As a dedicated manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing high-performance composite suspension insulators designed for demanding 220kV power transmission systems. Our insulators are engineered to provide reliable insulation and mechanical support, ensuring the stability and safety of overhead lines. With our ISO9001-certified manufacturing processes and a commitment to quality, we deliver products that meet the rigorous standards of global power utilities. Each insulator comes with a comprehensive Mill Test Report, offering transparency and confidence in every component's performance.
Composite suspension insulators represent a significant advancement over traditional ceramic or glass types. They combine a Fiber Reinforced Plastic (FRP) core for exceptional mechanical strength with a silicone rubber sheath for superior electrical insulation and environmental resistance. This design addresses common challenges in high-voltage applications.
Key Features and Technical Advantages:
- Lightweight Construction: Composite materials significantly reduce the insulator's weight compared to porcelain, easing installation, handling, and reducing stress on support structures.
- High Mechanical Strength: The FRP core provides excellent tensile strength, capable of withstanding high mechanical loads (e.g., 160kN, 210kN, or higher) as required by line design.
- Superior Electrical Performance: The silicone rubber sheds and sheath offer stable dielectric properties, high creepage distance, and excellent resistance to surface arcing and flashover.
- Exceptional Environmental Durability: Silicone rubber is highly resistant to UV radiation, temperature extremes (-50°C to +70°C), moisture, and chemical corrosion, ensuring long service life in diverse climates.
- Anti-Bird Damage Design: The smooth, resilient sheath material is less susceptible to damage from bird pecking compared to porcelain insulators.
- Vandalism and Impact Resistance: Composite insulators are more resilient to accidental impact or vandalism, reducing replacement rates.

Frequently Asked Questions (FAQ)
-
What is a Mill Test Report, and why is it important?
A Mill Test Report (MTR) is a certified document provided by the manufacturer that details the results of tests performed on the raw materials and the finished product. For insulators, it typically includes data on mechanical strength (tensile test), electrical characteristics, and material composition. It provides traceability and proof that the product meets specified standards, which is crucial for utility procurement and quality audits. -
How does the composite insulator compare to traditional porcelain for 220kV lines?
Composite insulators offer several advantages: they are lighter, easier to install, more resistant to impact and vandalism, perform better in polluted or coastal environments due to the silicone rubber's hydrophobic properties, and generally have a longer service life with less maintenance. -
Can you provide insulators with specific mechanical strength ratings?
Yes. Mechanical strength (like 160kN, 210kN, 300kN) is a key customizable parameter. We design the FRP core to meet the specific load requirements of your transmission line project. Please provide your technical specifications during inquiry. -
What are the typical connection types available?
The most common connection types for suspension insulators are Ball & Socket (BS) and Tongue & Clevis (TC). The choice depends on the hardware used on your towers and conductors. We can supply either type based on your drawings or requirements. -
How is the product packaged and shipped?
Insulators are typically packaged in sturdy wooden crates or pallets to prevent damage during transportation. We ship from major ports like Shanghai, Tianjin, Guangzhou, and Ningbo, and can arrange shipping based on your destination and preferences. -
What is the expected service life of these composite insulators?
Under normal operating conditions, high-quality composite insulators can have a service life exceeding 30 years. The silicone rubber sheath is designed to resist aging from UV, temperature, and environmental exposure. -
Do you offer testing or certification according to international standards (like IEC)?
Our manufacturing process is ISO9001 certified, ensuring consistent quality control. The products are tested according to common industry standards. Specific standard compliance (e.g., IEC, ANSI) can be confirmed upon request, and relevant test reports are included in the Mill Test Report. -
Can you customize the insulator length or other dimensions?
Yes, key dimensions like overall length, shed spacing, and creepage distance can be customized to meet specific project requirements or regional standards. Please provide your detailed requirements for a tailored solution.
