AT250MB Xflex Cable Boosts Industrial Power Reliability

Imagine your factory equipment suddenly shutting down due to cable failure, bringing production lines to a halt with losses mounting by the second. This nightmare scenario can be prevented by selecting the right cable. Today we examine a specialized solution for demanding applications—the AT250MB X-Flex high-flexibility power cable—and how it ensures stable power system operation.

The AT250MB X-Flex is a 250 MCM (kcmil) high-flexibility power cable. MCM (thousand circular mils) measures cross-sectional area, with 1 MCM equaling 0.0005067 mm². The 250 MCM specification indicates substantial current-carrying capacity suitable for high-power equipment. Its conductor comprises 2,527 finely stranded copper wires, providing exceptional flexibility for installation in confined spaces.

The "X-Flex" designation highlights the cable's core advantage—superior flexibility. Traditional power cables often prove rigid with large bend radii, complicating installation in complex industrial environments. The AT250MB X-Flex's multi-strand copper design enhances both flexibility and fatigue resistance, maintaining electrical integrity through repeated bending.

• Conductor: 250 MCM (2,527 x 30 strands) - Denotes current capacity and construction
• Insulation: 0.1 inch thickness - Ensures safety against short circuits
• Diameter: 0.835 inches - Facilitates proper space planning
• Voltage Rating: 600/1000V - Suitable for various power systems
• Temperature Rating: 105°C - Withstands high-temperature environments

The AT250MB X-Flex carries UL certification meeting standards UL 1284 (hook-up wire requirements), UL 1339 (high-temperature wire specifications), and UL 10269 (low-smoke zero-halogen standards). Additional certifications include:

• CSA and C-RU (Canadian Standards Association)
• NEC MTW & THW (U.S. National Electrical Code)
• NEMA WC51-1986(R1991) (Electrical Manufacturers Association)
• ASTM B-172 (Soft Copper Conductor Standard)
• CT and FT4 flame-test certifications

This cable serves diverse industrial applications including:

• Power supply equipment and transformers
• Control systems and switchgear
• Electronic circuits and instrumentation
• Battery/charger connections
• Motor leads and power distribution

The cable features:

• Abrasion-resistant construction
• Current ratings of 455A (free air) and 290A (conduit) at 30°C
• Flame-retardant PVC insulation
• Low-smoke, halogen-free materials where applicable

When specifying this cable, evaluate:

• Application requirements (flexibility needs, temperature exposure)
• Current demands with appropriate derating factors
• Relevant industry certifications
• Manufacturer reputation and quality standards

The AT250MB X-Flex cable combines flexibility, durability, and safety for reliable power transmission in industrial settings. Proper selection based on technical parameters and operating conditions helps prevent costly downtime while ensuring system reliability.
