Available constructions

• 18 AWG 1 Pair Stranded (7 Strand) TFFN Twisted 600 Volt: Unshielded twisted pair for BAS control and signal runs where reliable performance and flexible routing are required. The twisted lay helps manage noise coupling in typical building environments and supports clean terminations in control panels and devices.
• 18 AWG 1 Triad Stranded (7 Strand) TFFN Twisted 600 Volt: Three-conductor twisted set for multichannel control, sensor loops, or I/O where a compact bundle simplifies pulls and panel organization. Stranded copper and TFFN construction balance durability with ease of installation.
• 18 AWG 1 Conductor Stranded (7 Strand) TFFN 600 Volt: Versatile single-conductor for point-to-point control wiring, jumpers, and device interconnects. Flexible stranding supports faster routing in tight spaces and clean terminations at field devices.

How this adds value to your next project

• Standardized BAS wiring across sites reduces installation time, simplifies commissioning, and streamlines maintenance.
• Twisted constructions for signal circuits and robust TFFN insulation help maintain performance across diverse mechanical rooms, risers, and plenum-adjacent pathways (per applicable codes and methods).
• SmartWire Glide lubrication and flexible stranding reduce effort during pulls, which can help lower labor costs and minimize jobsite slowdowns.
• Color options and the ability to request custom color/stripe combinations support faster identification and documentation across large facilities.

Whether you are standardizing a BAS specification, wiring a central plant, or scaling across multiple facilities, Windy City Wire provides a straightforward, field-proven SmartWire product set that keeps installations consistent and efficient.

Building Automation Triad Stranded Cables – Where They Fit and How They Deliver

Windy City Wire’s triad stranded low-voltage building cables are built for the day-to-day demands of commercial and industrial building automation. With a twisted, unshielded three‑conductor design and durable TFFN insulation rated to 600 volts, these cables support reliable control signaling and device power for a wide range of BAS applications. The triad format simplifies terminations and helps standardize wiring for 3‑wire devices across large facilities and multi‑building campuses.

Typical building systems and use cases

• HVAC control and instrumentation
  • 0–10 V analog control loops for VFD speed reference, damper/valve position, and economizer control
  • 3‑wire sensors and transmitters (e.g., pressure, humidity, IAQ) that require power, signal, and common
  • Actuator wiring where separate power, command, and feedback conductors simplify commissioning
  • Terminal unit controls for VAV boxes, fan coils, heat pumps, and unit heaters
• Lighting control
  • 0–10 V dimming control runs from controllers to fixtures or drivers
  • Power + signal + common for wall stations, daylight sensors, and occupancy sensors
  • Relay and contactor coil control wiring for panel-based lighting control
• Security and access control peripherals
  • Motion and REX devices needing power and a discrete signal return
  • Door position and auxiliary relays for status and interlocks
  • Low-voltage control ties between security panels and mechanical equipment
• Energy and building performance
  • Analog I/O to submeters, energy dashboards, and power monitoring relays
  • Control and feedback for demand-limiting strategies and peak-shaving sequences
  • Signal wiring for control valves on hydronic loops, heat recovery, and thermal storage
• Specialty controls and integration
  • Shading and daylighting control where a dedicated common improves performance
  • Equipment interlocks between BAS and life-safety/smoke control systems (when permitted by local code and project specifications)
  • Process and environmental control in labs, clean rooms, and manufacturing areas

Industries and facilities that benefit

• Commercial offices, mixed-use, and corporate campuses
• Healthcare, labs, and life sciences facilities
• Data centers and mission-critical environments
• Education (K‑12 and higher ed), municipal, and government
• Hospitality, retail, and entertainment venues
• Industrial plants, warehouses, and logistics hubs
• Multi-family residential and senior living communities

Why triad stranded for BAS?

• Three conductors where you need them: Ideal for 3‑wire sensors, 0–10 V control, and circuits that benefit from a dedicated common or feedback.
• Twisted construction for stable signaling: The triad twist helps maintain signal integrity and consistent readings over typical BAS run lengths.
• Stranded conductors for easy installs: Flexible, durable termination at controllers, actuators, and field devices—especially in tighter enclosures and raceways.
• TFFN, 600 V rated: Robust insulation and nylon jacketing support demanding commercial environments and a wide range of BAS control voltages.
• Unshielded efficiency: A cost-effective choice for most control spaces with moderate electrical noise; easier to strip, terminate, and route.
• Color identification options: Choose conductor sets such as Black/White/Red or Yellow/Blue/Orange to standardize field terminations and speed troubleshooting.

Application guidance

1. Match the circuit: Use the triad format for devices requiring power, signal, and common. Common examples include 0–10 V control, 3‑wire sensors, and relay/coil control with feedback.
2. Plan device counts and labeling: Map triad runs per controller I/O to streamline commissioning and future service.
3. Consider the environment: Unshielded triads work well in most mechanical and plenum-adjacent pathways with typical noise levels. Where high EMI is expected, review project specifications for shielding requirements.
4. Coordinate with the AHJ and spec: Always verify wiring methods, class of circuit, and routing with the project specification and local electrical code.

Who benefits on the project team

• Electrical contractors: Flexible pulls and straightforward terminations help maintain schedules and reduce rework.
• Systems integrators: Consistent color-coding simplifies I/O mapping, documentation, and diagnostics.
• Facility teams: Clear conductor identification and robust TFFN insulation support reliable, serviceable systems over the life of the building.

Common device connections supported by triad stranded cables

• 0–10 VDC control from BAS to VFDs, actuators, and dimming drivers
• 3‑wire transmitters and sensors (power, signal, common)
• Control relays, contactor coils, and status feedback
• Damper and valve actuators with separate position command and return
• Perimeter and interior environmental controls: temperature, humidity, CO2, pressure
