Detailed Description
What UL1185 Shielded Hookup Wire Solves in Equipment Wiring
UL1185 shielded hookup wire is a single-conductor, 300 V, 80 °C PVC-insulated lead built for internal equipment wiring where a tinned copper conductor and a metallic shield are both required. The shield is the defining part of this construction. It gives the circuit a return path for coupled noise and reduces EMI and crosstalk before they reach sensitive signal or audio stages. Typical uses include appliance internal wiring, LED driver output or control leads, control panel harnesses, and audio signal transmission inside AV and office automation equipment.
If your harness shop needs a UL AWM hookup wire that can be stripped and soldered, this construction uses stranded lead-free tinned copper. The tinning helps the strands stay together during cutting and stripping, so terminals and solder joints close at their published dimensions. The PVC insulation and PVC jacket are applied over the shield to hold the round profile and protect the shield during routing.
Construction Layer by Layer
The conductor is lead-free tinned copper, stranded to the per-size construction shown in the tables below. A PVC insulation wall separates the conductor from the shield. Around that, a tinned copper spiral (serve) shield is applied for 28 AWG to 10 AWG. For 8 AWG and larger sizes, the shield changes to a braided tinned copper construction. A PVC jacket is then extruded over the shield. This single-conductor shielded hookup wire is not a multi-conductor cable; each circuit uses one shielded lead.
The shield type follows the size break: spiral (serve) shield on 28 AWG to 10 AWG, braided shield on 8 AWG and larger. The spiral shield is made from multiple tinned copper strands served around the core, and the braided shield uses a woven tinned copper structure for the larger diameters. Both are metallic shields; they are intended to reduce EMI and crosstalk in equipment wiring.

The 80 °C rating is intended for equipment interiors where ambient and conductor temperatures stay within that limit. The 300 V rating covers the internal wiring needs of appliance, lighting, control panel, and data processing equipment. The VW-1 flame rating and RoHS/REACH compliance support builds that require restricted substances control and flame-rated PVC.
Where UL1185 Shielded Hookup Wire Is Used
UL1185 is used in appliance internal wiring, lighting fixtures, industrial machines, and heating products. In these assemblies, the single shielded conductor can be routed through a harness or panel without adding a separate shield. In LED driver and control panel wiring, the shield helps keep switching noise and coupled signals away from control lines. In AV electronics, office automation equipment, and data processing systems, it supports audio signal transmission and other low-level signal runs where EMI and crosstalk are concerns.
The construction also fits electronic devices that need an internal or external connection with a tinned copper conductor and a metallic shield. Because the shield is part of the cable, the lead can be used where a non-shielded hookup wire would pick up interference from nearby power or switching circuits.
Selection, Stripping, and Supply Options
Choose the AWG by the conductor structure in the tables above, not by the nominal area alone. For 28 AWG to 10 AWG, the shield is a spiral (serve) tinned copper layer. For 8 AWG and larger, the shield is braided. The stranded lead-free tinned copper conductor is designed for stripping and soldering in harness and panel shops, and the tinning helps keep strands together during termination.
The PVC insulation and PVC jacket are extruded over the shield to maintain a round profile. OD tolerance is ±0.20 mm, and conductor structure tolerance is ±0.01 mm. The standard jacket color is black, and custom colors include black, red, yellow, blue, green, white, gray, brown, orange, pink, purple, and dual colors. The core color is white on the listed reel sizes. Surface printing includes model, size, flame rating, temperature, and voltage markings.
Standard supply is 500 m reels for 28 AWG to 18 AWG and 300 m reels for 14 AWG. Cut lengths of 8 m (25 ft) and 32 m are also available. For equipment builders, these options allow one shielded hookup wire to be stocked in the sizes used across appliance, LED driver, control panel, and audio signal wiring.
Why This Shielded Hookup Wire Fits Your Equipment
For an OEM electrical design engineer, the key points are the 300 V and 80 °C ratings, the 28 AWG to 4/0 AWG range, and the shield break at 10 AWG. The single-conductor shielded construction solves the problem of running one signal or power lead through an EMI-sensitive area without switching to a multi-conductor cable. For a harness or panel shop, the tinned copper conductor supports stripping and soldering, while the PVC insulation and PVC jacket hold the cable shape during routing.
For maintenance and purchasing teams, UL1185 is produced to UL Subject 758 and UL62, carries a VW-1 flame rating, and complies with RoHS and REACH. It can be ordered in standard black or custom colors, on full reels or cut lengths. If your equipment uses a 300 V, 80 °C shielded hookup wire for appliance internal wiring, LED driver leads, control panel signals, or audio signal transmission, this construction is built to match that interface.
