• Importansya: Kini nga katangian gihatagan sa silicone rubber ka effective sa high-humidity areas, coastal regions, salt fog environments, ug industrially polluted areas, naa gyud ni siya nga anti-flashover performance sa insulators.

2. Good Resistance to Tracking and Arcing

• Katangian: Ang silicone rubber adunay excellent resistance to tracking, maintaining surface integrity even after prolonged exposure to partial discharges. Adunay usab kini nga high resistance to arcing, allowing it to quickly recover its insulating properties after arc exposure.

• Importansya: Kini nag-siguro nga ang silicone rubber insulators makapuyo reliable over long periods in harsh environments, nag-reduce sa risk sa failures caused by tracking or arcing.

3. Superior Electrical Insulation Strength

• Katangian: Ang silicone rubber adunay high breakdown voltage ug good dielectric constant, providing reliable insulation performance under high-voltage conditions. Ang iyang volume resistivity adunay labi ka taas, effectively preventing current from passing through the material.

• Importansya: Ang silicone rubber insulators makapuyo stable electrical isolation in high-voltage transmission lines and substations, ensuring the safe operation of power systems.

4. Excellent Weather Resistance and Aging Resistance

• Katangian: Ang silicone rubber adunay taas nga resistance sa ultraviolet light, ozone, oxygen, ug uban pang environmental factors. Naka-maintain ang iyang performance without significant degradation even when exposed outdoors for extended periods. Additionally, adunay kini nga good chemical resistance, resisting corrosion from acids, alkalis, and salts.

• Importansya: Kini nag-siguro nga ang silicone rubber insulators naka-reliable ug naka-stable in various climatic conditions, extending their service life.

5. Wide Operating Temperature Range

• Katangian: Ang silicone rubber naka-maintain ang iyang physical ug electrical properties over a wide temperature range, typically from -60°C to +200°C. Wala kini nga mabrittle sa low temperatures o mawad-an sa high temperatures.

• Importansya: Kini nag-siguro nga ang silicone rubber insulators suitable for extreme cold or hot environments, such as polar regions or tropical areas, ensuring reliable performance under different climate conditions.

6. Good Elasticity and Mechanical Properties

• Katangian: Ang silicone rubber adunay excellent elasticity ug flexibility, allowing it to return to its original shape after being subjected to mechanical stress. Adunay usab kini nga high tear strength ug wear resistance, capable of withstanding mechanical impacts and friction.

• Importansya: Kini nag-siguro nga ang silicone rubber insulators naka-withstand significant mechanical loads during installation and operation, reducing the risk of damage due to external forces.

7. Self-Cleaning Properties

• Katangian: Tungod sa iyang hydrophobic surface ug smooth texture, wala kini nga madikit ang dust ug contaminants. Kahit na mayroon man mga contaminants na settle sa surface, naka-wash away sila ngadto sa ulan.

• Importansya: Kini nag-reduce sa need sa manual cleaning, lowering maintenance costs, ug helping maintain the insulator's good insulation performance.

8. Low Water Absorption

• Katangian: Ang silicone rubber adunay very low water absorption, meaning wala kini nga madugay sa significant amounts of moisture even in high-humidity environments. Kini nag-prevent sa decline sa electrical performance tungod sa moisture absorption.

• Importansya: Kini nag-siguro nga ang silicone rubber insulators naka-maintain ang good insulation performance in humid environments, reducing the risk of flashover caused by moisture.

9. Environmental Friendliness

• Katangian: Ang silicone rubber non-toxic ug environmentally friendly, meeting environmental standards. Wala kini nga mag-release og harmful substances during production or use, ug naka-dispose through incineration with minimal environmental impact.

• Importansya: Kini nag-siguro nga ang silicone rubber insulators mas aligned sa sustainable development requirements, leading to widespread adoption in modern society.

10. Ease of Processing and Molding

• Katangian: Ang silicone rubber adunay good flowability ug moldability, allowing it to be processed using various methods such as injection molding, extrusion, and compression molding. Naka-manufacture kini into complex shapes for insulation components.

• Importansya: Kini nag-enable sa silicone rubber insulators naka-custom-designed to meet specific application requirements, accommodating a wide range of electrical equipment.

Summary

Ang widespread use sa silicone rubber sa electrical insulation applications kay tungod sa iyang excellent hydrophobicity, resistance to tracking, electrical insulation strength, weather resistance, wide operating temperature range, ug self-cleaning properties. Kini nga mga katangian nag-siguro nga ang silicone rubber insulators ka effective sa high-voltage transmission lines, substations, ug power plants, especially in areas with severe pollution, harsh climates, or complex terrain.
