Wholesale Electric Barbed Wire Fence Supplier
Electric barbed wire fences combine a conductive high‑tensile steel wire with periodic barbs and an energizer that delivers controlled voltage pulses. The system provides both physical deterrence and an electric shock barrier, suitable for perimeter security where unauthorized intrusion must be detected and discouraged.
Technical Specifications
| Parameter | Typical Value | Unit |
|---|---|---|
| Wire core tensile strength | 1,600 | MPa |
| Zinc coating weight (galvanized) | 275 | g/m² |
| Barb spacing | 75–100 | mm |
| Energizer output voltage (peak) | 8,000 | V |
| Pulse energy | 0.5–1.0 | J |
| Maximum recommended fence length per energizer | 500 | m |
Materials & Construction
The conductive wire is manufactured from low‑carbon steel rod, cold‑drawn to achieve the required tensile strength, then hot‑dip galvanized to a minimum coating weight of 220 g/m² for corrosion resistance in outdoor environments. Barbs are formed by twisting two lengths of wire around the core at specified intervals, creating sharp protrusions that increase mechanical resistance to cutting. Insulators, typically UV‑stabilized polypropylene, are spaced every 3 m to prevent leakage current to ground posts.
Applications
- Perimeter security for agricultural livestock containment where predators pose a threat.
- Industrial facility boundaries requiring both visual deterrent and non‑lethal incapacitation.
- Correctional facility perimeters where low‑maintenance, high‑visibility barriers are mandated.
- Data center and substation fencing where tamper detection must trigger alarm systems.
Quality Assurance
Each production lot undergoes tensile testing on a sample length of wire to verify that the ultimate strength exceeds 1,500 MPa. Coating thickness is measured by magnetic induction on ten random specimens per batch, with acceptance criteria of ≥220 g/m² zinc. Insulators are subjected to a 1,000‑hour UV exposure test per ASTM G154, retaining >90 % of original dielectric strength. Finished fence rolls are inspected for barb uniformity, with a maximum allowable deviation of ±5 mm from the nominal spacing.
Customization Options
Customers may specify alternative wire diameters (2.0 mm to 2.8 mm) to adjust tensile strength and weight, select PVC‑coated wire for additional corrosion protection in marine atmospheres, or request customized barb geometry (length 15–25 mm, angle 30°–45°). Energizer compatibility can be tailored for solar‑powered units delivering 0.2 J pulses for low‑power sites, or mains‑operated units up to 5 J for high‑risk installations.
Packaging & Shipping
Fence rolls are wound on corrugated cardboard cores with inner diameter 150 mm, outer diameter not exceeding 300 mm, and secured with polyethylene stretch film. Each roll is labeled with length, wire gauge, coating class, and batch number. For export, rolls are placed in ISPM‑15 compliant wooden pallets, wrapped in water‑resistant barrier film, and secured with steel straps to withstand containerized handling.
Lead Time
Standard configurations (2.5 mm galvanized wire, 75 mm barb spacing) are available from stock with a dispatch time of 3–5 business days after order confirmation. Customized specifications require production scheduling, typically resulting in a lead time of 10–18 business days, depending on raw material availability and coating line capacity.
FAQ
- Can the fence height be adjusted? Yes, posts and insulators can be supplied for heights ranging from 1.2 m to 2.4 m; the wire length is cut to suit the selected height plus required tension margins.
- What information is needed for a quotation? Required details include total fence length, desired wire diameter, coating type (galvanized or PVC), barb spacing, energizer type (solar or mains), and any special packaging or labeling requests.
- How is the electric system tested before shipment? Each energizer is factory‑tested for output voltage and pulse energy into a 500 Ω load test fence, with results documented in the test certificate accompanying the order.
- Are spare parts available? Spare insulators, tensioners, and connector clips are stocked and can be shipped separately upon request.
- What certifications apply to the materials? The steel wire meets ASTM A641 for zinc‑coated steel; insulators comply with UL 94 V‑0 flame‑rating.
