Epoxy Resin MV Post Insulator | 12 kV Switchgear Busbar Support, APG Cast
Indoor cast-resin support insulator, high creepage, 4-12.5 kN
$8.00
Overview
Indoor medium-voltage post (support) insulators are APG/vacuum cast in cycloaliphatic epoxy resin and used to support busbars and live parts inside MV switchgear, circuit breakers and disconnectors. The ribbed shed profile gives long creepage distance, high mechanical strength and excellent arc and moisture resistance.
Key Features
High-grade epoxy resin, APG pressure-gel / vacuum cast
Long creepage path with ribbed sheds for pollution performance
High cantilever (bending) mechanical strength
Low partial discharge, stable dielectric performance
Threaded brass inserts for direct busbar mounting
Compact, maintenance-free indoor construction
