FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why can't standard 600/1000 V PVC electrical wire be used as an underground electric fence lead-out cable?
Electric fence energizers deliver 8,000 V to 15,000 V pulses. Standard PVC insulation has a high dielectric constant (ε_r ≈ 6–8) that capacitively drains the short 100 µs pulse to wet soil, and 10 kV impulses rapidly carbon-track and puncture 0.8 mm PVC walls, grounding out the entire fence.
When should I choose AH-UC2.5 (Ø 2.5 mm) over AH-UC1.6 (Ø 1.6 mm)?
AH-UC1.6 (2.01 mm² galvanized steel, ~85 Ω/km) is suitable for short domestic security lead-outs under 50–100 m. For longer lead-out runs (> 100 m), multiple under-gate jumpers in series, or high-joule livestock/game energizers, AH-UC2.5 (4.91 mm², ~35 Ω/km) or aluminum-core AH-UC2.5-AL (~7 Ω/km) reduces pulse voltage drop by more than 60 %.
Why is a galvanized steel or aluminum conductor often preferred over bare copper on electric fences?
Fence line wires are predominantly galvanized steel or aluminum alloy. Clamping bare copper directly to galvanized steel in wet outdoor air creates an electrolytic cell that rapidly corrodes the zinc and causes high-resistance arcing joints that generate radio interference.
What factory routine tests and certificates are supplied with Nemtek AH-UC1.6 / AH-UC2.5?
Every production drum of Nemtek AH-UC1.6 / AH-UC2.5 undergoes 100 % conductor DC resistance measurement at 20 °C, high-voltage AC/DC dielectric withstand testing, and dimensional verification per IEC 60335-2-76 / EN 60335-2-76 / SANS 10222-3 / AS/NZS 3014, supplied with an EN 10204 3.1 inspection certificate.
