Property Specification
Type: Composite Polymer Pin Insulator
Features: Serving as a foundational design in high-voltage distribution and transmission, this rigid polymer pin insulator combines lightweight construction with cost-effective, straightforward installation. Engineered for 6 kV to 35 kV three-phase overhead power systems operating at frequencies up to 100 Hz, its vertical mounting configuration places the grounded hardware beneath the unit to optimize clearance and allow for lower structure profile heights. Comprising a high-strength steel support pin permanently integrated with single or multi-component composite insulation sections, it provides dependable structural support and phase isolation in both standard and heavily contaminated environments.
