1130W/32 Pin-Type Insulators Porcelain – Key Features
Superior Electrical Performance – The 1130W/32 insulator delivers reliable electrical performance for 11kV systems, with a nominal minimum creepage distance of 250 mm that effectively increases leakage distance and reduces the risk of pollution flashover.
Testing and verification follow AS/NZS 2947.1 – Test methods for insulator units, guaranteeing safe operation of 11kV lines even under rain, fog, and contaminated conditions.
High Mechanical Strength – With a minimum bending failing load of 11 kN, the insulator reliably withstands conductor tension, wind loads, and ice accretion, ensuring long-term stability in overhead line installations. For installation best practices, refer to our Insulator installation guide for 11kV overhead lines.
Semi-Conductive & Unglazed Design – The drawing specifies a “semi-conductive” and “No Glazed” surface. This specialized finish is designed to optimize pollution performance and reduce radio interference in heavily contaminated environments.
Research on semi-conducting glaze insulator performance demonstrates that semi-conductive glazed insulators exhibit higher flashover voltages under contaminated and wet conditions compared with conventional porcelain insulators.
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 side groove or on the neck of the insulator using standard binding methods.
Reliable Design – Engineered for long-term reliable operation with minimal maintenance requirements – regular visual inspections and cleaning are typically sufficient to ensure continued performance.
