Disc insulators also known as suspension insulators are the most widely used models for transmission and distribution lines.
The flexible but positive ball and socket connection provides a quick and easy coupling of insulators and are provided with R Clips or W Clips to prevent uncoupling of an insulator string. Our ball and socket arrangements confirm to IEC, ANSI, BS and other international standards.
OTDS disc insulators have a fine resiliant bitumen coating on the inside cap and the surface of the ball pin with cement to absorb stresses from thermal expansion.

- Smooth rounded contours of the shell provide protection against chipping
- Caps are made of malleable cast iron and pins of porged steel.
- These are galvanised to provide better protection against corrosion. The glaze applied is compressive in nature and formulated to provide a smooth surface for self cleaning.
- In strings they can be used for any voltage depending on the number of units mounted in a series.
- High and Medium voltgae lines up to system voltages of 132kV.
- Polluted envioronments
