SHF-35G Pin-Type Porcelain Insulator Key Features
Superior Electrical Performance – The SHF-35G insulator delivers a dry power frequency withstand voltage of 100 kV, wet power frequency withstand voltage of 85 kV, lightning impulse withstand voltage of 195 kV, and puncture voltage of 200 kV, guaranteeing safe and reliable operation of 35kV lines even under rain, fog, and lightning conditions.
High Mechanical Strength – With a minimum bending failing load of 15.6kN, 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 700mm effectively increases leakage distance, reduces the risk of pollution flashover, and is particularly suitable for industrial, desert, and coastal areas with high contamination levels.
Low Radio Interference – With a maximum RIV of 200μV at 1000 kHz (test voltage 44kV RMS to ground), the SHF-35G ensures minimal electromagnetic interference, making it ideal for installations near communication lines and sensitive electronic equipment.
Simple Structure, Easy Installation – The pin‑type insulator features a porcelain body and a steel pin (or threaded insert) cemented with high‑strength Portland cement. The top groove design facilitates convenient conductor placement and binding, reducing pole height and installation time.
Brown Glaze Finish – The insulator features a durable brown glaze that provides excellent weather resistance, UV protection, and self-cleaning properties, ensuring long-term performance in harsh outdoor environments.
