As a professional manufacturer with ISO 9001 certification, Jinhua Dika Electrical Equipment Co., Ltd. specializes in providing reliable high-voltage protection solutions for global power infrastructure. Our Customized High-Voltage Lightning Arresters are engineered to safeguard critical electrical equipment from damaging surges and lightning strikes across various voltage levels, including 11kV, 20kV, and 220kV. With over a decade of experience and products exported to markets worldwide, we understand the diverse requirements of different grid systems and environmental conditions. This arrester, featuring our advanced composite silicone housing, represents our commitment to durability, performance, and customization, ensuring your substations and transmission lines operate with maximum uptime and safety.
Core Product Features & Technical Advantages:
- Superior Housing Material: The arrester utilizes a high-grade composite silicone rubber housing. This material offers exceptional resistance to tracking, erosion, and UV radiation, maintaining insulation integrity and mechanical strength in harsh outdoor environments for extended service life.
- Advanced Surge Protection Technology: At its core, the arrester employs metal oxide varistor (MOV) discs with stable nonlinear characteristics. These discs provide a low clamping voltage during surge events, effectively limiting overvoltages to safe levels and protecting connected equipment.
- Robust Sealing & Construction: A hermetically sealed design prevents moisture ingress, which is a primary cause of arrester failure. The internal components are protected against environmental contaminants, ensuring consistent electrical performance.
-
Customizable Electrical Parameters: We tailor the arrester's specifications to match your specific system requirements. Key parameters available for customization include:
- Rated Voltage (Ur): 11kV, 20kV, 33kV, 66kV, 110kV, 220kV, and others.
- Continuous Operating Voltage (Uc).
- Nominal Discharge Current (In).
- Line Discharge Class.
- Pressure Relief Class (for safe failure mode).
- High Creepage Distance: The housing is designed with optimized shed profiles to provide a long creepage distance, enhancing performance in polluted or coastal atmospheres and reducing the risk of flashover.
- Easy Installation & Maintenance: Designed for straightforward pole or ground mounting. The lightweight yet sturdy composite housing simplifies handling and installation compared to traditional porcelain arresters.
Detailed Technical Specifications:
The table below outlines standard parameters for common voltage classes. All values can be adjusted according to your project's technical design.
| Parameter | 11kV / 20kV Class | 220kV Class |
|---|---|---|
| Rated Voltage (Ur) | 12kV, 24kV | 216kV, 240kV |
| Continuous Operating Voltage (Uc) | 9.6kV, 19.2kV | 172kV, 192kV |
| Nominal Discharge Current (In) | 5kA, 10kA, 20kA | 10kA, 20kA |
| Line Discharge Class | Class 1, 2, 3, 4, 5 | Class 4, 5 |
| Pressure Relief Current (kA, rms) | 40, 63 (Optional) | 63, 80 (Optional) |
| Housing Material | Composite Silicone Rubber | Composite Silicone Rubber |
Benefits for Your Project:
- Enhanced Grid Reliability: By reliably diverting surge currents to ground, these arresters prevent costly outages and equipment damage, contributing to a more stable power supply.
- Reduced Lifecycle Costs: The durable composite silicone housing requires minimal maintenance, is resistant to vandalism, and has a long service life, offering a lower total cost of ownership compared to conventional designs.
- Design Flexibility: Our customization capability allows you to specify arresters that perfectly integrate with your existing infrastructure, whether for new installations or retrofit projects.
- Global Compliance: Products are designed to meet international standards such as IEC 60099-4 and IEEE C62.11. Specific certifications can be discussed based on target market requirements.
- Safety Assurance: Features like a pressure relief system (if specified) provide a controlled failure mode, enhancing safety for personnel and surrounding equipment.

Frequently Asked Questions (FAQ)
Q1: What is the main advantage of a composite silicone housing over porcelain?
A1: The composite silicone housing is significantly lighter, making installation easier and safer. It is also highly resistant to cracking from thermal shock or mechanical impact, and its hydrophobic surface properties provide better performance in wet and polluted conditions.
Q2: Can you provide arresters for voltages other than 11kV, 20kV, and 220kV?
A2: Yes, absolutely. As a manufacturer specializing in customization, we can produce arresters for a wide range of system voltages, including 33kV, 66kV, 110kV, and other non-standard ratings. Please provide your specific system parameters for a quote.
Q3: How do I determine the correct line discharge class for my application?
A3: The line discharge class is related to the energy stress the arrester may experience. It depends on factors like system voltage, line length, and the type of system (ungrounded, effectively grounded). Our technical team can assist you in selecting the appropriate class based on your system data.
Q4: What is the expected service life of these arresters?
A4: Under normal operating conditions within their specified ratings, our composite silicone arresters are designed for a service life of 25-30 years. The actual lifespan can be influenced by the frequency and severity of surge events and environmental factors.
Q5: Do you provide test reports for the products?
A5: Yes, we can provide standard routine test reports for each batch, which include measurements of reference voltage, leakage current, and insulation resistance. Type test reports from independent laboratories are available upon request.
Q6: What is the lead time for customized orders?
A6: Lead time varies based on the order quantity and customization complexity. Typically, for standard customized designs, production takes 4-6 weeks after final technical confirmation. We will provide a precise schedule with your order confirmation.
Q7: How are the arresters packaged for export?
A7: Each arrester is individually packed in a sturdy cardboard box with foam protection. For high-voltage units (e.g., 220kV), they are often mounted on a wooden pallet and secured with plastic wrapping to ensure safe transportation by sea or air.
Q8: What after-sales support do you offer?
A8: We provide comprehensive technical documentation, installation guidance, and responsive support for any technical inquiries. Our quality commitment is backed by a standard warranty period, the terms of which will be detailed in our commercial contract.
