This 12 AWG, 7-conductor shielded VNTC (Vinyl Nylon Tray Cable) is a dual-rated Type TC-ER industrial cable, designed for multi-circuit control applications requiring robust protection against electromagnetic interference (EMI). The TC-ER (Exposed Run) rating provides superior installation flexibility, allowing the cable to transition from a tray to equipment without the need for conduit.

Key Features of 12-7 Shielded VNTC (TC-ER)

• Exposed Run (TC-ER) Rated: This cable has passed the rigorous UL 1277 crush and impact tests. Per NEC 336.10, it can extend from the cable tray to the equipment for up to 6 feet without continuous support or conduit, reducing material costs and installation time.

• EMI/RFI Suppression: The overall aluminum foil-polyester tape shield with 100% coverage, paired with a tinned copper drain wire, ensures signal integrity by blocking electrical noise from surrounding power cables and high-frequency equipment.

• Heavy-Duty Construction: 12 AWG stranded copper conductors offer higher ampacity and physical durability than standard control gauges, making this cable ideal for long industrial runs where voltage drop is a concern.

• Industrial Durability: Featuring THHN/THWN-2 insulation and a flame-retardant, sunlight-resistant PVC jacket, this cable is resistant to moisture, heat, and oils. It is approved for direct burial and use in Class I, Division 2 hazardous locations.

Common Applications

• Complex Control Circuits: Ideal for connecting control panels to multiple remote sensors, actuators, and solenoids in a single shielded run.

• Motor Control Centers (MCCs): Used for auxiliary control and monitoring circuits where signals must be protected from the high-noise environment of motor leads.

• Petrochemical & Utility Infrastructure: Suitable for telemetry and instrumentation in harsh environments where chemical resistance and signal clarity are paramount.

• Automated Manufacturing: Efficiently bundles multiple 120V or 24V control lines into a single, high-strength cable assembly.

Technical Note: To ensure the shield functions as intended, the tinned copper drain wire should be properly terminated to a ground bus at the source end only to prevent ground loops. When utilizing the TC-ER rating for exposed runs, ensure the cable is secured and protected from physical damage in accordance with local electrical codes.
