What is suspension insulators

Suspension insulators are a common type of insulator in the industry and are commonly used in output circuits and wiring systems. They are designed to support wires or cables and provide electrical insulators between the cable and the supporting structure. Usually made of insulating materials (such as ceramics or polymers), they can withstand the voltage and environmental effects in the power system and ensure the safe operation of electrical equipment and lines.

The disadvantages of suspension insulators

 Heavy weight: Because they are often made from ceramic or composite materials, suspension insulators tend to be heavy, which increases the complexity and cost of installation and maintenance.

Vulnerable to damage: Suspension insulators are easily affected by external shock or vibration during transportation and installation, resulting in breakage or damage.

Difficult maintenance: Because they are often installed at high altitudes or in hard-to-reach locations, maintaining and replacing suspension insulators requires special tools and techniques and may require power outage operations.

Higher cost: Due to the complexity of materials and manufacturing processes, the cost of suspension insulators is relatively high, especially for large power systems.

Summary

Although suspension insulators play an important role in power systems, they also present some challenges and limitations in terms of installation, maintenance and economic costs.
