Product Description

Product Overview

Disc-type suspension insulators, often referred to as disc insulators, are used in AC overhead power lines, substations, and electrified railway catenary systems with rated voltages exceeding 1000 V and frequencies not exceeding 100 Hz, serving as insulating and supporting elements. Due to their structural characteristics, these insulators exhibit superior electromechanical strength. Moreover, by connecting multiple units in series, it is possible to obtain insulator strings that meet the required voltage levels; consequently, they are widely employed on high‑voltage, extra‑high‑voltage, and ultra‑high‑voltage transmission lines, making them essential line insulators. Disc insulators are typically operated in string configurations; therefore, individual insulator units do not have a fixed rated voltage but are classified according to their electromechanical breaking load into grades of 40, 70, 100, 120, 160, and 210 kN.

Disc-type suspension insulators are assembled by cementing an iron cap, an insulating body (case), and a steel foot together using a cementitious adhesive. Depending on application requirements, they are classified into two types: ball‑and‑socket connections and groove‑type connections, and are available in voltage ratings of 240 kV, 300 kV, 420 kV (400 kV), and 550 kV (530 kV).

Disc-type suspension insulators are mainly classified into three major types: standard, bell‑shaped, and aerodynamic. The aerodynamic type is further subdivided into single‑shed, double‑shed, and triple‑shed configurations.
