FXBW4 Series Composite Post Insulators High-Strength & Corrosion-Resistant
As a core electrical component in high-voltage power transmission and distribution systems, the FXBW4 series composite post insulators from Weisho Electric Co., Ltd. have become a reliable pillar of the power grid. They fulfill the dual role of supporting conductors and providing dependable insulation, making them an indispensable part of the electrical infrastructure used across power transmission and distribution networks.
Core Technology & Performance, Verified by Data




The outstanding performance of our insulators stems from a sophisticated combination of structure and materials. The insulating core rod, made from aerospace-grade epoxy resin fiberglass, provides high tensile strength for structural stability. The shed, crafted from innovative silicone rubber, offers excellent hydrophobicity and corrosion resistance, providing long-lasting protection for the insulator.
This design gives the FXBW4 series a range of powerful performance advantages:
Superior Mechanical Strength: Our products can withstand a rated mechanical load of up to 120KN, exceeding industry standards. This ensures safe and stable operation even in extreme weather conditions and under heavy loads.
Exceptional Electrical Performance: High-quality insulating materials provide reliable electrical isolation, effectively preventing current leakage and maintaining the stability of the entire electrical system.
High Contaminant Flashover Resistance: The excellent hydrophobic properties and long creepage distance of the silicone rubber shed allow our insulators to operate reliably in humid and polluted environments, significantly reducing maintenance costs.
Here are the detailed technical parameters for the FXBW4 series insulators. The data speaks for itself.
