As a dedicated manufacturer with over a decade of experience in high-voltage insulation solutions, Jinhua Dika Electrical Equipment Co., Ltd. specializes in producing reliable, high-performance ceramic post insulators. Our custom-designed 10kv and 20kV ceramic post insulators are engineered to meet the rigorous demands of modern power distribution and transmission systems. Backed by our ISO9001-certified quality management system and an annual export value exceeding US$1 million, we provide robust products that ensure safety, longevity, and optimal performance in diverse electrical applications worldwide. We understand that every power system has unique requirements, which is why we offer fully customizable solutions, from dimensions and creepage distance to mechanical specifications, all supported by a solid 1-year warranty for your peace of mind.
Our ceramic post insulators are crafted from premium-grade, high-alumina porcelain or steatite ceramic, materials chosen for their exceptional dielectric strength, thermal stability, and resistance to environmental degradation. The core advantages of our products include:
- Superior Electrical Performance: Excellent insulation properties prevent leakage currents and flashovers, ensuring stable operation under rated voltages of 10kV and 20kV.
- Exceptional Mechanical Durability: Designed with high bending and compression strength to withstand wind, ice, and mechanical loads, reducing the risk of breakage.
- Outstanding Weather Resistance: The high-grade ceramic body and brown glaze finish provide excellent resistance to UV radiation, moisture, pollution, and wide temperature fluctuations.
- Customization Flexibility: We tailor the insulator's height, creepage distance, shed profile, and mounting base (flange type, bolt hole pattern) to fit your specific system layout and environmental conditions (e.g., coastal, industrial, or desert areas).
- Long Service Life: The inert ceramic material does not corrode or degrade easily, offering a maintenance-free service life that significantly outlasts many alternative materials.
The primary technical specifications for our standard customizable models are outlined in the table below. Please note that all parameters can be adjusted according to your project's technical drawings or requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the lead time for a customized order?
A: Lead time depends on the complexity of customization and order quantity. Typically, for standard customizations, production takes 25-35 days after final drawing approval. We provide a detailed schedule upon order confirmation. -
Q: Can you provide insulators for areas with heavy pollution or salt fog?
A: Absolutely. We can design insulators with extended creepage distances, special shed profiles, or hydrophobic glazes to enhance performance in heavily polluted, coastal, or industrial environments. Please specify your site conditions. -
Q: What does the 1-year warranty cover?
A: Our warranty covers manufacturing defects in materials and workmanship under normal service conditions for one year from the date of shipment. It includes replacement of defective units. -
Q: Do you provide test reports with the products?
A: Yes, routine test reports (including power frequency withstand, lightning impulse, and dimensional checks) are available for each production batch. Type test reports can be provided upon request. -
Q: What mounting hardware is included?
A: The insulator is supplied with a galvanized steel flange base. Mounting bolts, nuts, and washers are typically not included but can be supplied as an optional accessory kit. -
Q: How do I provide my customization requirements?
A: You can share technical drawings, specifications, or a detailed list of requirements (e.g., dimensions, creepage, mechanical load). Our engineering team will review them and provide design feedback and a quotation. -
Q: What are the packaging details for export?
A: Insulators are packed in sturdy wooden crates or plywood boxes with internal cushioning to prevent damage during sea or land freight. Packaging is designed to withstand long-distance transportation. -
Q: Are your products suitable for both new installations and replacement projects?
A: Yes. Our customizable design makes them ideal for new switchgear and substation projects. They are also a perfect fit for replacement applications where matching existing dimensions or upgrading performance is required.
