Building Wire Cable THW 250 MCM Copper Conductor 37 Strands 600V

Building wire cable THW 250 MCM (Thousand Circular Mils) with a copper conductor composed of 37 strands, rated for 600V, is designed for high-current, heavy-duty electrical applications. The 250 MCM size provides a high ampacity suitable for main feeders, industrial equipment, and large electrical loads. The conductor's 37-strand construction enhances flexibility, making installation easier in complex or confined spaces compared to solid conductors. The THW insulation offers excellent heat and moisture resistance, ensuring durability in both indoor and outdoor environments.

Cable THW 250 Application

The copper conductors type THW are used for power and lighting circuits in industrial, commercial and residential facilities where it is required of more security, just as it is specified in the National Electrical Code. This type of conductor can be used in dry and wet places; its maximum temperature of operation is of 75 ºC and its voltage of service for all the applications it is 600 V.

Cable THW 250 Standards

• ASTM B-3: Copper Annealed or Soft Wires.
• ASTM B-8: Copper Stranded Conductors in Concentric Layers, Hard, Semi-hard or Soft.
• UL - 83: Wires and Cables Insulated with Thermoplastic Material.
• NEMA WC-5: Wires and Cables Insulated with Thermoplastic Material (ICEA S-61-402) for Transmission and Distribution of Electric Power

CONSTRUCTION :

Cable THW 250 Construction

•Single conductor copper insulated with polyvinylchloride (PVC), solid or stranded, tinned or bare soft annealed copper per ASTM B-3, B-8, B-33, and complying with the physical and electrical requirements of UL standards 83 and 1851.
• Identified by surface marking indicate manufacturers identification, conductor size, voltage rating, and UL Type TW and THW designations.
