Line post insulator polymer

Line post insulator polymer is composed of insulation core rod, silicone rubber housing and insulator end fittings with good mechanical and electrical properties.

Line post insulator polymer

The function of insulators structure
1. Fiber glass core rod:
It is the skeleton of composite insulators, plays a supporting silicone rubber housing, internal insulation, coupling fittings at both ends, and withstand the mechanical load multiple roles, with high tensile strength.

The features of Fiber glass core rod
◆ High mechanical strength
◆ Good dielectric properties
◆ Chemical resistance
◆ God resistance to bending fatigue
◆ Creep and impact resistance

2. Polymer housing
Its main function is protecting the fiberglass rod, block rain and snow, increasing the creepage distances and the role of external insulation products.

Polymer housing is made from silicone rubber, flame retardants, anti-aging agents and fillers made by high temperature and pressure coupling vulcanization.

The features of Polymer housing
◆ Good hydrophobicity and migration
◆ Good corrosion resistance
◆ Anti-aging resistance
◆ Electrical insulating properties

The end fittings of Line post insulator polymer is made from steel or iron, should be hot dip galvanized and playing an important role of connecting insulators and conductors.
