EH-24 Pin-Type Porcelain Insulator Key Features
Superior Electrical Performance – The EH-24 insulator delivers reliable electrical performance for 24kV systems, with a creepage distance of 310 mm that effectively increases leakage distance and reduces the risk of pollution flashover, guaranteeing safe operation of 24kV lines even under rain, fog, and contaminated conditions.
High Mechanical Strength – With a minimum cantilever failing load of 13kN, 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 creepage distance of 310 mm effectively increases leakage distance, reduces the risk of pollution flashover, and is suitable for 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 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, suitable for both urban and rural distribution networks.
