Overview
The Burndy Hyplug AYP0 series comprises aluminum compression adapters engineered for secure termination of aluminum and copper conductors in mechanical connector applications. This lot includes two units in sizes AYP0250, AYP0300, and AYP0350, designed to eliminate bi-metallic corrosion through all-aluminum, electro-tin-plated construction. Each adapter arrives factory sealed with Penetrox oxide-inhibiting compound and matching EPDM rubber cover rated for 600 VAC.
Key Features
- All-aluminum, electro-tin-plated design eliminates bi-metallic corrosion risk
- Factory prefilled with Penetrox compound containing conductive metallic particles for air-tight, low-impedance connections
- EPDM rubber covers supplied and rated for 600 VAC, eliminating need for tape
- Compact offset pin design permits installation in equipment with limited working space
- Solid electro-tin-plated aluminum plug provides smooth contact surface for superior electrical conductivity
- Five die sets cover wire range from 6 AWG to 750 kcmil, reducing inventory requirements
