Product Information

Specification

250 MCM XHHW Aluminum Cable 600V

Allowable Ampacity for 250 MCM XHHW Aluminum Cable 600V at 75°C: 205 Amps

Allowable Ampacity for 250 MCM XHHW Aluminum Cable 600V at 90°C: 230 Amps

Applications:

These electrical wires, also known as XHHW-2 cables, are primarily used for power distribution, in both wet and dry places, with ambient temperatures not exceeding 90°C. Voltage rating for this electrical wire, XHHW-2 cable, is 600V. 

Due to high 250 mcm aluminum wire ampacity, here are the applications:

• Service entrance
• Feeder circuits
• Industrial equipment
• Conduit systems
• Busbars and power distribution
• Renewable energy installations
• Backup generators

Also Known As:

250 mcm aluminum wire, 250 kcmil aluminum wire, 250 xhhw cable, 250 hxxw cable, 250 rw90 cable, 250 rw90 wire, 250 type se cable style u type xhhw, 250 xhhw, 250 southwire xhhw, 250 xhhw insulation, 250 aluminum wire, xhhw aluminum wire, 250 mcm aluminum

Standards:

• XHHW-2 meet or exceed the following standards: 
• UL standard 44 
• Requirements of the National Electrical Code 
• ASTM standards B 800, B 801 
• Federal Specification J–C-30B 
• Sunlight resistant

Construction

Conductors:

XHHW-2 conductor is a soft drawn bare 8000 series aluminum, with Class B stranding per ASTM. Stranded conductors reduce power loss and are also easier to use in applications where flexibility is vital. 

Insulation:

XHHW-2 has abrasion, heat, and moisture resistant cross-linked polyethylene insulation. Cross linking a polyethylene helps to achieve an excellent strength that makes the material suitable for covering this cable used in harsh conditions like direct burial installation.
