The ZJ series 12kV post insulators are designed to ensure stable electrical insulation and mechanical support in medium-voltage systems. Manufactured from high-quality epoxy resin, they provide superior dielectric strength, long creepage distances, and excellent resistance to electrical and environmental stress.
With a variety of diameters and heights available, these insulators are suitable for multiple installation needs. Their compact and rugged design allows for reliable operation even in demanding environments, making them ideal for switchgear and other electrical equipment.
