CYM-INSIST electric fence feeder wire 12.5 gauge 328 ft — double-insulated, direct-burial, 20 kV capacity

CYM-INSIST 12.5 gauge 328 ft double-insulated wire is a direct-burial, high-voltage feeder cable designed to reliably connect your fence charger to the fence line or run under gates with minimal voltage loss.

This heavy-duty underground electric fence cable pairs a 2.5 mm aluminum conductor with dual PE insulation to deliver up to 20 kV over long runs while resisting moisture, abrasion, and soil conditions. Supplied on a 328-foot spool, the single-core high-voltage cable is optimized for permanent installations, under-gate routing, and standard hook-ups where a durable, low-resistance feed is required. The kit includes installation accessories—split-bolt connectors and protective gloves—to get you started safely and quickly.

How does this wire reduce voltage loss on long runs?

The wire uses a 2.5 mm aluminum core with a low resistance (about 2.5 ohms per 100 m) and two layers of polyethylene insulation to protect against moisture and leakage. That combination keeps high-voltage pulses strong over hundreds of feet and helps maintain effective fence performance even when buried directly in soil.

• 2.5 mm aluminum conductor for low electrical resistance
• Double PE insulation minimizes leakage and moisture ingress
• Rated to carry up to 20 kV for long-distance feed lines
• Designed for direct burial and under-gate routing

Is this cable easy to install under gates and in permanent runs?

Yes — the single-core, flexible construction and 328 ft spool format simplify routing through gates and along fence lines. The cable is suited for direct burial so you can run it under gates or trench it along permanent fences without special conduit in most situations.

• Flexible single-core wire for easy threading under gates
• Direct-burial rated to avoid extra conduit in many installations
• Comes with split-bolt connectors for secure splice points
• Includes gloves for safer handling during connection

What safety and durability features does the product include?

Double polyethylene insulation shields the aluminum core from water, abrasion, and soil chemicals, extending service life and reducing shorting risk. Accessories in the package help you make reliable, secure connections while protecting your hands from sharp strands and high-voltage components during setup.

• Dual PE jacket resists moisture and mechanical damage
• Aluminum core balances conductivity with corrosion resistance
• Split-bolt connectors provide robust electrical joins
• Protective gloves included to reduce handling risk

Will this wire work with my existing fence charger and fence type?

It’s compatible with most agricultural and livestock fence chargers that require a high-voltage feed line; the conductor and insulation are sized for standard fence hookups and under-gate cabling. Verify your charger’s recommended cable types and voltage ratings, but this cable is engineered to handle up to 20 kV and long-distance runs without excessive loss.

• Suitable for chargers that output up to 20 kV
• Standard hookup and under-gate applications supported
• Works well for electrified livestock and boundary fences
• Check charger manual for specific conductor recommendations

Who is this for? Farmers, ranchers, and property owners who need a robust, low-resistance underground feed cable will appreciate this CYM-INSIST offering. It’s aimed at installers and DIYers who want a dependable, direct-burial cable for under-gate runs, permanent fence lines, and long-distance charger connections—especially where moisture resistance and minimal voltage loss matter. The included connectors and gloves make it a convenient choice for first-time installs or repairs.
