As a dedicated manufacturer, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing robust electrical protection solutions. Our Customized High-Voltage Arrester with Standard Compliant Design represents our commitment to safeguarding critical power infrastructure worldwide. Engineered for reliability and tailored to meet specific grid requirements, this arrester is a cornerstone for preventing costly downtime and equipment damage caused by transient overvoltages and lightning strikes. With over a decade of expertise and a global footprint across markets from North America to Southeast Asia, we deliver products that combine advanced technology with stringent quality control.
Our high-voltage arresters are meticulously designed to offer superior performance and longevity. The core advantages of our product line include:
- Tailored Protection: Every arrester is configured based on your system's voltage level, fault current, and environmental conditions, ensuring optimal coordination with your protection scheme.
- Advanced Core Technology: Utilizing high-purity Zinc Oxide (ZnO) varistor blocks with non-linear characteristics, providing excellent energy absorption and rapid response to surge events.
- Robust Construction: Available with either high-strength polymeric housings for lightweight, vandal-resistant performance, or traditional porcelain for proven durability in harsh climates.
- Enhanced Sealing: A multi-stage sealing system effectively prevents moisture ingress, a primary cause of arrester failure, ensuring long-term stability and insulation integrity.
- Standard-Compliant Design: All designs adhere to international standards such as IEC 60099-4 and IEEE C62.11, guaranteeing interoperability and safety in global power networks.
The technical specifications of our standard range can be customized. Below is a reference table for common configurations:
| Parameter | Typical Range / Value | Description |
|---|---|---|
| Rated Voltage (Ur) | 3 kV to 36 kV | Continuous operating voltage of the system |
| Nominal Discharge Current (In) | 5 kA, 10 kA, 20 kA | Standard lightning impulse current used for classification |
| Pressure Relief Class | Class 1, 2, 3, 4 | Fault current withstand capability for safe failure mode |
| Housing Material | Polymer (Silicone Rubber) or Porcelain | Determines mechanical and environmental resistance |
| Creepage Distance | Customizable per pollution level | Critical for performance in polluted or coastal environments |
Choosing our customized arrester translates into tangible benefits for your operation. You gain a system-specific solution that enhances protection selectivity, reduces the risk of unexpected failures, and extends the lifespan of connected transformers, switchgear, and generators. The standard-compliant design simplifies regulatory approval and ensures compatibility with existing infrastructure. Furthermore, the robust construction minimizes maintenance needs, leading to lower total cost of ownership over the product's life cycle.
Backed by our ISO9001 certified manufacturing processes and supported by a team of 11-50 skilled professionals, every Dika arrester is built to exacting standards. Our annual export value of US$1-1.5 million and service to diverse markets from Eastern Europe to Oceania stand as a testament to the reliability and acceptance of our products. We manage logistics efficiently through major ports like Shanghai, Tianjin, Guangzhou, and Ningbo, ensuring timely delivery. Trust Jinhua Dika to be your partner in power system protection.

Frequently Asked Questions (FAQ)
-
What does "customized" mean for a high-voltage arrester?
Customization involves adjusting key parameters like rated voltage, discharge current rating, housing material, creepage distance, and mounting configuration to match your specific application's electrical, mechanical, and environmental conditions. -
How do I determine the correct arrester rating for my system?
The selection depends on your system's nominal voltage, grounding type, insulation coordination plan, and the location's lightning activity. Our engineering team can assist you with this calculation based on your provided data. -
What is the lead time for a customized order?
Lead times vary based on the complexity of customization and order quantity. Standard customized configurations typically have a lead time of 4-6 weeks. We provide accurate timelines upon receipt of your detailed specifications. -
Can your arresters be used in coastal or heavily polluted areas?
Yes. We offer options with extended creepage distances and hydrophobic housing materials (like silicone rubber) specifically designed to perform reliably in such challenging environments. -
Do you provide test reports and certifications?
Yes. Our products are designed to comply with international standards. Type test reports from accredited laboratories are available upon request to support your qualification process. -
What is the difference between polymeric and porcelain housings?
Polymeric housings are lighter, offer better resistance to vandalism and cracking from thermal cycling, and have superior hydrophobicity. Porcelain housings are known for their long-term track record and high mechanical strength. -
How is the quality control managed during production?
Our manufacturing follows ISO9001 quality management system guidelines. This includes rigorous incoming material inspection, in-process checks, and final product testing (including routine tests like power frequency sparkover and leakage current). -
What after-sales support do you offer?
We provide technical documentation, installation guidance, and responsive communication for any operational queries. Warranty terms are specified in the commercial contract.
