CYM-INSIST 12.5 Gauge 82ft Underground Electric Fence Wire — 2.5mm Aluminum Core, Double PE Insulation

CYM-INSIST 12.5 gauge 82ft double-insulated underground wire is a direct-burial high-voltage cable designed to connect your energizer to the fence line or run beneath gates while minimizing voltage loss.

This heavy-duty underground cable combines a 2.5 mm aluminum core with double PE insulation to deliver reliable high-voltage performance for agricultural and perimeter electric fences. Built for direct burial and gate crossings, the wire is engineered to carry up to 20 kV over long runs with low resistance, reducing energy loss and preserving charger output so your fence performs as intended. The package also includes two split-bolt connectors and a pair of gloves to help with a safer, ready-to-install setup.

How does this underground wire keep voltage loss to a minimum?

The CYM-INSIST wire uses a 2.5 mm aluminum conductor with a resistance of about 2.5 ohms per 100 m and two layers of polyethylene insulation. The thicker conductor and dual insulation reduce leakage and prevent moisture intrusion, helping more of the charger’s output reach the fence line instead of dissipating in the ground.

• 2.5 mm aluminum core for low electrical resistance
• Double PE insulation to block moisture and reduce dielectric loss
• Rated to supply up to 20 kV for long-distance runs
• Specifically intended for direct burial and under-gate routing

Can I use this cable under gates and in permanent trenching?

Yes — the cable is designed for direct burial and under-gate installations where the energizer sits away from the fence line. Its rugged double-insulated jacket withstands contact with soil and typical gate movements without exposing the conductor.

• Direct-burial rated for permanent underground placement
• Sized for under-gate runs and standard charger-to-fence connections
• Durable PE jacket resists abrasion and environmental stress

What comes in the box and what should I expect during installation?

The product arrives as an 82-foot spool of single-core high-voltage cable with two split-bolt connectors for secure conductor joins and a pair of installation gloves. The gloves are included for safer handling; their color may vary. Installation requires basic fence tools and standard connector methods for high-voltage fencing.

• 82 feet of 12.5 gauge (2.5 mm) single-core cable
• Two split-bolt connectors for reliable splices
• One pair of gloves (color may differ from photos)
• Suitable for standard hook-up wiring and repairs

How compatible is this wire with common fence chargers and fence types?

The low-resistance aluminum core and 20 kV rating make the cable compatible with most agricultural and perimeter energizers that output high voltage. It works well for both new installations and repairs where an underground or under-gate connection is required, as long as connectors and installation practices match the charger specifications.

• Works with chargers designed for up to 20,000 volts
• Sized to minimize loss over distances exceeding 100 meters when used in proper configurations
• Ideal for farmland, paddock boundaries, and residential perimeter fences

Who is this for?

This CYM-INSIST double-insulated underground cable is aimed at farmers, livestock keepers, ranch hands, and property owners who need a durable, low-resistance connection between a fence energizer and the fence line — especially where lines must pass under gates or be permanently buried. It’s also suitable for maintenance crews and installers who want a ready-to-use kit including connectors and gloves for faster, safer splicing and hookup.
