Composite tie top pin insulators consist of FRP core, silicone rubber housing and shed and insulator end fittings.

Composite tie top pin insulators are used on overhead distribution lines consisting of porcelain units and insulator pin. Composite tie top pin insulators are made from silicone rubber materials.

Composite tie top pin insulators are usually used up to 35kV power lines. Composite tie top pin insulators can be divided into
◆ Long spindle pin insulator
◆ Short spindle pin insulator

Composite tie top pin insulators usage:
◆ Long spindle used on wooden cross arms
◆ Short spindle used on iron cross arm

FRP core is an important part of Composite tie top pin insulators, it is necessary that permissible bending load is not exceeded either during laying or in later service.

End fittings of composite tie top pin insulators connect lines and insulators which is one main part of insulators made from steel, iron or stainless steel.
