Our product portfolio includes pin type, suspension type, post type, and crossarm type composite insulators, designed to meet the electrical insulation, mechanical loading, and environmental requirements of different power line and substation applications. Manufactured with silicone rubber housings, high-strength FRP core rods, and metal end fittings, our composite insulators are engineered to provide reliable electrical insulation, mechanical strength, weather resistance, and long-term outdoor operating performance. We support power utilities, EPC contractors, and electrical equipment distributors with customized specifications and solutions tailored to project requirements.
Designed primarily for medium-voltage overhead distribution lines, pin type composite insulators are mounted on poles or crossarms to support and electrically isolate conductors. They offer a lightweight and durable solution for distribution networks.

Yes. Customization can cover product dimensions, creepage distance, mechanical load ratings, connection fittings, and other structural details.
IEC, ANSI, GB and specific technical requirements of customers. The specific standards can be confirmed based on the country where the project is located, the application scenarios and the procurement norms.
1.Appearance and size inspection: Confirm the structural dimensions, umbrella skirt and hardware quality. 2. Electrical withstand voltage test: Verify the insulation performance of ultra-high voltage. 3. Mechanical tensile test: Confirm the load-bearing capacity of the long bar structure. 4. Material and hydrophobicity inspection: Evaluate the long-term operational capacity of the composite jacket. 5. Factory consistency check: Ensure that batch products meet technical specifications.
Yes. Samples can be discussed for product evaluation and technical verification before bulk orders. Sample availability, specifications, production time, and shipping arrangements depend on the requested model and project requirements. Customers can also provide drawings or technical specifications for evaluation.
