FSZW2 Series Power Post Insulator – Reliable Support for High Voltage Switchgear

High-Strength Epoxy Resin Core for Indoor & Outdoor HV Applications

The FSZW2 series power post insulator is a robust, solid-core insulating unit used primarily in 35kV class power equipment, including high-voltage switchgear, isolators, and busbar supports. Made of high-strength epoxy resin with embedded metal inserts, this insulator provides excellent mechanical and dielectric performance in compact substation environments.

Compliant with IEC 60273 and GB/T 10068, FSZW2 insulators are commonly deployed across power plants, utilities, renewable energy projects, and industrial substations in both indoor and outdoor setups.

❓ FAQs

• Is FSZW2 suitable for outdoor use?
Yes, the epoxy surface is UV-resistant and water-sealed for outdoor exposure.

• Can I use this on a 33kV isolator?
Absolutely. FSZW2 is rated up to 35kV with ample impulse withstand margins.

• Do you provide different mounting types?
Yes. Threaded flange, flat base, and custom inserts are all available.

• What’s the lifespan?
Over 25 years in most service conditions with zero maintenance.

• Is routine testing required?
Only visual inspection is typically needed. Full type test reports are included on delivery.
