250 MCM 7 Stranded Bare Copper Conductor Soft Drawn Wire

Other Names For 250-7 stranded bare copper conductors:

250-7 stranded bare copper wire, 250-7 stranded bare electrical wire, 250-7 bare copper ground wire, 250-7 raw copper wire, 250-7 bare earth wire, 250-7 hard-drawn copper wire, 250-7 medium-hard copper wire, 250-7 soft annealed copper wire

About 250-7 Stranded Bare Copper Wire:

Stranded Bare Copper Wire (class A) is an electrical wire suitable for overhead transmission and distribution. Flexible stranded copper wire (classes B and C) is designed for uninsulated hook up, jumpers, and grounds in electrical construction. The wire is uncoated and unalloyed, which lets the customers enjoy the pure benefits of a copper conductor. Bare conductors of this electrical wire exhibit superior conductivity compared to insulated versions.

250-7 Stranded Bare Copper Wire Applications:

250-7 Stranded bare copper wire is used for heavy-duty applications, including:

• Industrial Grounding
• Substations for connecting transformers, circuit breakers, etc.
• Overhead Transmission
• Power Distribution
• Bus Bars and Panel Boards
• Large Machinery
• HVAC Systems
• Mining Applications

250-7 Stranded Bare Copper Wire Construction:

Conductor:

Stranded Bare Copper Wire has a stranded copper conductor per ASTM B-1, B-2 and B-8. The conductor is available in hard, medium-hard, and soft-drawn combination unilay temper. Some of the advantages of copper in cables include conductivity, tensile strength, and the properties of the tensile expansion.

APPLICATIONS:

Solid and stranded (classes AA and A) bare copper are suitable for overhead transmission and distribution applications.
Stranded conductor of greater flexibility (classes B and C) are suitable for uninsulated hook up, jumpers, and grounds in
electrical construction. Soft Drawn copper is unilay construction.

SPECIFICATIONS:

• B-1 Hard-Drawn Copper Wire.
• B-2 Medium-Hard Copper Wire.
• B-3 Soft or Annealed Copper Wire.
• B-8 Concentric-Lay-Stranded Hard, Medium-Hard or Soft Copper Conductor.
• B-33 Tinned Conductors
• B-787 19 Wire Combination Unilay-Stranded Soft copper wire.

CONSTRUCTION:

Bare copper, solid or stranded. Available in tempers hard, medium-hard, or soft. Stranded conductors are concentrically
stranded in hard and medium-hard tempers and are Combination Unilay stranded in the soft-drawn temper.
