH uses cross-linked polyethylene (XLPE) thermoset insulation.

Can AL XHH be used in wet locations?

Standard XHH is generally associated with dry-location use. If wet-location capability is required, an appropriate construction such as XHHW-2 should be selected when its product listing and applicable code permit the intended installation.

What is the difference between AL XHH and AL XHHW-2?

AL XHH is typically rated 90°C dry, while AL XHHW-2 is designed for 90°C wet and dry locations.

What is the difference between AL XHH and AL THHN?

Both may provide a 90°C dry temperature rating, but they use different insulation systems and designations. XHH uses XLPE thermoset insulation, while THHN uses a thermoplastic insulation system with a nylon jacket.

Is aluminum suitable for feeder applications?

Yes. Aluminum conductors are widely used in feeder and power distribution applications when properly sized and terminated using equipment approved for aluminum conductors.
