Property Specification
Type: Composite Line Post Insulator
Features: Featuring a robust three-part assembly—a high-strength fiberglass epoxy resin core rod, a seamless silicone rubber weather housing, and galvanized metal end fittings—this insulator is engineered for long-term electrical reliability without the risk of puncture or zero-value failure. The outer silicone sheds are manufactured using a single-piece injection molding process to eliminate internal interfaces and prevent electrical breakdown. Built using high-precision crimping technology and quality-checked via automated ultrasonic flaw detection, the assembly offers superior mechanical strength in a compact, lightweight design. The corrosion-resistant hardware allows easy, direct interchangeability with legacy ceramic line post units.
