Description
Technical Parameters
Gaodian Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of 20kv polymer post insulator ock 10-20-3a-01 in China. With abundant experience, we warmly welcome you to buy advanced 20kv polymer post insulator ock 10-20-3a-01 made in China here from our factory. We also accept customized orders.
Products Description
20KV polymer post insulator are designed to provide reliable electrical insulation and mechanical support for overhead distribution lines and electrical substations.
Made with a high-strength fiberglass core and a weather-resistant silicone rubber housing, our polymer post insulators offer dependable performance in outdoor environments exposed to moisture, pollution, UV radiation and changing weather conditions.
We manufacture composite post insulators in different voltage ratings, dimensions and mounting configurations to meet project requirements.
Key Features
- Mechanical Support
Holds heavy conductors and busbars firmly in place, withstanding severe mechanical stresses including wind, ice accumulation, and short-circuit electromagnetic forces.
- Electrical Insulation: Safely isolates energized high-voltage conductors from grounded support structures (metal towers, poles, or switchgear frames) to prevent flashovers and leakage currents.
- Lightweight Construction
Composite post insulators are lighter and easier to handle during transportation and installation.

FAQ
Q: Can you manufacture composite post insulators according to customer drawings?
A: Yes. GAODIAN can review customer drawings and technical specifications for customized production, subject to technical evaluation.
Q: What is the difference between a composite post insulator and a porcelain post insulator?
A: Composite post insulators generally have a lighter construction and use a silicone rubber housing, while porcelain post insulators use a ceramic body. The appropriate choice depends on electrical requirements, mechanical loading, environmental conditions and project specifications.
Q:What is the difference between a composite post insulator and a porcelain post insulator?
A: Please provide the rated voltage, mechanical load, creepage distance, overall dimensions, fitting type, required standard and estimated quantity. Drawings or a technical datasheet are also helpful.
