As a main polymer pin insulator, 11KV pin type composite insulators are manufactured in accordance with IEC 120, ISO 140, IEC 1109, and so on, and are widely used in many countries.

It shall be the responsibility of the pin insulator manufacturer to ensure adequacy of the design and good engineering practice in the manufacture of the 11KV pin type composite insulators. The manufacturer, Orient Power meets standards which confirm satisfactory service experience with polymer pin insulator products.

These standards are for 11KV pin type composite insulators for use on overhead power lines:
IEC 120: Dimensions of end fittings of polymer pin insulators units.
IEC 815: Guide for the selection of insulators in respect of polluted conditions.
ISO 1461: Metallic Coatings – Hot dip galvanized coatings on fabricated ferrous products – Requirements.
ISO 1460: Metallic Coatings – Hot dip galvanized coatings on fabricated ferrous metals – Determination of mass per unit area – Gravimetric method.
IEC 1109: 11KV composite pin type insulators for a.c. overhead lines – Definitions, test methods and acceptance criteria.

11KV pin type composite insulators of the Orient Power have been installing for a long time, namely since 1978, in many Countries both on MV and HV lines.
