Pw-15-Y/432 Pin-Type Insulator Porcelain Key Features
Superior Electrical Performance – The Pw-15-Y/432 insulator delivers reliable electrical performance for 15kV systems, with a total creepage distance of 432 mm that effectively increases leakage distance and reduces the risk of pollution flashover, guaranteeing safe operation of 15kV lines even under rain, fog, and contaminated conditions.
High Mechanical Strength – With a cantilever strength of 11 kN (2,400 lbs), the insulator reliably withstands conductor tension, wind loads, and ice accretion, ensuring long‑term stability in overhead line installations.
Excellent Anti‑Pollution Flashover Performance – The protected creepage distance of 197 mm and total creepage of 432 mm effectively increase leakage distance, reduce the risk of pollution flashover, and ensure reliable operation across various contamination levels.
Simple Structure, Easy Installation – The pin‑type insulator features a one-piece porcelain body designed for convenient mounting on standard pins. The conductor is secured in the groove or on the neck of the insulator using standard binding methods.
Glazed Porcelain Finish – The insulator features a durable glaze coating (available in brown, grey, or white) that provides excellent weather resistance, UV protection, and self-cleaning properties, ensuring long-term performance in harsh outdoor environments.
Reliable Design – Engineered for long-term reliable operation with minimal maintenance requirements – regular visual inspections and cleaning are typically sufficient to ensure continued performance.
