As a professional manufacturer of high-voltage electrical equipment, Jinhua Dika Electrical Equipment Co., Ltd. proudly presents our advanced 220kV Lightning Arrester. Engineered for critical power infrastructure, this arrester is designed to provide robust and reliable overvoltage protection for transmission lines and substations, ensuring the stability and longevity of your electrical grid. With a strong commitment to quality underscored by our ISO9001 certification and a decade-long performance warranty, we deliver a product that meets the rigorous demands of global power utilities. Our extensive export experience, serving diverse markets from North America to Southeast Asia, equips us with the knowledge to provide solutions tailored to various climatic and operational conditions.

Our 220kV Lightning Arrester is a cornerstone for safeguarding high-voltage assets against lightning strikes and switching surges. Its core technology and construction offer distinct advantages.

Advanced Zinc Oxide Technology: At the heart of the arrester are high-grade zinc oxide (ZnO) resistor blocks. These blocks exhibit highly non-linear voltage-current characteristics, meaning they act as insulators under normal system voltage and instantly become conductive during a surge, effectively clamping the overvoltage to a safe level.
Robust Mechanical & Electrical Design: The arrester housing, available in high-strength porcelain or a composite polymer material, is designed for exceptional mechanical strength and pollution resistance. This ensures reliable performance in harsh environmental conditions, from coastal salt fog to industrial pollution.
Superior Energy Absorption & Durability: The design prioritizes high energy absorption capacity and long discharge durability. This means the arrester can withstand multiple high-energy surge events over its operational life without degradation, a key factor backed by our 10-year warranty.
Sealed & Maintenance-Free Construction: The unit is hermetically sealed to prevent moisture ingress, a common cause of failure in surge arresters. This sealed design translates to a truly maintenance-free installation, reducing lifecycle costs and operational overhead.
Accurate Protective Level: The arrester is precisely calibrated to provide a low residual voltage (protective level) relative to its rated voltage. This ensures that sensitive equipment downstream is effectively shielded, minimizing the risk of insulation failure and equipment damage.

The technical specifications of our 220kV Lightning Arrester are detailed below to provide a clear overview of its capabilities.

Parameter	Specification / Value
Rated Voltage (Ur)	220 kV
Continuous Operating Voltage (Uc)	As per IEC/IEEE standards, typically 176 kV
Nominal Discharge Current (In)	10 kA (Standard, other ratings available)
Line Discharge Class	Class 4 or 5 (Energy absorption capability)
Residual Voltage at In	Specific value available upon request
Housing Material	Porcelain or Silicone Rubber Composite
Pressure Relief Rating	High (for safe failure mode)
Creepage Distance	Customizable based on pollution level (e.g., 25 mm/kV or higher)

Choosing our arrester brings tangible benefits to your operations:

Enhanced Grid Reliability: By reliably diverting dangerous surges to ground, it prevents costly outages and equipment damage, contributing to higher system availability.
Reduced Total Cost of Ownership: The combination of a 10-year performance warranty and maintenance-free design significantly lowers long-term operational and replacement costs.
Global Compliance & Adaptability: Manufactured under the ISO9001 quality framework, our products are designed to meet international standards (IEC, IEEE) and can be customized for specific regional grid requirements and environmental conditions.
Technical Support & Logistics: With annual exports valued between US$1-1.5 million and shipments from major ports like Shanghai, Tianjin, Guangzhou, and Ningbo, we ensure efficient logistics and provide professional technical support for installation and application.

Frequently Asked Questions (FAQ)

Q: What is the significance of the 10-year performance warranty?
A: This warranty covers the performance and functional integrity of the arrester for a period of ten years under normal operating conditions. It provides assurance of the product's long-term reliability and reflects our confidence in its design, materials, and manufacturing quality.
Q: Can this arrester be used in coastal areas with high salt pollution?
A: Yes. We offer versions with specially designed creepage distances and housing materials (such as silicone rubber composite with hydrophobic properties) that are highly resistant to salt fog and industrial pollution, making them suitable for coastal and heavily polluted environments.
Q: How does the zinc oxide arrester compare to older gapped silicon carbide types?
A: Zinc oxide arresters offer superior performance: they are gapless, which eliminates the risk of gap contamination and provides faster response times. They also have better voltage-current nonlinearity, resulting in lower residual voltage and better protection for equipment.
Q: What standards does this 220kV arrester comply with?
A: Our arresters are designed and tested in accordance with major international standards such as IEC 60099-4 and IEEE C62.11. Specific compliance certificates for your region can be provided upon request.
Q: Is the arrester truly maintenance-free after installation?
A: Yes, due to its hermetically sealed design, the arrester requires no routine maintenance. However, periodic visual inspections as part of general substation maintenance are recommended to check for physical damage or contamination.
Q: Can you provide customized arresters for specific system voltages or requirements?
A: Absolutely. As a manufacturer, we have the capability to customize parameters like rated voltage, residual voltage, creepage distance, and housing color to meet your project's specific technical and aesthetic specifications.
Q: What is the typical delivery lead time for an order?
A: Lead times vary based on order quantity and customization. For standard models, we can often arrange shipment promptly from our stock. We ship via major Chinese ports (Shanghai, Tianjin, Guangzhou, Ningbo) to ensure efficient delivery to your destination.
Q: Do you provide installation guidance or technical support?
A: Yes, we provide comprehensive installation manuals, datasheets, and technical drawings. Our engineering team is also available to offer support and answer technical questions regarding application and integration into your system.
