Composite Suspension Insulator Uses, Structure and Performance

·Application of Composite Insulator

Composite Insulator is Especially suitable for dirty areas, high mechanical tensile loads, large spans, and compact lines. It has lightweight, small size, not easy to break, bending, high torsional strength, and strong explosion-proof.

·Product structure of composite suspension insulator

It consists of a glass fiber epoxy resin pull rod, silicon rubber umbrella skirt, and fittings. The silicon rubber umbrella skirt adopts the overall pressure injection process, thereby solving the key problem that affects the reliability of the composite insulator-interface electrical breakdown. The connection between the glass drawing rod and the metal fittings adopts a good crimping process. It is equipped with an automatic sonic flaw detection system. It has high strength, beautiful appearance, small size, lightweight, and the metal fittings are galvanized to prevent corrosion. Use, the structure of this product is reliable, does not damage the core rod, and can fully exert its mechanical strength.

Composite Insulator

· Composite Insulators product performance

· The electrical performance is superior, the mechanical strength is high, the internal bending strength of the epoxy glass fiber pull-out rod is 2 times higher than that of ordinary steel, and 8-10 times that of high-strength ceramic materials, which effectively improves the reliability of safe operation.

· Good anti-pollution performance, strong anti-pollution flashover capability, its wet withstand voltage and pollution withstand voltage are 2~2.5 times of the same creepage porcelain insulators, and it does not need to be cleaned, and can operate safely in heavily polluted areas.

· Small size and lightweight (only 1/6-1/9 of porcelain insulator of the same voltage level), light and compact structure, easy to transport and install.

· The silicone rubber umbrella skirt has good water-repellent performance, and its overall structure ensures that the inner insulation is not damp, no need for preventive insulation monitoring test, no cleaning, reducing the daily maintenance workload.

· Good sealing performance, strong resistance to electric corrosion, umbrella skirt material has resistance to tracking and leakage up to TMA4.5 level, has good aging resistance, corrosion resistance, low-temperature resistance, can be applied to -40 ℃ ~ +5 ℃ area.

· Has strong impact resistance and shock resistance, its good anti-brittleness and creep resistance, not easy to break, bending, torsion strength, can withstand internal pressure, strong explosion-proof force, can interact with porcelain and glass insulators Change to use.

· The composite insulator series products are superior to porcelain insulators in mechanical and electrical properties and have a large operating safety margin. They are newer products for power lines.
