Polymer dead end insulator,polymer dead end insulator 69kV

Polymer dead end insulator 69KV was introduced in the late sixties. The basic idea consists of the combination of different materials, which perform different duties in the insulator function corresponding to their particular strength and properties.

Polymer dead end insulator consists of silicone rubber housing, shed, end fittings and fiber glass reinforced core rod. The end fittings are typically made of metal, such as forged steel or aluminum. For polymer dead end insulators, a high degree of standardization has been achieved for the end fittings, which enables the easy replacement of existing conventional insulators by composite solutions.

The fiber glass reinforced core rod is responsible for bearing the mechanical loads, which can be tension, bending or compression, or a combination of all three, depending on the application and load scenario.

Materials for the housing are as manifold as the corresponding methods of manufacturing. However, there are performance trends as a result of the existing service experience, details of which are provided later. Today these polymer suspenison insulators made of high-grade synthetic materials have exhibited outstanding mechanical and electrical characteristics, and have exceeded all overhead line and switch gear engineering applications in worldwide.
