AVBD 1200PRODUCT DATA
ENC Security Fence: Non Conductive FRP Fencing for Substations and Energized Yards
ELECTRICALLY NON-CONDUCTIVE FRP PERIMETER SYSTEM
A security fence that carries no current, corrodes in no climate, and lets radar and radio pass through it. Every production batch is flash-over tested to a minimum of 138,000 volts. Forced-entry tested to ASTM F2781-15.

THE CASE FOR NON-CONDUCTIVE
STEEL IS A CONDUCTOR. THAT'S THE PROBLEM.
Inside a substation fence line, a steel fence becomes part of the electrical environment and must be bonded, grounded and inspected. An FRP fence is not part of that circuit. ENC uses non-conductive FRP posts and panels, with every production batch flash-over tested by a certified laboratory.
The system also carries independently measured forced-entry performance under ASTM F2781-15 and is engineered for project-specific wind loading.

Read any AVBD number the same way across the line: family, then threat rating, then configuration. AVBD 1200 is the ENC composite fence family (12), non-conductive rather than crash rated (0), base configuration (0).

Certified laboratories perform flash-over voltage testing on every production batch, to a minimum of 138,000 V; the brochure cites a maximum tested value of 650,000 V. Forced-entry testing was performed by Southwest Research Institute to ASTM F2781-15 at the aggressive threat level. Batch results and the SwRI report are available for submittal.
