Description

The 66kV composite suspension insulator is composed of a glass fiber epoxy core, silicone rubber sheds, and metal fittings. Low-voltage insulators exhibit excellent dielectric properties, adequate mechanical strength, and anti-aging capabilities under rated voltage.
During icing, charged water droplets are carried by the airflow into the radius area of the synthetic insulator sheds. These droplets experience rapidly increasing electric field forces, causing them to shift orbits. Consequently, the uneven capture of water droplets on various parts of the insulator surface and the unevenness of the ice layer are exacerbated.

Key Features

  • Wide Product Range

Overhead line high-voltage, extra-high voltage, and ultra-high voltage suspension products; high-voltage line post-type products; composite crossarms for distribution networks; composite post insulators for substation busbars and equipment.

  • Advanced Composite Materials

Manufactured with high-strength epoxy fiberglass cores and high-quality silicone rubber housings, they offer excellent pollution flashover resistance and anti-aging performance.

  • Lightweight & High Strength

At the same voltage level and mechanical strength class, composite insulators weigh only about 1/7 to 1/10 of ceramic/glass insulators, reducing steel consumption for towers and lines and significantly cutting infrastructure costs.

  • Excellent Electrical Performance

With a pollution flashover voltage more than twice that of ceramic/glass insulators, they minimize the risk of flashover failures caused by contamination, indirectly lowering operation and maintenance expenses.

  • Strong Weather Resistance

They operate reliably in harsh environments such as extreme cold, high temperatures, coastal areas, and heavily polluted regions.

  • Long Service Life

Thanks to an eco-friendly and intelligent manufacturing process, composite insulators offer excellent quality consistency and a service life exceeding 30 years.

Applications and Utility

  • Transmission lines and substations

Through material innovation and structural optimization, composite insulators achieve an optimal balance of high strength, lightweight design, and long service life. Offering high cost-effectiveness, they are critical components in modern power systems for enhancing line safety and are widely used in transmission lines and substations.

  • Ultra-High Voltage (UHV) Transmission Lines

Our composite insulators are extensively used in 1000kv,±800kV and other UHV DC and AC transmission projects, providing reliable insulation for critical national power arteries.

  • Converter and Substations

Composite post insulators serve as the external-insulation support components for all kinds of equipment in converter stations and substations, providing both electrical insulation and structural support for busbars and electrical apparatus.

  • DC and AC Filter Systems

Widely applied to support reactors and capacitors in DC and AC filter fields, which are crucial for maintaining power quality in the grid.

  • High-Voltage Electrical Equipment

Used as integral insulation components for various high-voltage equipment, including circuit breakers, disconnectors, and arresters.
