Type AC(BX) Steel Armored Cable | Galvanized Steel Interlocked Armor | 600V THHN Conductors

Building Wires Industrial Cables UL Certified14
Description

Product Overview

Type AC(BX) Steel Armored Cable is a versatile, durable electrical cable designed for safe and reliable power distribution in commercial, industrial, and multi-residential applications. Featuring interlocked galvanized steel armor and copper conductors with THHN insulation, this cable combines mechanical protection, corrosion resistance, and high-temperature performance. Compliant with UL 4, UL 83, and NEC standards, it is ideal for exposed or concealed installations in dry environments.

Key Features

  • Interlocked Galvanized Steel Armor: Provides superior mechanical protection against physical damage and corrosion.

  • Copper Conductors: Solid or stranded THHN-insulated conductors rated for 90°C in dry locations.

  • Integrated Grounding System: Includes a 16 AWG aluminum bonding wire and a copper grounding conductor for NEC compliance.

  • Fire & Moisture Resistance: Flame-retardant THHN insulation paired with moisture-resistant paper wrap for enhanced safety.

  • Flexible Installation: Suitable for cable trays, raised floors, plaster embedding, and environmental air-handling spaces (NEC 300.22(C)).

Technical Specifications

  • Standards Compliance: UL 4 (Armored Cable), UL 83 (Thermoplastic Insulated Wires), NEC.

  • Conductor Sizes: Available in standard AWG sizes (customizable upon request).

  • Flame Performance: Flame-retardant insulation meets NEC requirements for vertical flame tests.

  • Environmental Suitability: Dry locations only. Not rated for direct burial or wet environments.

Applications

Type AC(BX) Cable is engineered for:

  • Power Distribution: Branch circuits, feeders, and service entrances in commercial/industrial buildings.

  • Lighting & Control Systems: Exposed or concealed wiring in plenums, walls, and ceilings.

  • IT Infrastructure: Under raised floors for data centers (NEC 645.5(D)).

  • Air-Handling Spaces: Approved for environmental air ducts (NEC 300.22(C)).

  • Cable Trays & Raceways: Compatible with standard raceway systems.

Installation Guidelines

  • Bending Radius: Minimum 5x cable diameter to prevent armor damage.

  • Securing: Use NEC-approved clamps or straps at intervals ≤ 4.5 ft.

  • Grounding: Armor must be bonded via the integral aluminum wire and copper ground.

  • Prohibited Uses: Avoid direct burial, wet locations, or corrosive environments.

Why Choose Type AC(BX) Cable?

  • Durability: Galvanized steel armor resists impact and environmental wear.

  • Safety: Dual grounding system ensures compliance with NEC fault-current requirements.

  • Versatility: Suitable for both power and low-voltage signal circuits.

  • Cost-Effective: Combines armor and grounding in a single assembly, reducing labor costs.
