Know about Composite Insulator

History of the Development of Composite Insulators

Composite insulators are made of silicone rubber material composite high voltage insulators. The main rod and cross arm style, 35KV/110KV / 220KV line as a drape and resistant sheets bearing insulation products, is also used for 10KV line insulator product. Different types of composite insulators in different purpose use, the silica composite insulators for substations, with good hydrophobicity, aging resistance, resistance to tracking and resistance to erosion resistance, high tensile strength and flexural strength. Its high mechanical strength, good impact resistance, shock-proof and anti-brittle fracture performance, light weight, easy installation and maintenance, its upper and lower ends of the installation size porcelain post insulators mounting dimensions can be used interchangeably.

Advantages of Composite Insulators

1. Superior mechanical properties: the mandrel is made of epoxy glass fiber, its tensile strength was 1.5 times that of ordinary steel, high-strength ceramic 3 to 4 times axial tension is particularly strong and has a strong vibration absorption capacity, high performance of seismic damping porcelain insulators, 1/7 to 1/10.

2. Stain-resistant flash performance: composite insulator is hydrophobic, synthetic insulators umbrella in the rain when the corrugated surface does not wet the water film is formed, was the drops of water like dripping, is not easy to have a conductive channel, the higher its pollution flashover voltage for same voltage levels porcelain insulator 3 times.

3. Galvanic corrosion resistance is excellent: the surface of the insulator leakage flashover formation irreversibility deterioration tracking phenomenon, the general standard of not less than 4.5 (ie 4.5kV) composite insulators for 6 to 7.

4. Anti-aging properties: after decades Practice detection of composite insulators in addition to the color darken slightly and the dielectric constant and dielectric loss angle slightly increased, the surface wettability and electrical erosion resistance no change of tracking sex, indicating a good anti-aging properties.

5. Structural stability: General porcelain suspension insulator assembly structure within the plastic, galvanic corrosion, insulation resistance of the low value of zero will run, and the composite insulators Cover assembly structure, its heart is a solid rod of insulating material, does not exist deterioration of aggregate breakdown, zero value does not appear insulators.

6. Line operating efficiency: synthetic insulators weatherproof self-cleaning, without producing zero value insulator, so the cleaning and inspection can be changed to once every four to five years, reducing maintenance outage time.

7. Light weight: with the insulator own light weight transportation, construction jobs, which can greatly reduce the labor intensity of the staff.
