Glass disc insulator
What It Is A glass disc insulator consists of a tempered glass “doughnut” with a metal cap and pin. Discs are strung together into “insulator strings” to achieve the required voltage withstand. Their transparency and mechanical strength make them a trusted choice on overhead lines worldwide. Core Features Technical Snapshot Parameter Specification Voltage Class 69 – 500 kV…

Porcelain Insulator
Porcelain Post insulators—also called line post insulators or station post insulators—are high-voltage (HV) devices engineered to IEC, ANSI and other international standards for power systems up to 1 100 kV. Typically molded as a single-piece pillar from either high-strength porcelain or advanced composite materials (silicone rubber), they combine excellent mechanical strength, weather resistance and long-term reliability.
In overhead distribution and transmission networks, line post insulators secure conductors in place of traditional pin insulators for voltages up to 69 kV. Five common designs meet diverse mounting and load requirements:
-
Bollard top line post
-
Vertical clip-on top line post
-
Horizontal (stud-mounted) clip-on top line post
-
Horizontal (gain-base) line post
-
Support post insulator
Each variant features a specialized clamp unit that grips the conductor—either vertically or horizontally—ensuring stable insulation under mechanical stress.
Within substations and switchyards, station post insulators are installed vertically to support and insulate transformers, switchgear and busbars. For extra-high voltage applications, multiple post insulators can be stacked into a composite assembly, effectively withstanding combined bending, compression and electrical stresses.
