What is Poly Wire?
Poly wire is a flexible wire option for electric fencing composed of steel conductors encased in synthetic polymer (polyethylene or polypropylene). It delivers low-resistance conductive paths while being lightweight and weather-resistant. Industrial and agricultural professionals choose poly wire for durable electric fencing and may select variants such as 2 mm polywire or versions with stainless steel conductors.
Products You’ll Find in This Category
This category contains poly wire products in various diameters, colors, conductor configurations, and package sizes. You’ll see polywire with thicknesses of about 2 mm, 3 mm, and 3.5 mm. Wire colors include black, orange, white, green, and combinations such as white-&-green or black-&-white. Package lengths range from shorter 100-meter rolls to longer rolls at 250 m, 500 m, and up to 1000 m in some cases. Conductors are often multi-strand stainless steel wires embedded in the polymer outer material.
Applications & Industry Use Cases
Poly wire is used primarily in livestock containment, permanent and temporary electric fencing, rotational grazing systems, and boundary delineation. Factors such as electric fence wire resistance and fencing conductor stainless steel are relevant when assessing performance. These products are applied in pasture management, wildlife control, enclosure of sensitive areas, and farm subdivisions. Environments include exposed outdoor settings, wet or damp conditions, and locations requiring visible markers (colors) for safety and ease of maintenance.
Technical Guide to Poly Wire
Poly wire is designed to combine conductive metal core strength with outer polymer insulation. Key technical characteristics include diameter (nominal wire thickness), breaking strength (tensile load before failure), electrical resistance per meter, number of metal strands (conductors), and material of conductors (typically stainless steel). For example, a 2 mm wire may have 3 stainless steel conductors and a breaking strength around 40-55 kg; a thicker 3.5 mm wire could bear up to about 160 kg. Resistance is inversely related to conductor cross-section: lower resistance per meter results when multiple strands are used.
Variations include wire thicknesses—2 mm for lighter loads or shorter spans; 3-3.5 mm for heavier duties or longer run lengths. Wire color can signal visibility and integration into landscape. Wire resistance and conductor combination affect how evenly voltage is maintained over distance. CE marking is noted for compliance in European markets; conformity to standards governing electrical safety and materials is relevant. Considerations when selecting poly wire include environmental exposure (UV, moisture, temperature), required voltage retention, animal behavior (bite, rubbing), and compatibility with energisers and insulators.

Frequently Asked Questions about Poly Wire
- What does the diameter of poly wire signify?
- The diameter refers to the nominal thickness of the wire, including its polymer outer layer. Larger diameters (e.g., 3-3.5 mm) typically provide higher tensile strength and more room for conductors, resulting in lower electrical resistance and greater mechanical durability.
- How many conductors are inside poly wire?
- Poly wire usually contains multiple stranded stainless steel conductors—commonly three strands in thinner wires and more in thicker wires. The number and cross-section of conductors determine current carrying capacity and resistance per meter.
- What is breaking strength of poly wire?
- Breaking strength is the load at which the wire fails under tension. For example, a 2 mm poly wire may have breaking strength around 40-55 kg, whereas thicker materials like 3.5 mm may reach approx. 160 kg. This spec impacts performance across spans and under stress.
- What resistance should buyers expect per meter?
- Resistance per meter depends on conductor design and length. In thinner poly wire of about 2 mm, you might see resistance values near 0.19 ohm/meter. Thicker multi-strand versions may show lower resistance per meter, such as around 0.37 ohm/meter, depending on conductor material and count.
- Which standards or markings relate to poly wire compliance?
- Compliances include CE marking, which indicates conformance with European safety standards and material regulations. Material properties like resistance, tensile strength, conductor composition (e.g., stainless steel), and insulation (polymer type) are often specified to meet regulatory and performance expectations.
